Input Shaft

WARNING: This page is about a different car, the 2008 Mercury Sable, 2008 Ford Taurus X, and 2008 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.

The input shaft is part of the direct/O/D clutch assembly and is splined to the torque converter turbine and the center planetary sun gear. The input shaft transfers power from the torque converter to the rear planetary gearset through the direct (3, 5, R) and O/D (4, 5, 6) clutches and the center planetary sun gear.
