Does it only shift hard on the 1-2 shift or all gears upshifting and downshifting and engaegements from park to reverse or drive? Is this the smaller AODE/4R70W trans or the larger E4OD trans?
Customer: replied 2 years ago.
it dose not slam in upper gears , down shifting not at all , its 1/2/d/od,no slam or clunk comeing out of park,its got a 5.8L 4x4 ext cab
Expert:  HDGENE replied 2 years ago.
Ok this should be an E4OD model with that drivetrain. Most likely an internal issue with the trans. the overdrive/coast clutch planteary is a weak leak due to issues with the trans slipping and running hot, its right behind the trans oil pump. Once things get hot, you have increased clerances and it engages hard. Will most likely be going internal to the trans or doing a replacement.
