Hey Guys. Wanted to see if you can help me diagnose the issue I am having.

I have a 2002 Tahoe LS V8 FFV 5.3 Liter.

I noticed the a month or so ago, after getting off the interstate, that the transmission was starting to hard shift as I began to accelerate after stops. Then as I paid closer attention to it, if I stayed on side roads and not go up above like 55mph, It never had an issue with shifting and ran like a top.

I got off the interstate over the weekend and it started to hard shift again. So, at the light I turned off engine and turned it back on and when I accelerated it, it shifted normally.

As I ran errands this weekend, I kept checking different driving routes and turning the engine off and on after interstate rides.

Its quite bizarre.

Anyone have any clue as to the problem? The check engine light is on but the code is reading hard shift only.
