20. Transmission Case Inspection

Transmission Case Inspection

Tools Required
^ J36850 Assembly Lubricant





1. Notice: Use J36850 or equivalent during assembly in order to retain checkballs or to lubricate components. Lubricants other than the recommended assembly lube changes the transmission fluid characteristics and causes undesirable shift conditions or filter clogging.

Remove the 2 case cover O-ring seals from the transmission case assembly. Discard the seals.
2. Inspect the transmission case assembly for the following:
^ Cracks
^ Porosity
^ Sharp edges
^ Connected passages
^ Excess gasket material left on any case surfaces
^ A loose, missing, or damaged identification label - nameplate

3. Inspect the bearing cup for the front differential drive pinion gear for damage. Replace if necessary.
4. Inspect the bearing cup for the front differential carrier for damage. Replace if necessary.





5. Inspect the spacer plate to case gasket for witness marks. The witness marks should be complete. Incomplete witness marks may indicate an uneven case surface or cross-channel leaks.





6. Notice: Refer to Fastener Notice in Service Precautions.

Inspect the fluid pressure test hole plug for damage. Replace if necessary.
Tighten the fluid pressure test hole plug to 9 Nm (7 ft. lbs.).
7. Inspect the fluid fill lower tube, seal, and plug for damage. Replace if necessary.
^ Tighten the fluid fill lower tube assembly to 20 Nm (15 ft. lbs.).
^ Tighten the fluid fill lower tube assembly plug to 11 Nm (8 ft. lbs.).





8. Inspect the bolt holes for thread damage. If necessary, repair any bolt holes.
9. Inspect the retainer ring grooves for damage.
10. Air check all fluid passages.

11. Notice: After cleaning the transmission components, allow to air dry. Do not use cloth or paper towels in order to dry any transmission components. Lint from the towels can cause component failure.

Important: Dirty solvent can deposit sediment that could damage the transmission.

Thoroughly clean the transmission case assembly, including case threads, with clean solvent.
12. Clean gasket sealing surfaces. Remove all residual sealant and/or gasket material.
13. Using the J36850, install 2 new case cover O-ring seals on the transmission case assembly.
