Model Years Affected: 1998, 2003

Verified

The transmission output shaft seal may leak transmission fluid. On 2WD models, this leak can cause the transmission mount to become oil soaked, which will require replacement of the mount along with the leak repair. On 4WD models, if this seal leaks, the fluid will leak into the transfer case, causing it to become overfull.
