For 1990-2009 cars

Notice: The upper half of the valve body contains four steel check balls, also known as check valves. When you separate the valve body halves, do so with the upper half facing downward in order not to displace the four check balls. When you reassemble the valve body, confirm that you have positioned these check balls in their correct passages. Failure to observe this precaution may result in transaxle shift failure.

Notice: When disassembling the valve body halves, keep all valve springs, spring seats and plugs within their respective valves. Most valve springs are of different sizes and CANNOT be interchanged. Verify that all parts are clean and dry before assembly.

1. Remove 16 upper valve body bolts.
2. Disassemble the lower valve body from the upper valve body. Position the upper valve body on the bottom and the lower valve body on the top.
3. Remove the spacer plate and the gaskets.
