Do you own a 2001-2005 Toyota Rav4 and are having issues with the automatic transmission? We can help!


If you own a 2001-2005 Toyota Rav4 and are having intermittent problems with the automatic transmission like loss of power when accelerating or when going uphill, or if it seems to be stuck in high gear, or if it is engaging harshly when it is put in reverse, or if it is slipping from 2nd to 3rd gear, you should know that all these issues are caused by a defective ECM (Engine Control Module), also known as ECU (Engine Control Unit).


We have a perfect, durable, and affordable solution for you. We offer a repair service for your ECM to get rid of the problem for good and prevent imminent damage to your vehicle’s automatic transmission. Just mail us your ECM after completing your order and we will repair, reprogram and test your ECM before shipping it back to you.


Our turnaround time is only one business day. This service covers the 2001-2005 automatic Rav4 models, either 4WD (4 wheel drive or 4×4) and 2WD (2 wheel drive or 4×2), either regular or “Japanese” versions, either left-hand or right-hand steering and also cover the Toyota Picnic and Toyota Avensis models of the same years (2001-2005).


As part of the service, the immobilizer (if present) is reset so your ECM will start your car’s engine no problem after been serviced, also the transmission relearn memory is reprogrammed so it starts relearning from zero right after installing it back in your car. This is a good practice, especially because your ECM will still have wrong codes in memory from the previous failure and if this relearn memory is not reprogrammed, it will present problems on driveability immediately.




The following are the most common symptoms shown for this issue with the ECM. You may experience one or more of these symptoms at the same time. If you have experienced at least one of them, then the ECM needs service ASAP:

  • In most cases, the check engine light is off, and no error codes when scanned
  • DTC trouble codes, when present, often are any of these: P0750, P0753, P0755, P0758, and P1760
  • Hesitation or harsh shifting, mostly from 2nd to 3rd gears
  • Slams into gear when putting it in reverse
  • Sometimes the vehicle feels like braking by itself
  • Erratically shifts on an intermittent interval
  • Rattling or clicking noise coming from the engine bay when the engine is running. Even in neutral gear
  • Some days it fails and some other days it works with no issues
  • The problem shows only when the engine gets warm or only when it is cold
  • After a complete stop, the moment you move again it feels like towing a heavy load
  • Lower fuel economy than normal. Consumes more gas than usual



Tampered Units


Did you already service your ECM with any other shop or Company and they could not fix it? Or did you try fixing it yourself and it did not work? No worries, no shame. We accept those units too. ECMs that have been serviced or attempted to be serviced previously by others or by yourself may just take a little more time, but we will gladly accept your unit and do our best to help WITHOUT adding any extra cost to the repair job.

shipping methods smallShipping


For returning the repaired ECM we use FedEx and USPS. a FREE option is offered to locations in the USA, including the 48 contiguous States, Puerto Rico, Hawaii, Alaska, and US Virgin Islands. Faster (paid) shipping options are available too. For international locations (out of the USA), we, unfortunately, do not have a free option yet, but we have special low rates through FedEx for it.


All available rates for your location can be calculated from your shopping cart with the provided shipping calculator (if available, postal code is needed for shipping rate accuracy).


Some common questions:



Wouldn’t it be better if the ECM is replaced by a new one?


Either brand new or used (recycled) ECMs are giving the same problems. The brand new fails in the long run, maybe a couple of years and the others do it in a few months. Also, the repair cost of the ECM is a lot less than the cost of a brand new replacement ECM that would fail again in a couple of years if its circuit is not corrected.


We offer the most complete service for these units, as we cover the whole unit, not just the transmission problem. This way, future problems, whether related to the actual problem or not, will be avoided. We can proudly say that this is one rare case where ordering this service is better than buying a brand new part.

Do you actually repair or reprogram the ECM?


We do both. We repair and then reprogram the ECM.

Why send it to you?


