The 2001-2005 Toyota automatic Rav4 models, either 4WD or 2WD, are commonly having issues with the transmission and symptoms may suggest that the transmission needs repair or replacement. Many times, you will fill like your transmission is falling apart in these models, but the good news is that in 99% of the cases, the problem is a bad ECM (Engine Control Module) and we can fix it for good at a very affordable price. This ECM module controls the engine and the automatic transmission of your Toyota Rav4. We offer a professional solution for repairing and rebuilding the ECM and the job is backed by a 2-year warranty.

We started servicing 2001-2002 Toyota rav4 automatic transmission problems, then 2003 Toyota rav4 transmission problems and now we have extended our services to fix 2004 Toyota rav4 automatic transmission problems and for 2005 models too.


Q: There are many competitors, bringing this service. So you might be asking yourself, why sending it to us?

A: Simple. Because we go further than all our competitors to make sure that you will have the best experience with us and to make sure that this issue will not happen again to your vehicle. We do not only repair the problem, but we reprogram the ECM, fix minor issues that the customer might not even be aware of and finally, we rebuild the complete unit.

We constantly receive units that were previously worked out by our competitors. These units have been sent to us by unhappy customers, trying for a second time to fix their ECMs, because all previous service attempts failed. This is why we know of the poor job that many of our competitors do.

You may read more about this in the following article - 2001-2005 Toyota Rav4 transmission failure

How it works?

After you complete the order, you would need to uninstall (remove) your ECM from your vehicle (easily done, no mechanic needed), and mail it to our location. We repair, rebuild and reprogram the ECM and then it is returned to you and you will be ready to enjoy your car again in a way that you probably did not before.

Further below you will find a drawing with the location of the ECM

The following are the most common symptoms, but there are more symptoms not listed here:

-Hesitation or harsh shifting, specially in 3rd gear
-Shifting erratically
-Harsh engagement in reverse, often slamming into the gear
-Sometimes it feels like it is braking by itself
-Rattling, clicking or weird noise coming from the front of the vehicle when the engine is on
-One day it magically works ok and the other day, all the issues are back
-Issues show up only when cold or only when hot
-When stopping in a red traffic light and start moving again, it feels very heavy or sluggish
-Check engine or trouble codes are not present in most cases
-If check engine is present, it gives P0750, P0753, P0755, P0758 or P1760 codes
-In many cases, lower fuel economy than before


This issue will also affect:

-The 2001, 2002, 2003, 2004 and 2005 MANUAL transmission Toyota Rav4 ECMs. The most common issue with manual transmission models is lower fuel economy, but will also cause some other minor issues.

-The 2001, 2002 and 2003 Toyota Picnic and Toyota Avensis ECMs.

Besides the 2001-2005 Toyota Rav4, we are also servicing the ECMs of Toyota Picnic and Avensis described above.

This is something to be treated with urge! This will happen to ALL 2001-2005 Toyota Rav4, Picnic and Avensis ECMs. Some will fail soon and some others may take some more time. It all depends on use, vibration, temperature, altitude, relative humidity of your area and several other factors.

Once the ECM starts failing, the automatic transmission starts to be at high risk of getting damaged by this failure. Are you wondering if your vehicle is affected by this issue? Did you know that about 246,000 Rav4 units are affected by this issue in the USA alone? We can expect a total of more than half a million affected units worldwide. Your vehicle will fall on this list if it is a 2001-2005 Rav4, Avensis or Picnic from Toyota. We have found that some late 2000 models are affected too, as it uses the same ECM.

Below is a partial list of the Toyota part numbers affected. This number is shown in the label of the ECM. If the part number of your ECM is not on this list, you may contact us to make sure if your ECM is one of the affected units.

"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."

"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"

"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."

Tonja Smith

"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 forge"
