For the following rework procedure steps, refer to Disassembly and Assembly, UENR0125.Start by:
Remove the gear pump. Refer to Disassembly and Assembly, "Gear Pump (Torque Converter and Transmission) - Remove"
Remove the torque converter housing. Refer to Disassembly and Assembly, "Torque Converter Housing - Remove".
Disassemble the planetary. Refer to Disassembly and Assembly, "Transmission Planetary - Disassemble".
Perform Step 12 - Step 21.
Clean and inspect all parts. Replace the additional parts that are listed in Table 1 if a transmission failure occurred as a result of the loose screw.
Remove 263-2847 Manifold (Step 27) and clean threaded holes thoroughly prior to installing new screws.Reassembly:
Reassemble the planetary. Refer to Disassembly and Assembly, "Transmission Planetary - Assemble".
Reinstall 263-2847 Manifold (Step 44).
Step 50 - Insure holes are aligned. Install 270-9442 Screws and tighten uniformly around or in a star pattern, turning each screw no more than one complete turn at one time. Torque 270-9442 Screws to 12 3 N m (106 27 lb in).
Continue with Step 51 - Step 59.
Reassemble the torque converter housing. Refer to Disassembly and Assembly, "Torque Converter Housing - Install".Note: May be necessary to rotate the converter during assembly to ensure that all splines for clutch #1 and clutch #2 are aligned.
