The sealing rings on the mainshaft are synthetic resin with chamfered ends. Check the condition of the sealing rings and replace them only if they are worn, distorted, or damaged.

1. For a better fit, squeeze the sealing rings together slightly before installing them.

2. Apply ATF to the new sealing rings, then install them on the mainshaft.

3. After installing the sealing rings, verify the following:

- The rings are fully seated in the groove.
- The ring are not twisted.
- The chamfered ends of the ring are properly joined.
