No-Go Caddy

Some owners of 2007-2009 Cadillac SRX, 2007-2010 STS or 2008-2010 CTS equipped with all-wheel-drive (MX7) and 6L45 (MYA) or 6L50  (MYB) automatic transmission may comment that the vehicle has no forward or reverse gear at launch or has a grinding noise when forward or reverse gear is selected.

Upon further investigation, the technician may find that the transmission output shaft splines are stripped or damaged.

A revised transmission output shaft with an O-ring is now available. The transmission output shaft and the transfer case input shaft should also be replaced. Typically, there are no damaged parts in either the transmission or transfer case.

Important: After repairs, when installing the transfer case to the transmission, be sure to grease the transmission output shaft splines with high temperature wheel bearing grease, P/N 1051344 (Canadian P/N 993037).

Also, verify that the two locating (alignment) pins are pressed into the transfer case, as they may stick in the transmission during transfer case removal. If these pins are not in the proper location in the transfer case, proper alignment of the transfer case to the transmission is not maintained and damage may result.
