Steps Before Assembly

NOTE: MERCON Automatic Transmission Fluid is being replaced by MERCON V as a service fluid.

NOTE: Before beginning Assembly, perform/inspect the following:

- All fasteners must be tightened to the specified torque indicated in the assembly procedure.
- When building up subassemblies, each component part should be lubricated with clean Motorcraft MERCON or MERCON V or equivalent meeting FORD approved fluid. It is also good practice to lubricate the subassemblies as they are installed in the case.
- Needle bearings, thrust washers and seals should be lightly coated with petroleum jelly during subassembly build up or transmission assembly.
- Many components and surfaces in the transmission are precision machined. Careful handling during disassembly, cleaning, inspection and assembly can prevent unnecessary damage to machined surfaces.
- When building up subassemblies and assembling the transmission, ALWAYS use new gaskets and seals.
