Transmission Fluid Replacement
Written By: zz2h33
Did a drop and fill the other day and snapped some
pics. Since the subject is brought up so much, thought I'd share:
Items needed for a complete pan drop and filter replacement
- 8 quarts of ATF (9 if doing a lower shift kit)
- Filter
- Pan gasket (optional - gasket is reusable, only replace if damaged)
- Large rubbermaid-type container used to catch fluid
1.Place the drain pan directly under the tranny pan
2. To keep everything clean, you want the fluid to drain out of only one side of
the pan, so loosen the passenger side bolts more then the drivers
side...allowing the pan to drop further on the pass. side.

3. Allow the fluid to drain until dripping stops, then begin to loosen and
remove all the bolts progressively, starting from the passenger side. More fluid
will drain as more bolts are loosened.
4. Once all the bolts are removed, drop the pan into the drain pan and remove
the filter. The filter is removed by pulling straight down, it is not secured by
anything. Wiggling back and forth will help it drop down and out of the o-ring.
DO NOT REMOVE THE O-RING! It's a pain to re-install! Allow remaining fluid in
the tranny to drain.
5. If doing a lower shift kit (1-2, 2-3 shifts), the accumulator can be removed
now. Refer to your shift kit instructions.
6. Clean the gasket face on the tranny, removing all road grit/sand.
7. Remove the tranny pan from the drain pan and clean. Be sure to clean and
remove any metal shavings from the magnet. Clean the lip, removing all road
grit/sand from the gasket face.
8. Install new filter, the filter pushes into the existing o-ring, similar to
how the old one pulled out.
9. If reusing the gasket, wipe the gasket clean, removing all road grit/sand and
set on tranny pan. Install the pan with the gasket using one bolt to hold
everything together.
10. Install and hand tighten all remaining bolts. Using a ratchet, tighten all
bolts to approx 10-15 ft/lbs. DO NOT OVERTIGHTEN!! they strip easily.
11. Take the car off the jack and on a level surface. Start by adding 7 quarts
of fluid. Start the car and let it idle until warm, check the fluid while the
engine is idling and in park. Add remaining fluid as necessary. My car used 8.5
with a lower shift kit, others have said they used 7.5 without doing a shift
kit.
Done and not a single drop of fluid on the garage floor!
