2004
GM
Grand Prix
3800
250,000 km
Just purchased , loosing up as driven must have sat or at least not pushed hard lately.
Surging of power when slightly accelerating . Notice on uphill grade with cruise set.
Mechanic tested cold an said transmission major issue.
Drives nice . Seems less prevalent when hotter ?
No codes except gas cap P0455 ( large leak ) not found cause yet.
Any suggestions would be welcomed .
Thank You