This is a good question, taking into account the many competitors that have surfaced in the last years and more importantly, the many different prices available, including very low ones. Remember that when something seems too good to be true, it probably is. Nevertheless, we offer very affordable prices for all the value we put in. Why us?:

  1. We first repair the circuit and replace any needed parts.
  2. We reset the transmission adaptation memory so it starts relearning from zero when it is installed back in the vehicle.
  3. If your vehicle is equipped with the immobilizer security system, we reset it too, ensuring that the engine will start when the ECM is reinstalled.
  4. We recondition the whole circuit to prevent future problems with any other area.
  5. We check if there is an update available from Toyota for your unit. If there is one, we do the update by installing the latest software version available for your ECM (only for USA models).
  6. Finally, it is tested in an actual vehicle. This is done with the USA and Canada Market models. Japanese and European market models will be bench tested for transmission functions and vehicle tested for engine functions.
  7. We have vast experience with these units and know all about the circuit. That is why, unlike our competitors, tampered units do not scare us.


Will I have a tracking number when it is shipped back?


That is for sure! When you send your unit to us, as soon as we receive it, we will notify you and when it is completed, we will also notify you of the shipping details and the tracking number. The notifications will be sent through email and SMS text messages when you register a mobile number in your account with us. A copy of any notification will also be privately posted in your account.

rav4 ecm removal 1   rav4 ecm removal 2




If your Rav4 does not engage in reverse AT ALL, at that point, it means that the ECM is damaged, BUT the damage went beyond the ECM, into the transmission. The ECM controls all the forward gears (1st, 2nd, 3rd, and 4th), but it does not control the reverse. The reverse is purely mechanical even when it is sometimes affected by a damaged ECM, like bumping when it is engaging. It means that the ECM must be repaired, but so the transmission. A new or repaired ECM must be in place in order to avoid damaging a new, used, or repaired transmission. In these cases, repairing your ECM will always be the first step.

ECM/ECU (Engine Control Module / Engine Control Unit)



Instructions Included



Toyota / Fujitsu-Ten


This is a REPAIR SERVICE, not a replacement part. We repair and reprogram your unit and ship it back to you ready to be used.


The included warranty term (stated at the top of this page) covers the job done in the ECM and any parts replaced. In the rare event that the ECM fails again, showing either the same or similar problems as before, we will consult the customer about the symptoms and if the ECM is suspected to be the culprit, it will be taken back for service at no cost for the job or parts.

While the job would be done at no cost and needed parts would not be charged in the period covered by the warranty term, inbound and outbound shipping costs will depend on the case, as described below.


A. If a claim is filed anytime within the warranty period and the problem is caused by something we did wrong (errors or mistakes in the repair process), if it happens in the first 30 days of the warranty period, we will cover both ways shipping. If it happens after the first 30 days of the warranty period, then we would only cover return shipping (from our location to the customer’s location).

B. If the claim is filed within the warranty period and it was not our fault, for example, a different part or different circuit is damaged this time and it was not caused by our previous intervention with the ECM, or if the same part is damaged, but because of an external cause as defined below, then we will still cover the job and needed parts for servicing it again, but the customer would need to cover both ways shipping.


1. The ECM was soaked in water or any other liquid.

2. The ECM fell from a considerable height or was hit hard (ex. an accident), causing internal damages to the circuit.

3. Short circuit in the vehicle’s wiring or problems with the electrical system of the vehicle.

4. Battery polarity reversed.

5. The ECM was used in an application that the ECM is not intended for (different car, different make, model or different setup).

6. The ECM was tampered with, either by opening it or by connecting wires to the ECM’s terminals other than the ECM’s wiring harness.

7. The use of piggybacks – External modules connected to the ECM terminals in order to modify the received signals (mostly done for engine performance).

8. Broken warranty seals indicating tampering.

If the ECM fails again and the issue is not related to what we did, we can take a look at it and repair or correct the problem if possible at no charge to the customer, but shipping would need to be covered by the customer. We agree to correct any other problem that could appear in the module even if it is has nothing to do with our previous intervention or previous problem as long as it is possible and doable.

Once we receive your ECM to be repaired or reprogrammed we will notify you and most of the time it will be serviced the same day.

After your ECM is completed, usually the next business day, we will also notify you and the unit will be shipped back.

The shipping details and a tracking number will be emailed to you as soon as shipping is done. You may also receive an SMS text message as an alternative way of letting you know in case the email fails to reach your inbox or in case it goes to the spam folder. For this, it is optional but recommended that you enter a mobile phone number when ordering, instead of entering a landline phone number.


