Steps Before Assembly

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

^ All fasteners must be tightened to the torque indicated in the text. In addition to appearing in the text, the necessary torques can be found under Specifications.
^ When building up subassemblies, each component part should be lubricated with clean Motorcraft MERCON Multi-Purpose (ATF) Transmission XT-2-QDX or equivalent MERCON approved fluid. MERCON(R) automatic Transmission Fluid is being replaced by MERCON(R) V as a service fluid, as per TSB 06-14-4. 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.
