PROBLEM

The transmission modulating valve on the Forward clutch (no. 2) on many of the D5M and D6M Track Type Tractors can become unstable, causing harsh or chattering shifts. The instability is a result of a small piston volume, a small oil passage to the piston, and the valve design. A new valve, designed to be more stable, replaces the original valve and eliminates the instability.