There is a FREE shipping option (through USPS) for USA locations. The free option covers the USA mainland, Puerto Rico, Hawaii, Alaska, and US Virgin Islands.

Delivery time for the offered free shipping option to USA locations will be 3 to 5 business days. On the other hand, the paid USPS and FedEx Express options for USA locations will be next business day for FedEx Priority or 2-3 business days when USPS Express or FedEx Economy are used.

The only exception about using FedEx to the USA locations is if the shipping address is a PO Box or an APO (Army Post Office box). We do ship to PO Boxes and APOs, but in those cases, shipping will be done through USPS, which would be USPS Priority Mail for the free option or USPS Express (Priority Express) for the paid option. USPS options will take slightly longer transit times than FedEx.

Depending on the case, units in warranty could also be shipped through USPS Priority.


At this moment we, unfortunately, have no free options for international locations and we hope we can offer some kind of free international shipping in the near future.

Import Customs clearance in the destination country may add one or more days to the delivery time when shipping to international locations (out of USA).


You can calculate the exact shipping rates available for your location with the provided calculator, shown in your cart when you Add-to-Cart any product or service. There is no need to log in or have an account for doing this.

It is important that the Country and postal code are entered for getting accurate rates. Please note that the rate calculation will often be way off (higher or lower) than the actual rate if the needed information is not entered or is not accurate when using the rate calculator, specifically, Country, Postal Code if available or City if Postal Code is not available in your location.

We DO NOT profit from shipping. Any rate shown by the provided calculator is passed to you directly from USPS and FedEx through our API connection (Application Programming Interface) to our accounts with both Companies. Any time they do any changes in prices, it will be automatically reflected in our calculator.

Thank you!

    wonderful experience Richard is awesome and knows his stuff, don”t be afraid to send your ECU to PR they are the real deal and will get you back on track quickly, my 2004 toyota RAV4 runs strong and shifts nicely now, way better than before if you ask me, with over two hundred and forty thousand miles on the clock it was given a second chance at life thanks to these guys, i can vouch for them, thanks Richard from Kevin from NYC.

    I bought a repair service for a 2003 Toyota Rav4 in March 2017 and so far so good no problems, my customer still bringing the car for service to me, Delivery was pretty fast. if I have another ECU service I will definitely use this company again.
    Thank You

    I bought my car used for only a couple hundred dollars because the previous owner had been told it needed a new transmission. I found this fix while researching transmission problems and figured I’d rather try this first. I use my car everyday. No problems.
    Getting the unit out was the hardest part and that only took maybe two hours. I had my sister put it back in while I was on vacation. Too easy.
    Definitely worth it!

    My rav was financed and in the first 3months I had to replace the engine so when the ecu went out 1year later I didn’t know how I was going to come up with the $2000 Kendall Toyota quoted me. When I found this service I was reluctant but figured the price was worth the risk…so glad I did it! It was returned (in hand) in less than 3 days and I’ve had no problems. Thank you

    Dealer quoted me a new transmission and ecu to fix the shifting issues on my RAV4. Repairs that would cost twice the amount I paid for the rav. The repaired ecu gave the RAV4 a new life and saved it from ending up in the junk yard, it’s been perfect for close to two years now since the repair. Many thanks!

    With my son having picked up a 02 Rav4 from a not so honest person, he began having tranny problems. Doing research I found Richards website. Never occured to me it would be ECM related. I shot off an email with a few questions, not expecting such a quick reply!! Richard not only reassured me about his service, he gave me a nice fat discount! I used that savings to expedite shipping both directions. 4 days!! Yes 4 days and the ECM was returned, installed and my son back on the road. Long story yes but….

    I cannot express enough how well Richard runs his company. From start to end his professionalism shines like the sun!
    DO NOT SHOP ANYWHERE ELSE! You have found the right place!! Fear not for you’re in good hands. This is the person you want to deal with! Thank you Richard! — feeling super.

