Diesel engines
WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
- Install a new snap ring and make sure that the snap ring is fully seated in the case snap ring groove.
Diesel applications: Install a new flat snap ring so the tang ends are in the gaps to the right and to the left of the case spline as shown.
- Check the function of the reverse clutch by applying air to the correct passage (through the case valve body worm trail) for the reverse clutch.
CAUTION:
Do not apply air pressure to move the low/reverse piston without first installing the friction plates and the snap ring, or damage to the snap ring will occur.
