Quantities listed are approximate. Fill the transmission until lubricant is
level with bottom of the fill hole, with the vehicle in normal operating
position.

Water contamination is normally characterized as a
milky discoloration of the transmission fluid. Obvious
contamination of the transmission fluid indicates a
leak between the water and fluid areas of the trans-
mission cooler. Inspect and pressure-test the cooler
to confirm the leak; replace leaking transmission
coolers.
1. Drain the transmission when the fluid is warm. If
not already warm, run the engine until the trans-
mission reaches normal operating temperature:
160 to 200°F (71 to 93°C).
2. Park the vehicle on a level surface. Apply the
parking brakes and chock the rear tires.
3. Clean the area around the drain plug and the
transmission fluid pan. Place a drain pan under
the transmission and remove the drain plug. Ex-
amine the fluid as it drains.
4. Remove the 12 mounting bolts (six each) from
the two filter covers.
NOTE: A lot of fluid will drain when the filter
covers are removed.
