CLEANING

NOTE: Fine and extremely fine metallic particles have been known affect valve operation in this transmission. While these particles may be to small to see with the naked eye, they can cause flares, or momentary going into neutral, on shifts.

Clean and flush the valve housings, valves, plugs, springs, and separator plates thoroughly with a standard parts cleaning solution only. Do not use gasoline, kerosene, or any type of caustic solution.

Do not immerse any of the electrical components in cleaning solution. Clean the electrical components by wiping them off with dry shop towels only.

Dry all except the electrical parts with compressed air. Make sure all passages are clean and free from obstructions. Do not use rags or shop towels to dry or wipe off valve body components. Lint from these materials can stick to valve body parts, interfere with valve operation, and clog filters and fluid passages.
