Caution Do Not allow valve body plate to separate from upper valve body during removal or check balls and strainer may fall out

Inspection

1. Clean all parts in solvent. Dry with compressed air. Ensure all valve body passages are clear. Ensure strainers are not damaged or clogged. Inspect valves for scoring or roughness.

2. Ensure valves slide freely in bores. Inspect valve springs for damage, squareness and collapsed coils. Measure spring free length. Replace spring if not within specification. See appropriate VALVE BODY SPRING SPECIFICATIONS table. Ensure valve body springs correspond with appropriate valve. Ensure

Reassembly

1. Coat all components with ATF. To reassemble, reverse disassembly procedure. Ensure check balls in upper and lower valve bodies are installed in correct locations. See Fig. 57-Fig. 61 .

2. Position NEW No. 1 gasket, plate and NEW No. 2 gasket on upper valve body. Install spring and check valve. See Fig. 62. Ensure oil strainers are installed on No. 2 plate. See Fig. 63. Place lower valve body on upper valve body with plate and gaskets. DO NOT let components separate. Align each bolt hole in valve bodies with gaskets and plate.

3. Install and finger tighten bolts in upper valve body. Ensure proper bolt length is used. See Fig. 64 or Fig. 65 . Tighten bolts to 56 INCH lbs. (6.4 N.m). Install oil strainer, pressure relief valve and solenoids (as applicable). Install manual valve and detent spring. Tighten bolts to 89 INCH lbs. (10 N.m). Ensure manual valve moves freely.
