Aftermarket manual valve bodys are mainly used to change shift pressures, shift speed, and shift points as you know...in the 6R80 ALL of it is done in the tune
I enjoy shifting myself, but more importantly to me i like being able to set the shift light 500rpm lower, etc and run the 6.80 class, 7.0 and 7.30 class.
If you buy the SCT ProRacer Package you can change your shift points all you like or you can have your tuner enable the options on your device to do the same. Can't help you on manually shifting it though
