Outline
The TCM drives shift solenoids No.1, 2, 3, 4, the pressure control solenoid, and the on/off solenoid based on inputs signals from each switch and sensor, and performs direct electronic control of the clutch engagement pressure. As a result, precise hydraulic pressure control of the clutch engagement, not possible using a conventional accumulator, is achieved.
Construction
Operation
N to D, and N to R selected
When N to D, and N to R are selected, the TCM drives the pressure control solenoid and shift solenoids No. 1 and 3 for optimum clutch engagement pressure control.
Shifting
During shifting, the TCM drives shift solenoids No.1, 2, 3, and 4 to directly control the clutch engagement pressure for optimum clutch engagement pressure control.
During each gear shift, the engagement side clutch pressure and release side clutch pressure are controlled simultaneously. As a result, the torque capacities of both clutches can be controlled in connection to each other when switching clutches, engine over-speed during shifting and interlock among clutches is prevented, and smooth and responsive shifting is achieved.
Planetary Gear [Fw6 A EL, Fw6 Ax EL]
Purpose/Function
The planetary gear is a mechanism which shifts the drive force from the engine.
The planetary gear consists of multiple gears which rotate individually while
revolving. By controlling the individual rotation and revolving of the gears,
the transaxle performs gear shi ...
