Input Planetary Gear Set
WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
The input sun gear of the input planetary gear set is driven by the underdrive clutch. The number 11 thrust bearing is captive underneath the pinion gears and therefore cannot be removed.
