Description
Hydraulic Flow (cont'd)
LEI Position
The flow ot fluid through the torque convener circuit is the same as in S position. The tluid ( 1 ) trom the oil pump flows
through the manual valve and becomes line pressure (31. lt then flows through the 1-2 shift valve to the servo varve
via the servo control valve, causing the shift tork shatt to be moved in the reverse direction.
Under this condition, the shift control solenoid valve A is turned on whereas the valve B is turned ofJ as in 3rd speed
in [Dil or lDs]l position. As a result, the 1-2 shift valve is also moved to the left. The ftuid (3'] will ftow through the ser-
vo valve and manual valve to the 4th clutch; power is transmitted through the 4th clutch.
Reverse Inhibitor Control
When the @ position is selected while the vehicle is moving forward at a speed over 6 mph ( 1O km/h). the TCM outputs
1st signal (A: OFF, B: ON), and the 1-2 shift valve is moved to the right side. The line pressure {3) is intercepted bv
the 1-2 shift valve; consequently, power is not transmitted as the 4th clutch and servo valve are not oDerareo.
