Fig. 68: D Position: Driving In 5th Gear Hydraulic Flow
R Position: Shifting to R position from P or N position
When shifting to the R position, the PCM turns shift solenoid valves B and E ON, and A, C, and D OFF. Shift
solenoid valve B pressure (SB) is applied to the right side of the shift valve B, and the shift valve B is moved to
the left side. Shift solenoid valve E pressure (SE) is applied to the left side of shift valve E, and shift valve E is
moved to the right side. Line pressure (1) changes to (3) at the manual valve, and flows to the servo valve via
the shift valve E. The servo valve is moved to reverse range position. Movement of the shift valves B and E,
and servo valve creates 4th clutch line pressure between the 4th clutch and the A/T clutch pressure control
solenoid valve A. The 4th clutch pressure (40) is applied to the 4th clutch, and the 4th clutch is engaged gently.
NOTE:
When used, "left" or "right" indicates direction on the hydraulic circuit.
