This issue is simply annoying at the beginning, then it gets worst and finally, it ends up damaging the automatic transmission (A/T) in the long run. Even accidents have been reported because of this issue, when the transmission suddenly shifts down to first gear by itself at highway speeds. It is like suddenly applying the brakes!

The mechanic will always tell you to repair the transmission, but the first approach is to service the ECM, because in 99% of the cases, the problem is only a faulty ECM (Engine Control Module), a.k.a ECU.

The following are the most common symptoms:

  • Erratic Shifting.
  • Transmission slips in any gear, but mostly, from second to third gear.
  • Starting in 3rd gear, making it move sluggishly even at high RPMs.
  • Hesitation when engaging in any of the gears.
  • Rattling noise coming from the front area when the engine is running.
  • The feeling of applying the brakes by it self in occasions.
  • False solenoid codes; P0750, P0753, P0755, P0758 and/or P1760.
  • The codes above not always show (DTC codes). Sometimes it fails with no codes at all or no check engine light.
  • Engages hard in reverse with a "bump" or takes time to engage.
  • Symptoms are intermittent. Sometimes symptoms only show up when warm or when cold and sometimes symptoms do not show at all.
  • One day it runs OK. All the symptoms magically disappear, but the next day, all or some of those symptoms are back.
  • In many cases, lower than normal fuel economy.


It is been informed that around 235,500 RAV4 models in USA might be affected with this issue about the ECM. That is; 77,100 units from 2001 models, 87,600 units from 2002 models and 70,800 units from 2003 models. That's almost 1/4 million units in USA alone! There is a countless number of the same 2001-2003 units affected in other Countries that are not included in the 235,500 units. The total can easily be 2 or 3 times that quantity of ECMs, getting close to a million units.

It is a fact that sooner or later ALL these 2001-2003 Toyota models will be affected with this issue, unless the ECM is PROPERLY repaired or replaced, of which, we recommend the repair option, as many new ECMs, besides being expensive ($800-$1300), are failing again after some time of being replaced. Used ECMs are out of the question. They will fail immediately or soon after installed.


We are offering the service of repairing your vehicle's ECM for getting rid of this issue for good, before it damages your transmission. This is a permanent cure and it is available right now, right here! We have identified the causes of this issue and have worked with it for nearly 5 years, as today, Feb. 12, 2015. Our repair service does not only fix the problem, but also prevents it from happening again.

When your already serviced ECM is returned, it will be ready to be installed and used right away ("plug and play"). No programming will be needed and no trips to any dealer. TAKE ACTION NOW! Don't damage your transmission by driving your vehicle with a failing ECM! A transmission repair or replacement job will cost you anywhere from $3000 to $5000 from your hardly earned money!

This service covers the 4WD and 2WD automatic 2001-2003 Toyota Rav4, automatic 2001-2003 Toyota Picnic and automatic 2001-2003 Toyota Avensis Verso. The manual transmission (M/T) 2001-2003 Rav4 is covered too. There are minor issues like low fuel economy (low mileage) and some other issues in the manual transmission models.

THERE ARE REAL AND JUSTIFIED REASONS - You should consider that if your transmission gets damaged by using a failing ECM, it will cost from $3000 to $4000 to repair or replace it! It is up to 20 times the average price for rebuilding your ECM with us!

2001 2002 2003 Toyota RAV4 ecm ecu tcm repair service

Where is the ECM located in my RAV4?

Location of the 2001 2002 2003 Toyota RAV4 ecu ecm tcm computer

Toyota RAV4 ECM repair FAQ

What do you do? Do you reprogram or repair the ECM?

Both. We repair the circuit of the ECM and then reprogram the ECM. A reprogramming alone will not fix the transmission issues. The reprogramming is done to the transmission adaptation tables, which are located in the memory of the ECM. The repair process includes replacing any damaged electronic part and reconditioning of the whole circuit, to avoid this from happening ever again.

I have seen a lot of places over the Internet offering this same service lately. Why choosing you?

I need to first point out that all other places are not offering "this same service". We differ from them in that the ECM is not only repaired, but completely rebuilt. We cover what our competitors do not. For example, the common low fuel economy or low MPG issue is also covered in our service. We have identified many potential problems in these ECMs, besides the transmission harsh shifting issues.

We constantly receive ECMs that were previously serviced by other shops, sent to us by unhappy customers in a second attempt to fix their ECMs. Contrary to our competitors, ECMs that we service DO NOT come back after a year or after months, to be serviced again.

