Drive Range - Third Gear (TCC Not Applied)

In this range, the forward and direct clutches are applied and the intermediate band is released. The transaxle is in drive range-third gear (direct drive).

As both vehicle speed and governor pressure increase, the force of governor oil acting on the 2-3 shift valve overcomes the force of the 2-3 TV spring and shift TV oil. This allows the 2-3 shift valve to open and RND oil enters the direct clutch passage. This oil is called direct clutch oil.

Direct clutch oil from the 2-3 shift valve is directed to the following:

1. Direct clutch exhaust check ball.

2. 3-2 control valve.

3. Direct clutch and reverse check ball.

4. Direct clutch accumulator check ball.

5. Accumulator check valve.

6. Intermediate servo.

7. 3rd Clutch Pressure Switch.

Direct clutch oil from the 2-3 shift valve flows past the direct clutch exhaust check ball, past the 3rd clutch pressure switch, to the direct clutch and reverse check ball, seating it in the reverse passage, and to the inner area of the direct clutch piston, applying the direct clutch. At the same time, direct clutch oil is directed past the direct clutch accumulator check ball into the direct clutch accumulator passage, to the direct clutch accumulator check valve, seating it, and to the release side of the intermediate servo. The pressure of the direct clutch accumulator oil combined with the servo cushion spring, moves the servo piston against 2nd oil and acts as an accumulator for a smooth intermediate band release and direct clutch apply.

Direct clutch oil also flows through the 3-2 control valve to the direct clutch accumulator passage.
