4.
Assure that all new service parts are used. If the transmission is equipped with the new oil pan and bolts, you should need only a new gasket. If the
transmission is equipped with former parts, use the following procedure:
A.
Remove the oil pan.
B.
Clean the transmission case to pan mounting surface with solvent and visually inspect the surface for damage and/or the presence of RTV
sealant. Be certain to remove all RTV sealant from the case to pan mounting surface.

C.
Replace the former oil pan (Figure 1) with service package number 8639907.
NOTICE:
(A) Do not use RTV with the new parts.
(B)
When replacing the oil pan, use a torque wrench to tighten the bolts to 11 N-m (9 ft.lbs.) then retorque all the bolts a
second time to the same specification. (This retorque is important because the gasket material relaxes after the initial
tightening.)