But to answer the original question, Why choosing us? Because ECMs serviced by us, does not fail again. We fix the problem for good. You will see unsolicited reviews left by some of our customers from all around the globe, in our Facebook page.

May I have a copy of the bulletin distributed by Toyota about this?

Sure! Below you may download the official Toyota documents from our other website (


and below, is the warranty extension bulletin issued to service managers and warranty administrators:

2001-2003 Toyota RAV4 Warranty Enhancement

Is it hard to remove the ECM from the vehicle? Is it a mechanic needed for the job?

A mechanic is not needed to remove the ECM. It is a matter of removing several bolts attached to 3 brackets that hold the ECM to the vehicle's chassis. For doing this, a short Phillips screwdriver and a 10mm socket head wrench will be needed. Other than that, you will need to disengage the glove compartment (2 philips screws) and disconnect the 5 white connectors attached to the ECM, by simply pushing a clip on each connector and pulling it out.

Do I need to disconnect the vehicle battery before uninstalling or installing the ECM?

It can be disconnected if you feel more secure that way, but it is not necessary in these models.

My ECM is not on the shown list. May I send it to you?

If it is a 2001, 2002 or 2003 Toyota Rav4, Picnic or Avensis, either 4x2 or 4x4, then yes, and we will fix it for you! There are more ECM part numbers affected than the ones listed on our page.

Will my RAV4 pass the smog test (emissions test) when doing inspection of my RAV4 if I get this service?

Short answer, YES. Long answer, it is actually the other way around, if the ECM issue caused somehow to fail the smog test, then after repaired it will pass the smog test without a problem. If it passed the emission tests before the problem showed up, it will then pass the test after the service more easily. This service will not alter in any way the function of the engine. We have even received reports of the vehicle performing and shifting better than ever before.

What are the engine specifications of these RAV4 you are servicing their ECMs

Engine is 4 cylinder, 2.0L, either the 1AZ-FE or 1AZ-FSE Toyota engines.

Do I need to program or do anything else that require a trip to the dealer in order to use my repaired ECM?

No, not at all. Your ECM will be "plug and play" when you receive it. That means that you just reinstall it in your RAV4 and it will be ready to use. No programming, no trips to any dealer and no towing your RAV4 to the mechanic. You will start enjoying your new-again RAV4 as soon as the ECM is serviced and reinstalled.

People tell me that these ECMs will lock once serviced and will need to go to the dealer so they can fix that. Is it true?

Short answer, NOT with us. Detailed answer, Yes, it might happen if the ECM has the immobilizer system enabled and the technician who work with the ECM does not do the job correctly or does not know how to handle it (common in other shops or "Companies").

We always prepare our customers' ECMs so they are ready to start the engine as usual when installed and can be used right away. If your ECM has the immobilizer security system enabled, it is not a problem for us. We will know just by reading the memory of the ECM as soon as we receive it and will program it accordingly, so it works with your keys and only with your keys.

You charge an amount for the job, plus shipping. How does shipping work?

The shipping fee we charge is for covering return shipment. That fee will pay the shipping service used when we send the repaired ECM back to you. Shipping it to our location, must be done by customers on their behalf.

I have more than one ECM. Do you offer combined shipping or any other discount?

Yes, email us the details so we can make an offer. Basically, we will ship up to 3 ECMs for the same shipping charge of 1, if shipped to USA. It would be up to 2 ECMs for the same shipping charge of 1, if sent out of USA.

If you are a dealer or a mechanic and will eventually order more services, the second service will have a job rate discount of 25% of the first order. If more than 10 service orders are done, we will offer you a nice price for the 11th and all subsequent orders.

What warranty do you offer and what does it cover?

The warranty in months is specified elsewhere at the top of this page, near the "Add to Cart" button. The warranty we offer, covers the repair job itself. During the whole warranty period, in the rarest occasion that your ECM fails with the same symptoms, we will take care of it and if it is the same problem we worked on the first time, we will fix it at no cost.

About shipping, we must clarify between problem and symptoms regarding this warranty. The symptoms are what you are experiencing and the problem is what causes the symptoms. In the event that you send it back because the symptoms are the same, but we find out that the problem is different after checking it out, we can not cover shipment from your location to ours in that case. We of course, will ship it back no charge after fixing it. If on the other hand, the symptoms are the same and the problem is the same too, then we will cover shipment both ways. How? When the ECM is fixed, we will ship it back on our account, as normally done, and will also refund what you spend in shipping your ECM to our location.

