Oil PanECS00CKW
REMOVAL AND INSTALLATION
Removal
1. Drain A/T fluid, refer to MA-24, "Changing A/T Fluid" .
2. Remove oil pan and gasket.
3. Check 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, 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- 1 3 , "
A/T FLUID
COOLER CLEANING PROCEDURE" .
4. Remove magnets from oil pan.
Installation
1. Install the oil pan magnets as shown.
