At this point in the game, I would replace the ECT sensor and see if that eliminates your hard shifting after driving awhile. ATX uses ECT input to control trans shifting conditions during diffferent tempature ranges.....If you are only getting hard shifting after driving awhile, I would try this first.

Did you do a power flush after you replaced the valve body? If not I would have this done also.

I would also begin to suspect solenoid pack if the above does not work.....

Oh, yes have you ever replaced the TSS? If it is original, I would first replace it before anything else.
