O-Rings, Seals, Gaskets

WARNING: This page is about a different variant/trim than selected.

Always replace sealing rings and gaskets.
After removing gaskets, always inspect the contact surface on the housing or shaft for burrs resulting from removal and for signs of damage.
Coat O-rings with a thin coat of ATF at outer circumference and at sealing lip before installing.
Coat sealing rings with ATF or Vaseline before inserting in order to avoid pinching of the rings during installation.
Never use other lubricants in surrounding area of the ATF. Otherwise danger of improper functioning of the hydraulic transmission control may occur.
The open side of each sealing ring faces the fluid to be sealed.
After installing, check the gear oil and ATF levels, and correct if necessary.
