Input Shaft
WARNING: This page is about a different car, the 2013 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The input shaft is the main shaft splined to the clutch disc and turns the gears in the transmission.
The gears on the input shaft mesh with the output shaft gears and provide torque from the engine to the differential. 1st and 2nd gears are fixed and 3rd-6th gears are free to spin on the input shaft.
The input shaft has one roller bearing and one ball bearing.
