Reverse

Reverse:

REVERSE

DIRECT CLUTCH - APPLIED
REAR BAND - APPLIED

When the selector lever is moved to the Reverse position, the manual valve is repositioned to allow line pressure to enter the reverse circuit. Reverse oil then flows as shown.
1. Direct Clutch
2. 2-3 Shift Valve
3. Rear Servo Piston
4. Pressure Boost Valve

BASIC CONTROL

Reverse oil from the manual valve flows to the large area of the direct clutch piston, seats a "ball check", flows through a restricted passage and to the 2-3 shift valve. From the 2-3 shift valve, it enters the direct clutch passage and is directed to the small area of the direct clutch piston to apply direct clutch.

Reverse oil seats a ball check and flows to the rear servo through an "orifice cup plug" to ensure a softer shift and acts on the servo piston to apply the rear band. Reverse oil also acts on the pressure boost valve to boost line pressure.

Orificed cup plug is used on models rated 10,000 lbs. GVWR or under.

SUMMARY

The direct clutch and the rear band are applied. The transmission is in Reverse.
