i took my car into get the transmission looked at. it is still under warranty so it needed to be done. it shifts hard sometimes and hesitates sometimes but only sometimes. it could happen one day and then not the next day. i have a Jet Module and the dealer said that the wires connected to the MAP sensor and the TPS is defect for some reason and is throwing codes. they are saying because of that the transmission is shifting hard and sometimes hesitates. i don't think that is right but i know you guys know more about this than me. thanks.

I have the similar problem. I am taking it in for service, but I just wanna know what's going on.

i have a problem with mine wanting to hesitate on the 1-2 shift. who knows, but i don't want to pay a big bill to get it fixed.

Most likely it's some electrical problem since our tranny is electronically controlled. If the tranny itself is worn out, it would slip ALL THE TIME.

maybe sparking plug wires? i heard this happening with that, i think happens on mine too, but i got some MSD on the way :D

Things like line pressure, tranny fluid, solenoid can go wrong.
