P0700 Chevrolet -

Question

I have a 2010 Chevy Malibu LS with a 2.4 liter engine. When the car is cold the transmission works just fine. After it warms up the car looses power. It will still drive but I have to mash the gas peddle and it takes quite awhile to get up to speed, and then the transmission isn't working properly. The engine light is on and I have come up with engine code PO700. I know that it means possible problems could be, transmission control module or transmission solenoid. Has anyone had this identical problem with there 2010 Malibu with 2.4 liter engine? I am willing to purchase a new TCM just to see if that fixes the problem as well as replacing the solenoid. I have been researching to find out how to replace the TCM but coming up with nothing. Can someone please help me.

Answer 1

P0700 Transmission falut detected MIL light requested

This code is only infomative , there should be other code with this beside P0700. The ECM can also store this code as well as the TCM. If the transmission had a solenoid fault it would set a code along with P0700. this code can also set when there is a communication problem which would set a "U" code. Replacing the TCM will not resolve any solenoid or internal transmission malfunction. check for other code that will set.
