4. Shift Solenoid, Duty Solenoid and Valve
A: REMOVAL

1) Clean transmission exterior.
2) Drain ATF completely.
NOTE:
Tighten ATF drain plug after draining ATF.
Tightening torque:
25±2 N·m (2.5±0.2 kg-m, 18.1±1.4 ft-lb)

3) Remove oil pan.
NOTE:
Drain oil into a container.
4) Disconnect solenoid and sensor connectors.
Remove connectors from clip and disconnect connectors at 8 places.

(B) Low clutch timing solenoid (Gray)
(C) Line pressure duty solenoid (Red)
(D) Shift solenoid 2 (Yellow)
(E) Shift solenoid 1 (Green)
(F) 2-4 brake timing solenoid (Black)
(G) 2-4 brake duty solenoid (Red)
(H) ATF temperature sensor

5) Remove control valve body.
CAUTION:
When removing control valve body, be careful
not to interfere with transfer duty solenoid C
wiring.
NOTE:Be careful because oil flows from valve body.

3) Install valve body to transmission case.
(1) Temporarily tighten the valve body on the
transmission case.
CAUTION:
When installing control valve body, be careful
not to interfere with transfer duty solenoid wiring (brown).
NOTE:
Align manual valve connections.

torque.
Tightening torque:
8±1 N·m (0.8±0.1 kg-m, 5.8±0.7 ft-lb)
4) Connect harness connectors at 8 places.
Connect connectors of same color, and secure
connectors to valve body using clips.

7) Fill ATF up to the middle of the “COLD” side on
level gauge by using the gauge hole.
Recommended fluid:
Dexron IIE or Dexron III type automatic
transmission fluid
Fluid capacity:
9.3 — 9.6  (9.8 — 10.1 US qt, 8.2 — 8.4
Imp qt)
8) Run the vehicle until the ATF temperature rises
from 60 to 80°C (140 to 176°F) and check the ATF
level of the “HOT” side on level gauge.
