Traction control light, rough shifting 2010 HHR
Hi New member.
2010 HHR. 2.2 flex fuel. 100K. I forgot it and let it idled for about an hour the other day before I drove it. So When I drove it after that is When the problem stared. (,probably not what caused it) When I accelerate it is fine but when I let off the gas it starts down shifting, sound like the transmission is destroying it's self. Traction control light comes on. If I drive slow the ecu flashes. Now it sounds bad when it up shifts also. Don't seem to make any difference if traction control is on or off.
I have searched this forum for hours. It's probably there, but I can't find it. Things I have tried. 1 disconnected battery twice. 2 had the local Chevy dealer read the codes. NO codes. Kicked the tires, and cursed at it.
