Drive Range, Manual 3RD (From Overdrive Manual 3RD)

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 input clutch is applied in Manual Third range to provide engine compression braking in 3rd gear. 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.

MANUAL VALVE
The manual valve moves into the Manual Third (3) position and line pressure enters the D3 fluid circuit.

2-3 SHIFT VALVE (357)
Allows D-3 fluid to enter the input clutch feed passage and directs it to the 3-4 shift valve (362).

3-4 SHIFT VALVE (362)
Is downshifted when D-3 fluid is fed to the valve. In this position input clutch feed fluid enters the input clutch passage. 4th Clutch oil is exhausted thru an orifice.

No. 3 BALL CHECK VALVE (372)
Located in the case cover (400), it is seated against the PRN passage allowing input clutch fluid to apply the input clutch.

1-2, 3-4 SHIFT SOLENOID VALVE (315)
When de-energized, it allows "A" shift solenoid fluid from the 3-4 shift valve (362) to exhaust through the solenoid. However, this event does not have to occur in order to achieve a manual 4-3 downshift.

TRANSMISSION FLUID PRESSURE (TFP) MANUAL VALVE POSITION SWITCH
D3 oil is routed to the TFP The TFP signals the PCM that the manual valve is in the Manual Third position.

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 gear and the vehicle will coast when the throttle is released.
