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 can be removed with an external load of less than
39 N (4.0 kg, 8.8 lb), replace key interlock cable with new one.

Oil Pan

ECS00ELT

REMOVAL AND INSTALLATION
Removal

1.

Drain A/T fluid. Refer to 

AT-12, "A/T FLUID"

 .

2.

Remove oil pan and gasket.

3.

Check for foreign materials in oil pan to help determine cause of malfunction. If the A/T fluid is very dark,
has some burned smell, or contains foreign particles then friction 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.

CAUTION:

If friction material is detected, flush the transmission cooler after repair. Refer to 

AT-15, "A/T Fluid

Cooler Cleaning"

 .

4.

Remove magnets from oil pan.

Installation

1.

Install the oil pan magnets as shown.

2.

Install the oil pan and new oil pan gasket.

CAUTION:

●

Be sure the oil drain plug is located to the rear of the
transmission assembly.

●

Before installing oil pan bolts, remove any traces of old
sealant from the sealing surfaces and threaded holes.

●

Do not reuse old gasket, replace with a new one.

●

Always replace the oil pan bolts as they are self-sealing.

●

Partially install the oil pan bolts in a criss-cross pattern to
prevent dislocation of the gasket.

3.

Tighten oil pan bolts in numerical order as shown.

4.

Install drain plug with new gasket to oil pan and tighten to specification.

CAUTION:

Do not reuse drain plug gasket.

5.

Refill the A/T with fluid and check for fluid leakage. Refer to 

AT-12, "A/T FLUID"

 .
