REMOVAL AND INSTALLATION
Removal

1.

Drain A/T fluid. Refer to 

MA-24, "Changing the Automatic Transmission Fluid (ATF)"

 .

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.

●

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 to oil pan and tighten to specification.

CAUTION:

Do not reuse old drain plug gasket replace with a new one.

5.

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

sion Fluid (ATF)"

 .
