Drive Range-2nd Gear

In this range, the forward clutch and intermediate band are applied. The transmission is in Drive range-second gear.

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 T.V. oil and the force of the 1-2 T.V. spring, thus allowing the valve to open and drive oil to enter the second (2nd) oil passage. This oil is called the 2nd oil and is directed to the intermediate servo and 1-2 accumulator piston.

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.
