Forward Clutch (A)
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The forward clutch (A) connects the front planetary carrier to the rear No. 3 sun gear. This provides a gear reduction ratio of 1.52:1 from the input shaft to rear sun gear No. 3. The forward clutch (A) is applied in 1st, 2nd, 3rd and 4th gears.
Regulated hydraulic pressure from the regulator valve in the valve body pushes the forward clutch (A) piston against the forward clutch (A) pack to apply the clutch. The front planetary carrier and the rear No. 3 sun gear are connected as a result of the clutch being applied.
