Hi all,

I came across this website after Googling a P0755 code. I wish I had done that sooner.

I bought the 2001 Rav4 with 160k miles on it. Couple months later, I had some problems, and the dealer charged me $3,000+ to replace the VVT, catalytic converter, and ECM. The first ECM was bad and he replaced it with another. Well I started having these transmission shifting problems with difficulties switching from 2nd to 3rd. This happened very rarely so I thought nothing of it. And the car was in the shop for 2 months and I didn't want to complain. I thought all was good. Well, the shifting problems have gotten way worse in the past month. I got a check engine light with a P0755 code and my mechanic says my transmission solenoid needs to be replaced (and God knows how many more thousands that is going to cost). I don't believe him because he's a general mechanic and not a specialist who knows about this 2001-2003 Rav4 ECM issue. I am worried that the transmission is now genuinely bad, due to driving on what I think is an ECM. I couldn't get out of first gear driving home (~25 miles) so for now I am not driving the car.

Issue is it's the weekend. And I desperately want to replace the ECM. Advice?

I looked at Circut Board Medics for $200 to repair the ECM and Module Repair Pro for $139... Which do you think is better, faster, and more reliable? I also read the main transmission/ECM thread. I desperately need this fixed otherwise I can't go to work next week.

I'm very sorry this is happening to your Rav, but it sounds like the same old ECU problem, striking again. Here is the longest, most detailed discussion about this issue, in which you are more likely to find solutions, more quickly:

http://www.rav4world.com/forums/178-recall/70278-ecm-transmission-problem-2001-2003-rav4.html

That thread covers 8 years of people having this issue and is 52 pages long (that is how well known, unfortunately, this boondoggle is). There are some remedies in there, such as replacing the ECU as you mentioned, or sending it away for service. Look through that thread and see if there is some information you can use right now.

I would recommend that you don't drive it until you get it sorted out! This just happened to few months ago to my sister's '01, which she has owned since it was new. Long story short, it was a very quick failure and the transmission is now shot. She's given up on it, and is scrapping it. So, don't let that happen -- let the Rav sit until you get it fixed so that you don't damage the transmission.

My other sister's '01 was repaired for this issue in 2009, and has been running fine since. But at that time, the dealer told her she had to replace the transmission and the ECU entirely -- $4800!! It took a lot of effort on her part, but she did get Toyota to pay for it.

I'm sorry you're having this problem -- it really, really sucks and Toyota completely mishandled it. :(

I purchased a refurbished ECU from Module Repair Pro on eBay a couple years ago. Fast service fast shipping from what I recall took a couple days to ship, I'm in California. You'll be charged a Core but will receive a refund once they receive your old ECU.

Okay, I have an update. Last week I had access to my sister's '01 in California, which is the one described above in this thread. To make a long story short, she was told by the dealer that her Rav had terminal transmission damage AND engine damage, and needed a new ECU, transmission, and engine work for a total of over $4,000. They were able to make these determinations, apparently, even though they couldn't get it to start and didn't bother swapping ECU's on it. The Rav has just 123K miles and is otherwise in great shape and passed CA emissions.

I thought this sounded ridiculous, having read these many threads on rav4world about the ECU issue. Why didn't they at least try an ECU swap? Her Rav wouldn't get into any gear, under any circumstance, period. It was totally immobilized -- what does that sound like? She is ready to sell it for scrap, so I had free reign with it.

I followed the youtube video posted above, and went ahead and re-soldered the grounds and resistors on her ECU. I actually have two ECU's to work on, because my other sister's '01 Rav4 had been repaired back in '07 or '08 with a new ECU and transmission, and she still had her old, original ECU (she was able to successfully fight for Toyota to re-pay her even before the class action suit!). The old ECU is a different part number than the new ones.

I am a terrible solder-er and while none of my work was pretty, it was apparently enough to do something. I put the re-soldered ECU back in the white Rav4, and it started up and took any gear or neutral with the selector, which was a 100% improvement over its previous condition. Reverse was easy and strong, drive was fine in first and second gears, but she slipped getting into third. When I put her in 2nd, she zipped around totally normally. There was a hissing sound from the transmission side -- I'm not positive it was the transmission, but a little afraid that it might be. I didn't have a chance to drop the pan, but the ATF on the dipstick looked fine and I didn't see any metal bits.

So, my next action is to have the other ECU (the old one that I didn't solder) professionally repaired and re-flashed. The vendor I spoke with will replace all the resistors and re-solder the grounds, re-program the ECU with the new software, and then test the ECU in a 2001 Rav4 at their shop before returning it to me. The price is under $100 with a lifetime warranty, so I think its worth it and I'm sending if off tomorrow. I will update with the results in a few weeks and also name the vendor if everything goes well.

Wish me luck!

Its criminal what Toyota has done to customers.
Even more so that when the warranty was good. They didn't do the repair. But to save everyone an emotional rollercoaster... If you're not comfortable fixing it you're self.
I found a great guy on Ebay. He fixes you're ECU, doesn't send you a knock off. Its less thank a $100. But it takes up to 2 weeks. You mail yours to him. He fixes it and sends it back to you.

Ive posted his info in prior threads. Its working great, mater of fact it was working so good. the damn shift linkage now snapped. lol
Hence why i stopped by the forum. lol
If you need his info PM me..
Best of luck.
