The idea behind Transgo and other kits was to speed up the shift event and have less overlap. This in theory minimized the time the clutch packs were slipping in a sacrificial manner. However this increases stresses elsewhere as the stored RPM energy had to be rapidly disipated. The guys at Hydramatic were the best in the business at programing-- balancing comfort, drivability, durability and performance. That is 4 vectors kind of like trying to have the old "balancing eggs on eggs" task work out. They were designed to shift seamlessly imperceptible under light throttle and firm as loads increased. If you think about it in an 11k vehicle the loads are always high as if towing. Also going to harder shifts is a bad idea with FWD where uneven traction surfaces can jerk you into another lane with hard shifts.
