FORD MUSTANG 2003 Workshop Manual

Assembly
1. CAUTION: Before beginning assembly, carry out and inspect the following:
When building up subassemblies and assembling the transmission, ALWAYS use new
gaskets and seals.
All fasteners must be tightened to the torque specification indicated. In addition to
appearing in the section, the necessary torques can be found in the General
Specifications Chart.
When building up subassemblies, each component part should be lubricated with clean
transmission 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 buildup 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.
Install the valve body cover plate. 1. Position the valve body cover plate gasket and cover plate.
2. Install the two guide pin bolts.
3. Install the bolts.
2. Tighten the bolts in the sequence shown. Klj . 5 ba
