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

Torque Converter
1. A new or remanufactured torque converter must be installed if one or more of the following statements is true:
zA torque converter malfunction has been determined based on complete diagnostic
procedures.
z Converter stud or studs, impeller hub or bushing are damaged.
z Discoloration (due to overheating).
z The torque converter is found to be out of specification when carrying out one of the
following torque converter checks:
„One- Way Clutch Check
„ End Play Check
„ Stator to Turbine Interference Check
„ Stator to Impeller Interference Check
„ Torque Converter Leak Check
z Evidence of transmission assembly or fluid contamination due to the following
transmission or converter failure modes:
„Major metallic failure.
„ Multiple clutches or clutch plate failures.
„ Sufficient component wear which results in metallic contamination.

Torque Converter Cleaning And Inspection
1. If a new torque converter is being installed, continue with Substep 2 of Step 2.
2. If a new torque converter is not being installed, the following procedures must be performed: 1. The torque converter must be thoroughly cleaned.
„Torque converters with drain plugs can be cleaned by using a suitable torque
converter/fluid cooler cleaner.
„ Torque converters without drain plugs can be cleaned by hand. Partially fill the
torque converter using only recommended transmission fluid for the applicable
transmission. Hand agitate the torque converter and then thoroughly drain the
fluid. Refill the torque converter with clean automatic transmission fluid specified
for transmission, and reinstall.
2. All in- tank and auxiliary coolers must be thoroughly cleaned by forward and backward
flushing. For additional information, refer to Transmission Fluid Cooler — Backflushing
and Cleaning in this section.
3. All cooler lines must be thoroughly cleaned by backward and forward flushing. For additional information, refer to Transmission Fluid Cooler — Backflushing and Cleaning
in this section.
4. All Cooler Bypass Valves (CBV), if equipped, must be thoroughly cleaned.
5. Carry out the Transmission Fluid Cooler Flow Test. For additional information, refer to
Transmission Fluid Cooler — Backflushing and Cleaning in this section.
6. If the transmission cooling system fails the Transmission Fluid Cooler Flow Test, a new fluid cooler, cooler bypass valve, and/or cooler lines must be installed. For additional
information, refer to Section 307 - 02 .
7. If new coolers are to be installed, use only factory approved service parts.
