The TA clutch only has to hold the sun shaft stationary with relation to the carrier. So does the clutch carry 1/3 or 2/3 of the load?
To add more complications, there are two different gear ratios on the planetary gears.
Whatever the real answer is, the torque that the TA clutch has to control is much less than engine torque.
