THIS FIX IS COURTESY OF EXPERT TOYOTA ED, HE IS A TOYOTA DEALER SERIVCE MANAGER, THANKS ED! There is a known issue with the 2005-2007 Corolla automatic transmission shift logic. The shift points may seem harsh, and the Check Engine light may be illuminated.
There is a technical service bulletin published (TC015-07) that will address and rectify this condition.
The diagnostic code P2716 will be stored in the computer memory. The procedure involves replacing the Engine Control Module (the computer) with an updated unit.
The repair is covered, under the factory warranty, for 96 months, or 80,000 miles, which ever comes first.
There is currently a recall going on for this problem. You can likely get your money back on the prior repairs as well. See this link http://www.toyota.com/recall/corolla-matrix.html. On the left-hand side, you can click to take you to put in your VIN and see if your vehicle is included. My 2007 vehicle IS included, and I just had the check engine light come on and have been experiencing rough shifting for about 6 months. When the light came on yesterday, it was extremely rough jerky shifting. The light went off today. Took it to Autozone and got same code P2716. Toyota has assigned me a case number, but I won't get a call back until Monday or by close of biz on Tuesday. This problem can cause your car to not start, or to shut down while driving. YIKES! The person I talked to at Toyota acted a little too nonchalant about the whole deal. Telling me to just wait for the call that I will get. She said most dealers would not have the part needed to fix this. According to what I have read. That is the reason why Toyota is not sending out the notification letters to the affected parties until mid-September. Check out all the info and good luck. I am a little bit p.o'd about this right now. - Natalie
You have an issue that Toyota knows about; there is a programming problem with the ECM in the vehicle, and Toyota has released a Tech Service Bulletin (TC015-07) to cure your problem.
You probably have a DTC code of P-2716...The ECM needs replaced with an updated unit.
PLUS: this repair should be covered for 96 months of use, or up to 80,000 miles. The replacement ECU will be installed totally for free. Call your local Toyota dealer & get an appointment.
