Got a 2002 GTP all unmolested bone stock.... This is my commuter car to work that's been babied, I just did $2700 in maintainence and after a trans flush I am noticing some converter slippage. Normal driving it doesn't do it. Seems to be only when taking off going up hill and its when it locks going into drive.... If you let off the throttle then get back in it it quits..... I've owned the car since 40,000 and it has 159,000 on it now.... Like I said Ive never even had the pedal to the floor..... Any idea here? I'm gonna call the shop in the morning and ask if dextron 3 was put back in it..... Any sensors on the trans that maybe could have something to do with this?
