2-6 and Low-Reverse Piston Function Inspection

Callout	Component Name
1	Case Cover Assembly Tip:  The fluid seal rings should be in place and not damaged.
2	Apply shop air to the 2-6 clutch feed. Observe the 2-6 piston movement. NOTE: Regulate the air pressure to 40 psi maximum. High pressure could cause the piston to over travel and damage the piston seals. Tip:  Minimal piston movement and excessive air leaking could indicate damage to the 2-6 piston seals or improper assembly.
3	Apply shop air to the Low and Reverse clutch feed. Observe the Low and Reverse piston movement. NOTE: Regulate the air pressure to 40 psi maximum. High pressure could cause the piston to over travel and damage the piston seals. Tip:  Minimal piston movement and excessive air leaking could indicate damage to the Low and Reverse piston seals or improper assembly.
