i have a pontiac grand am 2001 and is automatic but is it it possible the transmission can under shift or skip a gear while its shfting ?
idk if a 4 cylender has 5 gears or not im dumb with cars lol but it feels like it skips a gear when shifting up because as im going it will go up to 2cd while im accelerating its like theres no 4th it drops acceleration i have to let off the gas and push it again to go in to over drive to get it up to speed and it vibrates when im in drive when im stopped any advice?