Note 1: When shipping back ECMs fixed in warranty, we will use the most economical way, being USPS Priority in shipments to USA, or FedEx Economy in shipments to other Countries.

Note 2: The above warranty coverage will be valid as long as (1) the warranty seal(s) is not removed or tampered, (2) it was not caused by an external cause, like (a) a short circuit in the vehicle's circuitry, (b) if the ECM was used in the wrong car model, (c) if the ECM fell into the water or any other liquid, (d) if the ECM fell down from a considerable distance to a hard surface affecting or damaging the circuit or (e) if the ECM was smashed.

How much time will this service take?

We generally take only one business day. On high workload days, we might take up to 2 business days. The rest of the time it will take, will be shipment transit time, which will generally be 3 to 5 business days if mailed in the United States using USPS Priority Mail or 1-2 days if using USPS Express Mail. If FedEx is used, it would be next business day in USA destinations. FedEx on international locations (out of USA), would take 2-6 business days.

How does this service work? Do you send an ECM after I pay?

No. Right after you order the service, we will be expecting your ECM to arrive any time to our location, so it can be repaired, reprogrammed, tested and then shipped back to you. You may even send your ECM before payment is done, so some time is saved. In that case, you will receive an invoice (payable online) as soon as the ECM gets here.

Is the ECM the same as ECU?

Yes, it refers to the same automotive part. ECM stands for Engine Control Module and ECU stands for Engine Control Unit, but refers to the same device.

If the ECM or ECU is "Engine Control Module" or "Engine Control Unit", why should I send it if the issue is not with the engine, but with the automatic transmission?

In the case of the automatic 2001-2003 Toyota RAV4, Picnic or Avensis models, the ECM controls both, the engine and the transmission. This is different from other automatic car models, where there are two separated electronic modules, one for the engine and another for the transmission, called in many cases "Transmission Control Unit" (TCU) or "Powertrain Control Unit" (PCM).

Do you offer this service to any country?

Yes, we repair RAV4 ECMs from all around the world. All Countries are welcome!

How should I pack my ECM when shipping it to you?

Just send it in a small box, wrapped with some paper, plastic wrap or any packing material of your choice (used newspaper is fine). Sending it in a bubble padded bag is ok too. The construction of this ECM is pretty tough and withstand moderate impacts. So far, all incoming ECUs have arrived OK, even those that came packed in a plain bag or large envelope.

My RAV4 has the immobilizer system enabled. Can you still service my ECM?

Sure! You will have no problems with the immobilizer or with starting the engine with your keys (transponder keys). It will be ready to use as soon as you receive it.

I depend a lot of my RAV4. What could happen if I keep using it like that while I have the chance to send it to you?

Using your RAV4 with a failing ECM may cause the transmission to have an internal failure and then, the ECM and the transmission will both need service. This is something to be treated with urge once your vehicle starts showing the symptoms mentioned above in this page.

Is it really the ECM and not the transmission? It feels like the transmission is really broken! Sometimes I think it is falling apart as I drive.

In very few cases, the symptoms are caused by a bad transmission, unless it has been used and abused with a failing ECM. When the symptoms show up for the first time, you are still on time. Repairing or replacing the ECM is always the first step to take. It all begins with a faulty ECM and not otherwise. Fortunately, it is also the less expensive step.

Is there a chance that the transmission could be damaged besides the ECM?

Yes. Please see the answer of the previous question above. Our experience is that in most of the cases, and we are talking about 99%, the problem is only a faulty ECM. It is very important that once the symptoms show up, you stop using your RAV4 and either replace or repair the ECM.

"Too bad we can't post 10 stars. You are the bomb!!!! I sent it on Monday and got it back on Friday. It ran rough for about 15 minutes ( to learn the transmission codes), then it started shifting like a champ. You are the best. Many Thanks."

"I own a auto repair shop in the state of Iowa. I read other reviews of pcm shops all had bad press, except for other no bad press found. I sent it to Puerto Rico. Richard always emailed and kept me updated. My friend took her rav to a really good tranmission shop to have the fluid exchanged, per my reccomendation. After they flushed the trans, the thing shifted terribly trying to ripitself apart. I sent in the PCM, turn over was fast and it fixed the problem with the Rav4. I must say I was skeptical at first. I will otherdeal first from now on. Thanks Richard, you are the man and your people too."

"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"
