It shifts ok except after it has been on the freeway or highway for awhile, or kick it down a gear. After it has kicked down the up shift is like it has a very hard shift kit in it. Even if you don't kick it down, when you get off of the freeway and stop it starts off and shifts thru the gears as if it has some kind of racing shift kit. After you stop and turn the engine off It will shift ok again. ( Needs to sit for a few minutes. Can't just turn off and re start. ) Doesn't happen all the time but does more then doesn't. Trans and engine temp seem fine...... ANY IDEAS ????????

 

Are you getting any codes?
