ISSUE:
The transmission may have low fluid level and/or may have either a shift concern and/or an engagement concern. This may be caused by transmission fluid leaking from the transmission into the transfer case through the transfer case input seal.
ACTION:
Replace the transfer case input seal. The new seal should reduce the possibility of fluid leaking from the transmission into the transfer case.
