DRIVE RANGE - MANUAL SECOND (from Drive Range - Manual Third)

When the gear selector lever is moved to the Manual Second (D2) gear range, the manual valve moves and allows line pressure to enter the D21 fluid passage. The transaxle reacts by shifting immediately into second gear range and is prevented from upshifting into either Third or Fourth gear.

4TH BAND APPLIES

Manual Valve: Line pressure at the valve enters the D21 fluid circuit which is then routed to the 2-3 shift valve.

Pressure Switch: PRND43 fluid at the PRND43 indicator switch exhausts to open its electrical circuit to the PCM. The open circuit is a signal to the PCM that Manual Second gear range was selected by the vehicle operator.

Solenoid "B": De-energizes to allow solenoid "B" fluid to exhaust through the solenoid. In the absence of solenoid "B" fluid pressure at the 2-3 shift valve, the valve moves into the downshifted position from spring force acting on the end of the valve.

2-3 Shift Valve: Held in the downshifted position by spring force, D21 fluid passes through the valve and orifice #10 where it enters the orificed D21Y circuit. Orificed D21Y fluid is then routed to the 3-4 shift valve. D21 fluid also passes through orifice #9 where it enters the coast clutch circuit and is routed to the 3-4 shift valve. Coast clutch fluid is then directed to the coast clutch piston and applies the clutch.

3-4 Shift Valve: Held in the downshifted position by spring force and D321 fluid, it allows orificed D21Y to enter the 4th band feed circuit. 4th band feed is then routed to the 1-2 shift valve.

1-2 Shift Valve: Held in the upshifted position by spring force, it allows 4th band feed fluid to enter the 4th band circuit.

3-4 Accumulator Assembly: 4th band fluid is routed to the 3-4 accumulator piston and actuates the piston during the apply of the fourth band assembly.

3RD CLUTCH RELEASES

2-3 Shift Valve: Held in the downshifted position by spring force, the valve prevents drive fluid from entering the 3rd clutch circuit. In the absence of hydraulic pressure in the 3rd clutch circuit, spring force moves the 3rd clutch exhaust valve.

3rd Clutch Exhaust Valve: Held in the downshifted position by spring force, it allows 3rd clutch fluid from the 3rd clutch piston to exhaust through the valve. Orificed 3rd clutch fluid from the valve is routed back through orifice #3 to checkball #11.

#11 Checkball (3rd Clutch/Orificed 3rd Cl.): Located in the case cover, it is unseated by orificed 3rd clutch fluid, allowing fluid to enter the 3rd clutch fluid circuit.

2-3 Accumulator: Orificed 3rd clutch fluid from the accumulator piston passes through orifice #31 and enters the 3rd clutch circuit. 3rd clutch fluid is then routed to the 2-3 shift valve and the converter clutch control solenoid where it exhausts.
