Do you own a 2001, 2002, 2003, 2004 or 2005 Toyota Rav4?
Are you having problems with the automatic transmission? The transmission acts erratically? Loss of power when accelerating or launching in other than first gear? Engaging harsh in reverse like in a bump? Slipping from 2nd to 3rd gear?
All those are problems caused by a defective ECM or Engine Control Module, a.k.a “Car Computer”.
The good news is that we have a solution for getting rid of the problem for good and prevent imminent damage to your vehicle’s transmission.
For more testimonials and other information you may visit our Facebook page at:
We are offering a REPAIR AND RETURN service for your Toyota Rav4 ECM (a.k.a ECU). You send us your defective ECM, we repair and reprogram it and then it is shipped back to you. Our turn around time is one business day for most of the times or 2 business days when the workload is high. International orders are welcome too.
Shipping
Shipping
We offer FREE return shipping through USPS Priority Mail to Continental USA, including also, Puerto Rico, Hawaii, Alaska, Guam, American Samoa, and US Virgin Islands. For international locations (out of the USA), return shipping cost will be calculated for FedEx shipping service. Return shipping to Canada can be done through USPS too, but unfortunately, we have no free options for it at this moment.
This is affecting more than a million units all around the world. It is so common that Toyota issued an “enhanced warranty” on this, which is long expired now.
This service covers 2001-2005 automatic Rav4 models, either 4WD (4 wheel drive or 4×4) and 2WD (2 wheel drive or 4×2). It also covers the Toyota Picnic and Toyota Avensis models of the same years (2001-2005).
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 take a little more time because in some cases, we need to fix additional problems induced by any previous repair attempt, but we will gladly accept your unit and do our best to help WITHOUT adding any extra cost to the repair job.
Symptoms
The following are the most common symptoms of this issue with the ECM:
- Check engine is not triggered in most cases
- When Check engine is triggered, it commonly shows P0750, P0753, P0755, P0758 and/or P1760 trouble codes when scanned
- 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 if in neutral gear
- Some days it fails and some other days it works with no issues
- The problem is there only when the engine gets warm or only when it is started the first time in the morning
- When stopping completely and moving again, it loses power and feels sluggish or heavy
- Lower fuel economy. Spends more gas than usual
ECM Part Numbers
This is a partial list of the ECM part numbers affected. You will find the part number on the label at the top of your ECM. It starts with “89661”. Not all numbers are covered here, so if you don’t see your ECM number in the table below or if you are in doubt if your ECM is part of that list, please feel free to contact us to ask.

ECM Location
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 in the long run and the others 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 few years if it is not corrected. We offer the most complete service for these units, as we cover the whole unit, not just the transmission problem and not just the symptom of the problem, but the cause of the problem too.
Do you actually repair or reprogram the ECM?
We do both. We offer the most complete service available for these units:
- We first repair the circuit and replace any needed parts.
- Second, we reset the transmission adaptation table memory, so it starts relearning from zero when it is installed back. If your vehicle is equipped with the immobilizer security system, we reset it too to make sure the engine will start when installed back after it has been serviced.
- Third, we recondition the whole circuit to prevent future problems with any other area.
- Fourth, 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. If your ECM’s software is outdated, it won’t leave our shop without been updated.
- 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.
Will I have a tracking number?
Sure! When you send your unit to us and we receive it, we will notify you and will do the same when it is completed and shipped back and will notify you of the tracking number. If you do not receive an email from us, it probably is in your email’s spam folder. To some users, we will try to notify from an alternative email if our system tells us that the email was denied or if it bounced. But when the system says “email delivered“, sometimes it lands in the “spam” folder. It depends on the way the email server of your email works. Our emails bounce the most from Yahoo mail. That is why, though it is optional, it is a good practice to (1) create an account with us when ordering instead of ordering as a guest and (2) leave your phone number in the order.

Removing the ECM from your vehicle:
Tools you will need:
- Short #2 Phillips screwdriver (stubby)
- Regular #2 Phillips screwdriver
- 10MM Socket Wrench
- Flashlight.
The kick panel and the scuff plate should be removed first, before starting the ECM removal procedure (check the first drawing below).
Now, proceed to:
1. Open the glove compartment box. There are two plastic pins, limiting its opening, one on each side at the inner end of the box. Push the two inner edges inwards, so the glove box gets disengaged from its place.
2. Now, with the regular Phillips screwdriver, remove the two screws in the lower part, that are holding the glove box to the dash.
3. With the glove box completely out, find the ECM computer at the right, which is a metallic box with 5 wiring connectors on it. It is near a smaller metallic box.
4. Unplug the 5 white wiring connectors one by one, by pushing on a locking plastic clip that each connector have while pulling the harness out at the same time.
5. With the 10mm socket wrench, remove the 10mm head bolt that attaches the ECM to the bracket at the lower part (refer to the second drawing below) and with the short Phillips screwdriver, remove the two screws at the top.
You might need a flashlight here to easily find those two upper screws and you might also need to move any wiring away, that might be in the path for taking the ECM out.
6. When the ECM is loose, carefully slide it downwards. It will come out with the rear bracket attached to it, so when it is out, remove the four Phillips screws as shown in the second picture below.
That’s it. You may pack it in a small box and send it to us!
*** IMPORTANT NOTE ***
If your Rav4 does not engage into reverse AT ALL, at that point, it means that the ECM is damaged, BUT the damage went beyond the ECM, into the transmission. Please refer to our list of symptoms elsewhere in this page.
The ECM controls all the forward gears (1st, 2nd, 3rd, and 4th), but it does not control the reverse. The reverse, even when affected by a damaged ECM, like bumping when put in reverse, the reverse is mechanical and not controlled by the ECM.
What we mean is, the ECM must be repaired, but so the transmission. A good or properly repaired ECM must be in place in order to avoid damaging a new, used or repaired transmission in case you decide to repair your car. Repairing your ECM in these cases will be the first step.

