Intermittent Range (Valves In Second Gear Position)

Intermediate Range - Valves In Second Gear Position:






INTERMEDIATE RANGE (Valves In Second Gear Position)

FORWARD CLUTCH - APPLIED
INTERMEDIATE CLUTCH - APPLIED
FRONT BAND - APPLIED
INTERMEDIATE ROLLER CLUTCH - HOLDING

A 3-2 downshift can be accomplished by moving the selector lever from Drive to Intermediate range. When the selector lever is in the Intermediate position, intermediate oil from the manual valve is directed as shown.
1. Pressure Boost Valve
2. 2-3 Shift Valve

Intermediate oil at the boost valve will increase line pressure to 150 psi. This increased intermediate oil pressure at the 2-3 shift valve will close the valve regardless of car speed.

For engine braking, the front band is applied by exhausting servo oil at the manual valve in Intermediate Range. This allows intermediate clutch oil, acting on the servo piston, to move the piston and apply the front band. Once the transmission is in Second Gear - Intermediate Range, it cannot upshift to Third Gear regardless of vehicle speed.

SUMMARY

The forward and intermediate clutches and front band are applied. The transmission is in Intermediate range - Second Gear.
