ok,i have a 95 3000gt automatic.we replaced the end clutch but it still has no overdrive.park,reverse,neutral,all work fine,no slipping or anything.when you put it in low,2nd,or drive it seems like its stuck in 3rd gear.it doesnt shift and takes off slow and at 55mph runs around 3000rpm.i dont know what to check next.any help asap would be greatly appreciated.thanks

 

it could be your trans filters on too tight.

 

sounds like they didn't replace one of the seals. Those exact issues will arise if that seal is not replaced/installed.

 

what seals are you referring to?

 

in the transmission.

 

check all of your seals and make sure everything is snug not to tight
