Having problems with your 1997 Pontiac Sunfire ?

Sun I have a 2005 sunfire and everytime my trac off comes on my tranny starts to shift hard. So far i changed out my tranny for a new one and it's still the same. so i bought a new PCM and had it reprogram,but guess what?? It's still the same!!! So i changed the fuel pump,fuel filter,and last but not lease the intake air temp sensor.That helped for awhile then the trac off started coming on again so i don't know what is wrong with it!!! I gave up hope for it. someone told me it might be the cran

Answers :

For some reason the traction control is being told to be turned off, this could be for a number of reasons. Check the coil packs, they are know to go bad, but you should at least have the computer scanned for faults, it can save you a lot of money, and possibly direct you in the right way. The trac off is probably not causing your problem, the problem is probably causing the trac off, if ya follow me.
