L
E Position
The flow of fluid through the torque convefter circuit is the same as in E position The line
pressure (1) changes to the
line pressure (3) and flows to the l-2 shift valve. The iine pressure
(3) changes to the line pressure (3') at the
'l-2 shift valve
and flows to the servo valve. The servo valve is moved to the right side
(Reverse range position) and uncovers the port to
allow line pressure {3") to the manual valve, The line pressure {3') from the 1-2 shift valve
flows through the servo valve to
the manual valve and changes the 4th clutch pressure (40). The 4th clutch
pressure (40) is applied to the 4th clutch, and
the 4th clutch is engaged,
Reverse Inhibitor Control
When the E position is selected while the vehicle is moving forward at spe€ds over 6 mph
(10 km/h)' the PCM outputs the
1st speed signal to shift control solenoid valves A and B; shift control solenoid valve A is turned
oFF, shift control solenoid
valve B is turned ON. The 1-2 shift valve is moved to the right side and covers the
port to stop line pressure (3') to the
servo valve. The line pressure (3' ) is not applied to the servo valve, and the 4th clutch
pressure (40) is not applied to the
4th clutch, as a result, power is not transmitted to the reverse direction'
When used.
'left" or "right" indicates direction on the hydraulic circuit'
