Lockup Cutoff Valve.

ab. Lockup Shift Valve (fig. 1-43).

The lockup

shift

valve

assembly includes a valve, stop, and calibrated spring.

Spring force pushes the valve down and prevents lockup pressure from

flowing through the valve. Applying G2 pressure to the bottom of the

valve moves it up against the stop, allowing lockup pressure through.

Directing modulation pressure to the valve allows the valve to move

up with less pressure from the bottom.
