sorry just need to be sure
are there any codes set in the computer at all history or current ?
when did this transmission start acting up how long after rebuild ?
usually when these will harsh shift there is some small debris in the transmission fluid that will usually stick the pressure control solenoid which will cause harsh shifting
the best action to take is to have the transmission fluid flushed with a transmission flush machine with cleaner once that is done see if it still does this if it does then removing the transmission side cover and replacing the pressure control solenoid in the valve body and the tcc solenoid
those things usually corrects this type of issue
how are you making out ?
