(Section 04 - Driveline/Axle).
Condition
Some customer may comment on a fluid leak from the automatic transmission or transfer case area. Upon further diagnosis, the technician may find fluid
leaking between the transmission and transfer case or from the left hand transfer case weep hole closest to the transmission.
Correction
First, thoroughly clean the area and use fluid dye to isolate the leak. It is critical to understand the location of the leak and the fluid type (i.e. ATF or
transfer case gear lubricant). The transfer case left hand weep hole can leak both ATF and gear lubricant. If the leak is not coming from the transfer case
weep hole, DO NOT replace the transfer case left hand input shaft seal.
