Do you own a 2001-2005 Toyota Rav4 and are having issues with the automatic transmission?
If you own a 2001-2005 Toyota Rav4 and are having problems with the automatic transmission like for example, the transmission acts erratically, or you are experiencing loss of power when accelerating, or if it is starting (launching) in any gear other than first gear (usually in 3rd gear), or engaging harshly when putting it in reverse, or if it is slipping from 2nd to 3rd gear, all these issues are caused by a defective ECM (Engine Control Module) and we have the perfect 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.
After you complete the order, you mail us your defective ECM, we repair, reprogram and test it and then it is shipped back to you. Our turn around time is only one business day. International orders are welcome.
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). It also covers the Toyota Picnic and Toyota Avensis models of the same years (2001-2005).
NOTE: In some cases, this will also affect the 2000 Rav4 models. This will only depend on the ECM part number installed in your rav4. Please look at the affected ECMs list elsewhere on this page. If your ECM is not listed, please contact us for more information.

-WE ACCEPT INTERNATIONAL ORDERS
The following are the most common symptoms shown for this issue with the ECM. You may experience only one or several of these symptoms at the same time and some may or may not ever show in your case. If you have experienced at least one of the following, then the ECM needs service ASAP:
- 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 shows 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. Consumes more gas than usual
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 also take care of 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.
ECM Part Numbers Affected
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.
For returning the repaired ECM we use FedEx and in some cases, USPS. FREE fast return shipping (2 business days) is offered to locations in the USA, including the 48 contiguous States, Puerto Rico, Hawaii, Alaska, Guam, American Samoa, 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 them.
Faster (paid) shipping options are also available for both, USA and international locations and can be calculated from your shopping cart with the provided shipping calculator. Just “add to cart” the service and the calculator will show on the next page.
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. This way, future problems, related with 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 first repair the circuit and replace any needed parts.
- Second, we reset the transmission adaptation memory so it starts relearning from zero when it is installed back in the vehicle. If your vehicle is equipped with the immobilizer security system, we reset it too to ensure that the engine will start when it is installed back.
- 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 (only for USA models).
- 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 when it is shipped back?
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 notify you of the shipping details and the tracking number.
If you do not receive an email from us, it probably is in your email’s spam folder. We will also try to notify users through SMS text messages, but for this, please enter your mobile phone number when doing the order. It is also a good practice to create an account with us when ordering, instead of ordering as a guest. This way you will always have available a copy of any message sent to you by email when you log into your account with us.
For more questions, please see our FAQ section in the “FAQ” tab on top of this information section or feel free to contact us any time through the contact form on this page. We will be more than glad to help.
We always stand by our customers and always try our best to help if you encounter more problems with your ECM, even if the problem is unrelated to our service or of the warranty time has passed. For our warranty on this service, please check the “Warranty” tab on this page.
Removing the ECM from your vehicle:
Tools you will need:
- Short #2 Phillips screwdriver (stubby)
- Regular #2 Phillips screwdriver
- 10MM Socket Wrench
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!
