@ or @ Position
1. lst Spe€d
The flow of fluid throuth the torque convener circuit is the same as in S Oosition.The line pressure ( 1 ) becomes line pressure (4) and it becomes the 1 st clutch pressure (1O). The I st ctutch pressure
is applied to the lst clutch and l st accumulator; consequently, the vehicle will move as the engine power is transmitted.The line pressure (1) becomes the modulator pressure (6) by the modulator valve and travels to 1-2 and 3-4 shift valves.
The 1-2 shift valve is moved to the right side because the shilt control solenoid valve A is turned off and B is turned
on by the TCM. This valve stops 2nd clutch pressure and power is not transmitted to the 2nd clutcn.Line pressu.e {4) also tlows to the seryo valve and line pressure (1 } also flows to throttle valve B.

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.

Lll Position
The flow of fluid through the torque converter circuit is the same as in I position. The line pressure ( l ) becomes line
pressure (3) as it passes through the manual valve. Then line pressure (3) flows through the 1-2 shift valve to the servo
valve via the servo control valve. causing the shift fork shaft to be moved to the reverse position as in E position.
However. the hydraulic pressure is not supplied to the clutches. Power is not transmitted.

Transmission Control Module
Replacement
I The Transmission Control Module (TCMI is located be-
low the dashboard, behind the lelt side kick panel on
the driver's side.
CAUTION:
a All SRS electrical wiring hahesses are covered withyellow insulation.
a Betore disconnecting any pan ot the SRS wile har-
ness. connect the short connectors lsee page 23-7O).
a Replace the entir6 affected SRS harness ass€mbly if
it has an open circuit or damaged wiring.
1. Remove two clips securing the kick panel then
move it.
2. Disconnect the connectors and remove the TCM.

shift cable and adjust as required.
6. Tighten the locknut to 7 N.m (O.7 kgf.m, 5lbf.ft).
7. Install the lock pin on the adiuster. lf you feel the
lock pin binding as you reinstall it, the cable is still
out of adjustment and must be readjusted.
8. Move the selector to each gear and verify that the
automatic transaxle gear position indicator tollows
the automatic transaxle gear position switch.
9. Start the engine and check the shift lever in all gea.s.
lf any gea. does not work properly, refer to
troubleshooting on page 14-86 thru 89.
