27. Push A/T assembly harness connector.
CAUTION:
Be careful not to damage connector.
28. Remove oil pan and oil pan gasket.
29. Check foreign materials in oil pan to help determine causes of
malfunction. If the A/T fluid is very dark, smells burned, or con-
tains foreign particles, the frictional material (clutches, band)
may need replacement. A tacky film that will not wipe clean indi-
cates varnish build up. Varnish can cause valves, servo, and
clutches to stick and can inhibit pump pressure.

If frictional material is detected, perform A/T fluid cooler
cleaning. Refer to AT-15, "
A/T Fluid Cooler Cleaning" .
30. Remove magnets from oil pan.

8. Make sure that brake band does not close turbine revolution
sensor hole.
9. Install control valve with TCM.
a. Install A/T fluid temperature sensor 2 to bracket.
b. Install A/T fluid temperature sensor 2 (with bracket) in control
valve with TCM. Tighten A/T fluid temperature sensor 2 mount-
ing bolt to the specified torque. Refer to AT-261, "
Components"
.
CAUTION:
Adjust bolt hole of bracket to bolt hole of control valve with
TCM.
c. Install O-ring to A/T assembly harness connector.
CAUTION:

Do not reuse O-ring.

Apply ATF to O-ring.
d. Install control valve with TCM in transmission case.
CAUTION:

Make sure that turbine revolution sensor securely installs
turbine revolution sensor hole.

Adjust A/T assembly harness connector of control valve
with TCM to terminal hole of transmission case.

Hang down revolution sensor harness toward outside so
as not to disturb installation of control valve with TCM.

17. Install oil pan to transmission case.
a. Install oil pan gasket to oil pan.
CAUTION:

Do not reuse oil pan gasket.

Install it in the direction to align hole positions.

Complete remove all moisture, oil and old gasket, etc. From the oil pan gasket mounting sur-
faces.
b. Install oil pan (with oil pan gasket) to transmission case.
CAUTION:

Install it so that drain plug comes to the position as
shown in the figure.

Be careful not to pinch harnesses.

Complete remove all moisture, oil and old gasket, etc.
From the oil pan mounting surfaces.
c. Tighten oil pan mounting bolts to the specified torque in numeri-
cal order shown in the figure after temporarily tightening them.
Refer to AT- 2 6 1 , "
Components" .
CAUTION:
Do not reuse oil pan mounting bolts.
18. Install drain plug to oil pan. Tighten drain plug to the specified
torque. Refer to AT-261, "
Components" .
CAUTION:
Do not reuse drain plug gasket.
19. Install torque converter.
a. Pour ATF into torque converter.

Approximately 2 liter (2-1/8 US qt, 1-3/4 Imp qt) of fluid is
required for a new torque converter.

When reusing old torque converter, add the same amount
of fluid as was drained.
b. Install torque converter while aligning notches of torque con-
verter with notches of oil pump.
CAUTION:
Install torque converter while rotating it.
