Drive Range, Manual 2ND (From Drive, Manual 3RD)

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 D2 fluid passage. The transaxle reacts by shifting immediately into second gear range and is prevented from upshifting into either Third or Fourth gear.

MANUAL VALVE (404)
Is moved by the gear selector lever allowing line pressure to enter the D-2 passage.

# 8 BALL CHECK VALVE (372)
Located in the valve body (300), is fed D-2 fluid from the manual valve (404) and directs it to the 2-3 shift valve (357).

2-3 SHIFT VALVE (357)
When shifted by D-2 fluid, it allows D-2 to enter the manual 2-1 servo feed passage to stroke the manual 2/1 servo assembly (104-115) and allows 3rd fluid to exhaust.

MANUAL 2/1 SERVO ASSEMBLY (104-115)
Applies the 2/1 band (680) during manual second and manual first gear ranges.

# 4 BALL CHECK VALVE (372)
Located in the case cover (400), it directs 3rd clutch/lo-1st exhaust fluid into the 3rd clutch passage, releasing the third clutch.

2-3 SHIFT SOLENOID VALVE (315)
When energized, it allows line pressure to enter the "B" shift solenoid passage and sends it to the 4-3 manual downshift valve (360) and 3-2 manual downshift valve (356). However, this event does not have to occur in order to achieve a manual 3-2 downshift.

3-2 MANUAL DOWNSHIFT VALVE (356)
Is shifted by "B" shift solenoid fluid and prevents the 2-3 shift valve (357) from upshifting.

TRANSMISSION FLUID PRESSURE (TFP) MANUAL VALVE POSITION SWITCH
D2 oil is routed to the PSA. The TFP signals the PCM that the manual valve i6 in the Manual Second position.

PRESSURE CONTROL SOLENOID
The PCM increases the PCS duty cycle to increase the operating range of torque signal fluid pressure in Manual Second. This provides increased line pressure for the additional torque requirements during engine compression braking and increased engine load in Manual Second.

TORQUE CONVERTER CLUTCH
The PCM will release the TCC before downshifting into Manual Second. The TCC will not re-apply in Second gear under normal operating conditions.
