In Drive 3, transaxle drive is via the input shaft to clutches
B and E. The elements of this transaxle function are as fol-
lows:
S Clutches B and E are engaged to drive the rear sun
gear and rear planetary gear carrier clockwise.
S The clockwise rotation of the rear sun gear and rear
planetary gear carrier will cause the front planetary
gear to rotate in the same direction.Control
Clutch B Engaged
In Park and Neutral solenoid valves 1 and 2 are both ON.
Pressure control solenoids (EDS) 4 and 6 are also turned
ON.
When EDS 6 is ON, the fluid supplied from the reduction
valve flows to the safety valve, clutch valve B and holding
valve B. The oil that is supplied to the inlet port of the clutch
valve presses on the valve spool. Line pressure then flows
to the holding valve and check ball, engaging clutch B.
