Manual Third - Third Gear

Manual Third - Third Gear (From Overdrive Range - Fourth Gear):

MANUAL THIRD - THIRD GEAR

A manual 4-3 downshift is accomplished by moving the gear selector lever to the Manual Third (3) position. In Manual Third the transaxle is hydraulically prevented from upshifting into Fourth gear under any conditions. Also, the coast clutch is applied in all manual ranges to provide engine compression braking when appropriate. The following information explains the additional changes during a Manual 4-3 downshift as compared to a forced 4-3 downshift. Refer to Overdrive Range: 4-3 Downshift for a complete description of a 4-3 downshift.

FOURTH GEAR HYDRAULICALLY PREVENTED Manual Valve: The manual valve moves into the Manual Third (3) position and line pressure enters the D321 fluid circuit. Also, the manual valve blocks line pressure from the PRND4 fluid circuit and PRND4 fluid exhausts past the manual valve.

3-4 Shift Valve: D321 fluid pressure assists spring force to keep the valve in the Third gear position under any conditions. This opens the 4th band fluid circuit to an orificed exhaust and the intermediate / 4th band releases, thereby preventing Fourth gear.

Note: The operating states for the shift solenoids follow the normally operation depending on vehicle driving conditions. Figure 47 shows the solenoids in the Third gear position.

Pressure Switch Assembly: PRND4 fluid exhausts from the Pressure Switch Assembly (PSA) and the PSA signals the PCM that the manual valve is in the Manual Third position.


COAST CLUTCH APPLIES

3-4 Shift Valve: D321 fluid is routed through the 3-4 shift valve and into the coast clutch fluid circuit.

Coast Clutch: Coast clutch fluid pressure applies the coast clutch. With the coast clutch applied, engine compression braking is available in Manual Third - Third Gear to slow the vehicle when the throttle is released.

MANUAL THIRD - SECOND and FIRST GEARS

The transmission operates the same in Manual Third as in Overdrive range with the exception of Fourth gear being prevented. The transaxle will upshift and downshift between First, Second, and Third gears as in Overdrive range. However, engine compression braking is not available in Manual Third - First and Second gears and the vehicle will coast when the throttle is released.
