FORWARD CLUTCH - APPLIED
INTERMEDIATE BAND - APPLIED

As both vehicle speed and governor pressure increase, the force of governor oil acting on the 1-2 shift valve overcomes the pressure of shift Throttle Valve (T.V.) oil and the force of the 1-2 T.V. spring. This allows the 1-2 valve to open and drive oil to enter the second (2nd) oil passage. This oil is called second (2nd) oil.

Second oil from the 1-2 shift valve is directed to the following:
1. Intermediate Servo
2. 1-2 Accumulator Piston

BASIC CONTROL
Second oil from the 1-2 shift valve is directed to the intermediate servo to apply the intermediate band. At the same time, 2nd oil moves the 1-2 accumulator piston against 1-2 accumulator pressure and the accumulator spring to maintain a controlled build-up of pressure on the intermediate servo during the 1-2 shift for a smooth band apply.

SUMMARY
The forward clutch and the intermediate band are applied; the transmission is in Drive (D) Range - Second Gear.
