i just had my tranny rebuilt and took it back for the 10 day check up . but prior to that it started acting up a little bit. so any ways they test drove it and then asked me if i changed my tps sensor i said yea before i rebuilt the engine. it was idling high so i changed it and the idle air valve. it idles fine now but that didnt fix the problem like they thought. it is still shifting funny and now i am wondering else it could be . i have a warranty on the rebuild so im going to take it back but i was wondering if it was something simple that i could fix. they acted like it wasnt a problem when i took it back for the check up so im going to take it back and drop it off anyways since i paid for it out of my pocket and it has a warranty .
