04 Pontiac Grand prix service shift system
8 Answers
Did it start doing anything weird? ie shifting hard, staying stuck in one gear, etc.
It's started to shift hard I put tranny fluid in and it eased up the other day the car just shut off on my husband on the highway then yesterday it said service shift system
I also have the traction control, check tire pressure, and check gas cap. Now I know the tires are at the right psi but it's still saying it. The gas cap I changed and it's still saying the same as well. Now The traction control there's this wire hanging from my passenger front tire almost like a sensor wire but I can't get it to stay in cause the clips are broken.
that wire would cause the traction and check tire, but gas cap and tranny wouldn't be affected. sensor in gas cap could be faulty or worn. as for the tranny it seems like it might need to be replaced if it is having those problems.
