15. This in-house transmission dynamometer is how ATS knows that every transmission that leaves their facility is working correctly. The dyno's engine spins the input shaft, and a brake system on the tailshaft creates load with resistance. As the load is applied, Bob Wichman shifts the transmission through each gear and internal pressures are measured at each point. This is done to make sure that the shift valves and gear pack application (on and off) are happening as they should be.
