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 flowsthrough the manual valve and becomes line pressure (31. lt then flows through the 1-2 shift valve to the servo varvevia 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 speedin [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 outputs1st signal (A: OFF, B: ON), and the 1-2 shift valve is moved to the right side. The line pressure {3) is intercepted bvthe 1-2 shift valve; consequently, power is not transmitted as the 4th clutch and servo valve are not oDerareo.

Description
Lock-up System
Lock-up Clutch
1. Operation (clutch on)
With the lock-up clutch on, the oil in the chamber between the torque convener cover and lock-up piston is discharged,and the converter oil exerts pressure through the piston against the converter cover. As a result, the converter turbineis locked on the converter cover firmly. The etfect is to bypass the converter, thereby placing the car in direct drive.

2. Operation (clutch off)
With the lock-up clutch off, the oil tlows in the reverse of CLUTCH ON. As a result, the lock-up piston is moved away
from the converter cover; that is, the torque converter lock-up is released.

Disassembly/Reassembly
1, Using a hydraulic press, press out the countershatt
while supponing 4th gear.
NOTE: Place an attachment between the press and
the countershatt to prevent damage to the shaft.
CAUTION: Do not allow the countershaft to lall and
hit the ground.
2.Assemble the parts on the countershaft as shown
oetow.
NOTE:
a Lubricate all parts with ATF during assembling.
a Before installing the O-rings, wrap the shalt
splines with tape to prevent damaging the
O-rings.