    Dear Richard and team, I am so happy that I found your repair service for ECM RAV4 cars online, especially after the resonse from my Toyota dealer that replacing the ECM with a new one would cost 1.500 EUR. You did a fantastic job and it was always comforting to know to receive replies to my questions right away. Your information was always very detailed and professional so that I knew that the ECM is in good hands. My car runs perfect again and I am glad that I could save that much money. I will definitively recommend your service here in Germany! Many thanks, Katrin

    Hi, I am from Belgium (Europe). At first I hesitated a lot to send my ECU so far with the risk of loosing it … Also, I was not 100% sure of this service. I had almost all the problems with my RAV4 that were described … So I took the risk and removed the ECU, packed it very well and send it with tracking so I could follow my box. It arrived after 7 days. That day I got confirmation of Richard that my box had arrived. He also reeplied on my mails. 4 days later (with a weekend included) I already received my ECU back ! There was a note included that they had repaired it, reset it and tested it. I almost immediately installed in in my car and … it worked like new ! No problems anymore until now (I have tested it for 4 days now) Thanks again for a very good service Rudi

    I’m a single mom who tries to repair things myself out of necessity. I bought a used 2003 Toyota RAV4 earlier this year and noticed issues of stalling and the vehicle surging forword between automatic first to second gear transitions. I was very worried wondering how I was going to pay for a new ecm and then wondering if it would even help. I knew the vehicle wasn’t safe to drive with these issues. Then I found Richard’s ecm repair service on the other deal as I google searched ecm repair. I sent my ecm to Richard in Puerto Rico. I got it back within a week, repaired and ready to go. I put it back in a few months ago, and I have had no issues since. I have been so happy and very relieved that my vehicle is working fine and is safe to drive with my children on board. I was so thankful it was something I could afford. I felt like I should get back on the site today and recommend this service. Most people seem to like to get on reviews to complain about something, but most people forget to say thanks when everything works out great. It was also the reviews on this site that helped give me the courage to go ahead and send in my ecu for repair. Don’t give up on your Toyota RAV4 because of ecm issues, send your ecm to Richard for repair, and you will not be sorry.

    Like a few others, I was a bit apprehensive about trying this repair but I decided it was worth the risk given the alternatives. I got the ECM back the other day, installed it, and the car is working perfectly. Richard provided communication upon payment, receipt of the unit, and return shipment. If you are faced with this problem, I can certainly recommend this service. I think I just saved over $1000.

    Richard, I was hesitant & a little concerned about sending my RAV’s ECM off in the mail to get repaired but after reading all the positives & not finding negatives, I went for it with you guys and I have to tell you: I put the unit back in today & it drives BETTER THAN IT EVER HAS since I have owned it! You saved my a$$ & my tranny. You did what you said you would & when. The RAV actually idles better & shifts very smoothly. You were very patient w/ this nervous customer & answered my qts along the way. THANKS SO MUCH & I plan on putting this out on FB as well. Job extremely well done. Since the car was out of commission, I put on new sway bar links & an in cabin air filter. She is like new again.

I want to thank you for the MAGIC you performed on my ECM, i purposely do not send you a mail concerning this service until after 2 months or so, ever since i installed the repaired ecm, my rav got born again and its been at the top of performance ever since, initially i thought it could develop the same problem again, but its running better and better each day, no more noise, sudden breaks, ranting etc, i can now climb any hill without fear of loosing gear, im really grateful.

    i wanted to say thank you so much, my Toyota rav4 shifts and runs like new!! i didn’t think that a ecu would cause such problems and i’m a mechanic and have been one for 30 years, i’m a believer and any one that has problems with there Toyota rav4 shifting funny needs to send your ecu to Richard and he will take care of you as he did me, thanks again Richard, your the man…….James

    This is real. He fixed it and mailed it back in one day. It works like brand new. People laughed at me when I told them that I just mailed my ECM to some dude in Puerto Rico. I am the one laughing now.

    I want to thank you guys. Transmission problems were driving me crazy that I opted not to use my SUV until I found this. I was wondering if you are interested in buying the old computer? I guess you are able to fix it.

    Hello Larry. We have many reviews, but since we moved here from a previous website, we are still integrating other functions of more priority. Reviews will be imported from our old website later on. The ones here were left after we moved in. Thank you for your comment.