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.
I would like to thank Sir Richard for doing a superb job in giving my car’s computer box a second life. He answers my emails everytime and is very nice. Now, my car runs as smooth as new. 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.
Service was very fast and they did a great job. They repaired my ECU and i got it back working great! They gave my Rav4 a second life. Highly recommend them
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.
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.
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.
Just perfect. I wasn’t able to get this less expensive than your price here. My car is fine now. Thank you.
antes de comprar el servicio, el electromecanico no daba “pies con bolas”. Ahora la guagua funciona perfecta. Gracias mil.

Am very very happy with the service you rendering. Am from Ethiopia,East Africa. I owed Rav4 2002. After my car exprienced the ecm problem,I was shocked as I used all my money to buy this car. I started searching on webs. finally,I idetntified the problems on these models Rav4(2001-2003)-. I very happy now. I got Mr.Richard from otherdeal.com. he helped me a lot. He told me to send the ecm to the mentioned address. I did it. Thanks a lot Mr.Richard for the discount you made for me by understanding my matters.

Very trustworthy, excellent and fast service. My RAV4 SUV drives like new again. I will blindly recommend you guys to any one as I am very pleased with the service you provided.
Great! You put my RAV4 back in the road again after i though it was a major problem. Luckily I found you and that offered this service also out of the USA.
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.
Hey Richard. I a sorry I did not emailed you earlier. I wanted you to know that my rav4 is working flawlessly since I installed the repaired ecu. Thank you. You are definitely recommended to all my friends.
I had my ecu repaired and rec’d it back within a week after sending it for repair. I am very satisfied with the turnaround and the repaired product. i installed it and now it’s working great without replacing my transmission. Thank you very much Richard !!!
Incredible guys. Thank you for all your support and for fixing my rav4ecm so perfectly. please I would like to separate a rebuilt ecm of the same whenever you have it available. I want to have it handy in case my second rav 4 fails with the same issue.
Perfect – Fast – Five Star PLUS +++ – As advertised in every way – From a tranny that felt like it was going to fall out of the car, back to new – this is not the ‘other deal’ it’s the REAL DEAL – Thanks Richard, you’ve made my daughter’s RAV4 back to new – I’ve never written a product review ever but I made an exception this one time since I’m blown away – Maryland USA.
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
The repairs were done in a timely fashion and the vehicle shifts better than ever before. I’m very pleased with Richard’s service and highly recommend this repair for other Rav4 owners experiencing shifting issues.
WHAT DID YOU DO TO MY ECM!!!!!!!!!!!!-!! 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 commend the professional and timely manner in which this service for my 2003 rav4 was done. My Rav4 transmission now shifts smoothly, the jerking has stopped and my car is back to normal. Thank you Richard. Ken…
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.
Richard- I received my ECM back today, had it installed in less than 10 minutes and it worked flawlessly. Thank you for providing this service. Great job and if my repairs require your expertise I won’t hesitate to call upon you again. Best of luck! William French
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.
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.
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
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
hello i sent my ecm to the this company ..i have to apologize that i didnt beleive that they could fix it but when i got it i didnt beleive on my eyes PROBLEM WAS FIXED and car has changed to 100% better THANK U GOOD JOB
I got your remanufactured rav4 2001-2003 ecu and i must tell you, my rav4 works so great i cant stop talking about the change. all the noises around and under stopped, my check engine light that refused to go just vanished. surprisingly also, fuel consumption dropped drastically and noticeably. thanks as i have spent a fortune here in Nigeria to get all these fixed but they seem not to understand the problem. thanks so very much.
Gracias Richard por tu excelente sevicio y trato personalisado me ahorre un monton de dinero y rav4 esta en excelente condicion quedo mejor que nueva.
My local Toyota dealer was not honest with me about the ECM being the culprit..even after I told him of the obvious clue..a slipping 2-3 upshift. Otherdeal fixed my unit, got it back fast, and the car runs perfectly…Ric-hard saved the day.
I was very scared when I found out this company was located outside the U.S.A. and certainly did my home work, even on a Sunday evening sitting on my sail sail boat, sent an email to the company the owner instantly reassured me they were legit and had great confidence in repairing my ECU, I recieved my ECU, in perfect condition packaged nicely, reistalled and cannot believe how the car returned to it’s original condition if not even smoother shifts than new, Richard was amazing and the work first class, I now show everyone with RAV4 issues this site and will be the first to use in the future….Nicho-las
I commend the professional and timely manner in which this ECM Repair Service for my 2003 Rav4 was done. My Rav4 transmission now shifts smoothly, the jerking has stopped and my car is back to normal. Thank you Richard. Ken…

Hello Larry. I am glad that all is good, Thank you for your business 🙂
