REMOVAL AND INSTALLATION
Removal
1. Drain A/T fluid. Refer to TM-181, "Changing the A/T Fluid (ATF)".
2. Remove oil pan clips (1).
3. Remove oil pan (2).
4. Remove oil pan gasket.  : Vehicle front
 : Oil pan bolts
 Drain plug (3)
5. Check foreign materials in oil pan to help determine c ause 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 varnis h build up. Varnish can cause valves, servo, and
clutches to stick and can inhibit pump pressure.
CAUTION:
If friction material is detected, flush th e transmission cooler after repair. Refer to TM-183, "A/T
Fluid Cooler Cleaning".
6. Remove magnets from oil pan.
Installation
1. Install the oil pan magnets as shown.
