Outside of a few spragless TAs that Hy-Capacity had about 30 years ago, on ALL TAs the low side is driven by a mechanical clutch of some type, either a sprag, ramp and rollers, or a mechanical diode. If any of these TAs slip on the low side there is no adjustment that is going to correct the problem.
The spragless TA used the same clutch pack for both the high side and low side clutches. The control valve spool was reworked to allow for faster shifting between high and low range but there were not very successful because of the loss of power to the wheels when the shift was happening.

The first clutch pack is not released until the next is starting to engage. That eliminates the loss of power to the wheels during shifting.
