KEY INTERLOCK CABLEPFP:34908
ComponentsNCS00090
CAUTION:

Install key interlock cable in such a way that it will not be damaged by sharp bends, twists or inter-
ference with adjacent parts.

After installing key interlock cable to control device, make sure that casing cap and bracket are
firmly secured in their positions. If casing cap be removed with an external load of less than 39.2 N
(4.0 kg, 8.8 lb), replace key interlock cable with new one.

: Bolt
5. Remove heated oxygen sensor 2 harness (B) from clips (1).
6. Remove bracket (2) from transmission assembly.
7. Disconnect A/T assembly harness connector.
8. Remove snap ring from A/T assembly harness connector.
9. Push A/T assembly harness connector.
CAUTION:
Be careful not to damage connector.
10. Remove clips (1), oil pan (2) and oil pan gasket.

: Vehicle front

: Oil pan mounting bolt

Drain bolt (3)
11. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
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- 1 4 , "
A/T Fluid Cooler Cleaning".
