Drive Range-2nd Gear (Converter Clutch Released)

In this range, the converter clutch is released, the overdrive roller clutch is holding, the forward clutch is applied, the intermediate band is applied and the transmission is in Drive (D) range-second gear.

As both vehicle speed and governor pressure increase, the force of the governor oil acting on the 1-2 shift valve overcomes the pressure of M.T.V. up oil and the force of the 1-2 throttle valve spring. This permits the 1-2 shift valve to open and Drive 4 oil to enter the second (2nd) oil passage. This oil is, therefore, called 2nd oil. Second oil from the 1-2 shift valve is then directed to the intermediate servo, where it is used to apply the intermediate band, and to the 1-2 accumulator piston, where it moves the piston against accumulator pressure and the accumulator spring to maintain a controlled build-up of pressure on the intermediate servo during the 1-2 shift. This results in a smooth band apply.