    My car was behaving so weird, nothing was going well, car could not climb any hill and gallops on good road. The mechanic finally diagnosed it was the ECM that was faulty and no one could repair it out here in Cameroon. I researched online and met this company and i sent ECM to the US for them to repair it. My ECM was repaired, reprogrammed and tested before being shipped back to me. It worked perfectly well and my car is very ok now. Thank you very much Richard for saving my car.

Im glad that i sent the ecu to him and not anywhere else and be ripped off. Thank you so so much sir richard for a geat great job.

    I have been driving my 2003 Rav4 for a couple days now and could not be happier with your services. I was only on my second tank of gas since purchasing it when i discovered it had shifting issues. My cars symptoms were very occasional. Sometimes a slightly harsh shift from 2nd to third. A few times it started out from a stop in a higher gear. Twice i noticed extreme slippage when shifting into 3rd. So I parked it and found you on the web.

    The car now shifts perfect in every situation. I had an occasional low, slightly rough idle which i did not realize initially was related to the ecm and that is fixed too. It seems I caught it early enough before it damaged the transmission so all looks good.

    I also have to mention i was impressed with your professionalism as far as communication and how quickly you turned it around and got it back to me.

    Everything as advertised!

    Thank You,

    James B.

Question about 2001-2005 Toyota Rav4 ECM Repair Service

    Name (required):

    Email (required):

    Your Question or Inquiry (required):

    Here we are listing some questions and answers that we often receive about this service.
    1. What do I need to send to you for doing this service?
    We only need the ECM that will be repaired. Please, without the brackets. The ECM has three brackets for attaching it to the vehicle. If you include the brackets, it will be more difficult to ship and shipping will also cost more, because of the extra space that such brackets take.

    We understand that sometimes, either the screws used to attach the brackets are very, very tight and the screw heads get deformed in the attempt of removing them, or in some other cases, the manufacturer used non-standard security Torx screws instead of the common Philips screws. In those cases, just send it with the brackets.
    2. May I send only the circuit board? You know, without its metal case?
    Unfortunately, even when shipping would be even lighter that way, we can not accept units without its metal case or metal box. A warranty could not be offered if the unit comes without its metal case, as the unit would be vulnerable to shipping damage and tampering. Also, we place warranty labels on the finished ECM to prevent tampering. Preventing tampering allows us to offer a warranty in first place. Such labels could not be put if there is no metal case.
    3. My vehicle has the immobilizer feature. Do I need to send you the car keys along with the ECM?
    No, we will not need the keys. We will reprogram your ECM in a way that it will re-register and work with your current keys.
    4. Do you need the VIN number?
    No. The VIN number is not needed and not altered during this service either. Different from other Toyota models, the VIN number is not stored in this ECM.
    5. Do you reprogram the ECM as part of the service?
    Yes, in two ways. First, we reprogram the transmission adaptation memory for clearing it. By doing this, the wrong codes learned by the ECM when its was failing, are cleared so it relearns the correct codes when it is reinstalled. Second, if the ECM requires an update of its internal software (firmware), an update is programmed into it by using the latest version from Toyota. We always check that every ECM we service has the latest software version installed before it is shipped back to our customers.
    6. You charge a shipping fee. Do you send a shipping label for shipping the ECM to you?
    No, Shipping the ECM to our location is done on the customers' behalf. The shipping fees we charge are for sending the repaired ECM back to you. This charge is FREE if shipped to the USA. In those cases, it is shipped through USPS Priority Mail (3-5 business days). Paid shipments are also available if a faster shipment is needed (USPS Express Mail and FedEx). Unfortunately, we have no free shipping options for international locations (out of the USA) at this time.
    7. Do you accept international orders?
    Yes. International orders are welcome. We offer our service to all countries. Shipping to international locations (out of the USA) are done through FedEx. In the case of Canada it can be served either by USPS or FedEx.
    8. I have an account with a shipping company (USPS, FedEx, DHL, UPS, TNT, ARAMEX etc). Can I pay only for the service and ship using my account?
    Sure, it can be arranged. Just let us know and we will give you the details. We do not profit from shipping, nor we charge any handling fees. The rates we use are directly returned from USPS and FedEx APIs (Application Programming Interface) that are directly connected to our website when doing the shipping calculation. So if you want to use your own shipping account with any company, it can be fixed no problem.
