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.

"Richard- I just want to say GREAT SERVICE! I must say that I was a little nervous sending my ECM to Puerto Rico to be repaired and other people looked at me like I was crazy, but I really believed that out of all your competitors out there, that you provided the best service. My wife and I had just purchased our 2003 RAV4-L and the very same day we had transmission shifting issues, then they only got worse after a couple of days. When the check engine light came on I took it to an auto parts store to have it scanned and it came up as the solenoid in the transmission, so I looked up the code on the internet and read lots of things about the problems and recall. This research led me to your site and after reading other people's reviews and stories, I knew that I should send it to you. Thank you soooo much for saving me a ton of money! - David (GA-U.S.)"

"Very Good service! Good job guys! We are from Australia and were faced with a faulty ecm for the rav 4 2003. The first mechanic said they could get it fixed for $800. We got a cheaper quote of $385 from a place in Brisbane but they sent it back saying it was "Non Serviceable". So anyway we were then faced with the option of buying a new ecm ($700)- but then it would eventually fail again, buying a "repaired one of ebay ($500) - But the repair offered on ebay is only a temporary fix, buying a second hand one ($300) -not a good idea as it will fail again or THE BEST OPTION - To get the ecm properly repaired by Richard! So yea Purto Rico?? But yes it came back good as gold and Richard helped us out every step of the way. The problem it seems is that because of the design the ecm's they overheat and some of the components on the circuit board fail then they send false signals to the transmission to change gear, this will ruin your transmission. The service on ebay and you tube only rep"

"PHENOMENAL - Like others, I was leery, but no need. I had just purchased a used 09 Rav4 for my daughter for school clear across the country and less than a week before she was to leave I was informed that the transmission was acting up. Took it to the shop who checked it out before I had purchased and was told quite the line of b.s., so I started researching and wound up here. Took the Rav to a trans shop had 'em drop the pan to make sure there was no metal parts - there wasn't, so I had it serviced and sent the ECU off to Richard Rodriguez in Puerto Rico, not really knowing if I'd ever see it again. He received it Wednesday afternoon and I had it back on Thursday at 10:30 AM! The test drive after initial install showed evidence of improvement within roughly a five to ten minute "learning curve" and it was decided that the cross country trip would happen. I am extremely pleased to say that the 2,400 plus mile trip was a complete success! The factory ECU is right at $1,200.00 not i"

"My daughters 2001Rav4 was not changing gears correctly.the transmission was hanging up between gears and staying in 3rd gear. I found the Other Deal online and set my ECM off to Richard. he promptly returned it to me, repaired, I installed it, and the car works flawlessly. Thanks Richard for super job I am very satisfied.

"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....Nicholas"
