Please discard Corporate Bulletin Number 08-04-21-002 (07 - Transmission/Transaxle). Condition Some customers may comment on a red fluid leak from the transmission or transfer case area. Technicians may find that the fluid is leaking from the transfer case/PTU weep hole farthest from the transmission, near the passenger side. Cause The front wheel drive intermediate (inner) shaft seal may be leaking. Due to low ambient temperatures with various runout conditions between the intermediate drive shaft and the input shaft, the seal material may not properly seal automatic transmission fluid (ATF). Correction Replace the front wheel drive intermediate (inner) shaft seal with a new designed seal. Important Selecting the correct replacement seal is critical due to a 2008 mid-model design update. Use the information below to determine which seal to use. For additional information, refer to New Product Information in the Getrag 760/790 Transfer Case category in SI. For Acadia, Enclave, OUTLOOK and Traverse - For vehicles built prior to VIN Breakpoint 8J217964, use first design seal, P/N 19180998 (Green). - For vehicles built on or after VIN Breakpoint 8J217964, use second design seal, P/N 19206322 (Green). For Equinox, Terrain, Torrent and VUE - For vehicles built prior to VIN Breakpoint 86075818, use first design seal, P/N 19180998 (Green). - For vehicles built on or after VIN Breakpoint 86075818, use second design seal, P/N 19206322 (Green). For Suzuki XL-7 - For vehicles built prior to VIN Breakpoint 86115983, use first design seal, P/N 19180998 (Green). - For vehicles built on or after VIN Breakpoint 86115983, use second design seal, P/N 19206322 (Green). Notice Second design seals are not compatible with first design transfer cases . Installing a second design seal in a first design transfer case will create a transmission fluid leak due to interference with the input shaft. Seal Installation Installing the replacement seal to the proper depth is critical. Use the DT-48078 - Inner Drive Shaft Seal installer with a J 8092 - Driver Handle to install the seal 2.8 mm (0.11 in) (a) from the end of the input shaft. Refer to the Front Drive Axle Inner Shaft Seal Replacement procedure in SI. Parts Information Warranty Information For vehicles repaired under warranty, use the table above. Disclaimer
