Additives:

1. Never put a seal conditioner in a transmission that is working fine or not leaking.
2. Read the label of any transmission additive prior to adding it to your transmission.
3. Never use a conditioner to any transmission that has more than 75,000 miles on it.

 
Pan Gasket: Use Molded Rubber (steel inner)

Always use the reusable rubber (steel inner) pan gasket.

 
Inspection: Valve Body
 

Note:

Do not remove separator plate unless valve bodies are full of junk.

Be careful not to allow separator plate to sag in front as this will allow check balls to fall out of their respective worm tracks.

Use one of the retaining plate bolts to hold the separator plate up.

Always replace gasket between valve bodies and separator plate.
1. Visually inspect all valve body bores for scoring and wear.
2. Test free movement of dry plungers/valves in bores.
3. There are kits available to repair common problems such as:

Accumulator Valve Body Modulator Sleeve and Plunger.
