Transmission help

I've got a 1997 Chevy 1/2 ton pickup with an automatic transmission. The problem I'm having is that after driving a long distance, say 50-100 miles, it starts shifting really hard. It is just fine on the highway, but when u stop and start again at a stoplight, it shifts hard, mainly from first to second. it has done this before and after it has been rebuilt. And the dipstick shows that it is full of fluid. I don't have a clue about what the problem is. Any help is appreciated. Thanks.

Have it scanned for tranny codes, rebel; may be a simple relay or sensor problem (when the 4L80E in my wrecker starts doing that it's often an input speed sensor going bad).

Thanks for your help, but i have another question. Can u tell if there is a code thrown, such as the check engine light coming on, or do you just have to get it scanned to find out?

Depends on the code and the type of failure.A scan is the only way.
