Replace

Transmission gaskets are made of rubber, cork, paper, synthetic materials, or plastic. Purchase a new gasket set for the transmission. Gaskets are not reusable. A gasket that was working fine previously could leak after reassembly.

Carefully follow the recommendations from the gasket manufacturer. Read through all the installation steps before beginning. Take note of any of the original equipment manufacturer's recommendations that could affect engine sealing.

• Before installing the oil pan, make sure its flange is flat.
• The gasket should be mounted with a few dabs of quick-drying contact adhesive. Gasket sealer is not normally used on pan gaskets except to hold a gasket in place. Rubber cement or gasket positioning sealer can be used if necessary.
• Carefully align the gasket before the adhesive dries.
• Wait until the adhesive is dry before installing the pan.
• Tighten the oil pan bolts to the recommended torque specification and sequence given in the service manual.
