When Servicing transmissions with the new seal design, use the following precautions:
^
The outer diameter of the pump assembly and case bore must be clean and free of burrs or raised surfaces. Be aware of sharp edges that could
damage the seal during installation.
^
The seal should be clean and dry before installation. It does not require lubrication for installation.
^
The seal should be inspected prior to installation for obvious damage.
^
It is preferable to hand-start the seal positioning the seal evenly around the case bore before installing the torque converter housing.
^
The seal can be easily removed by prying it out, typical of a pressed-on seal.
^
The seal may be reused, however a thorough inspection must be performed. Inspect the seal for the following conditions:
^
Distortion of the metal carrier or separation from the rubber seal.
^
A cut, deformed, or damaged seal.
^
Refer to the appropriate unit repair information in SI for seal removal and installation procedures.
