..."limp home" mode? my 96 ss only uses reverse and third and i cant figure out why. ive taken it to autozones and advance autoparts and none of there diagnostics tools even pick up anything as if my computer doesnt work. ive baught a new computer but I'm still stuck in limp home mode. does anybody know of any other reasons for why my transmission would stay in that mode? its a v8 lt1 350 with a obdII computer.

the exhaust system could be clogged, most probably the catalytic is plugged up. to check unhook the exhaust from manifold and see if vehicle runs nomal. catalytic went bad on my 02 impala and this is how I figured it out

time to bring it in to Mr.GoodWrench

knock sensor
low oil
cam sensor
bad engine/body ground
shorting wires.

I would say take it to a real shop that has a real diagnosis machine that can read and clear codes.

The parts store is JUST a reader - and not that great.

You probably need a new transmission
