auto tranny thumps into place
MY 2002 buick regal has started thumping into gears after about 15min of driving. I dont drive for more than 15min most of the time but when i do its annoying lol. IS there an additive I can use to fix this or will i need to replace my tranny?

Re: auto tranny thumps into place
Welcome to AF.
It would help to post your mileage on transaxle issues. Does this feel more like a harsh upshift? If so, a common problem is the PCS (pressure control) solenoid causing abnormal line pressure. Get it scanned with a trans capable scanner/scan tool and see if a P1811 (max adapt, long shift) DTC is stored.
