Bonneville V6-3800 3.8L (1991)
Begin with the "Fluid Leak Diagnosis" ("Automatic Transaxle On-Vehicle Service Section of the 1991-93 Service Manual") which provides a detailed
procedure in locating and repairing vehicle leaks.
If it is determined the leak is from the helix converter seal, the following procedure must be performed:
*
Remove helix converter seal taking care not to damage case bore.
*
Clean case bore with parts cleaner and air dry.
*
Apply a bead of LOCTITE 272 (or equivalent) at outer edge of converter seal. (This will insure a uniform coat of LOCTITE 272 (or equivalent) as
helix seal is installed.)
*
Install helix converter seal.
*
Wait 30 minutes before exposing helix seal with LOCKTITE 272 (or equivalent) to DEXRON-IIE (ATF). A 24 hour cure time is required before
vehicle should be started.
