Actual TSP
This was posted in a thread of mine a few days ago. Does anyone actually know what the TSB is for this? It will make it much easier for the deale to cover my transmission repair if I am able to find it since they can't.
Thank you.
from GM. The document ID#1875647 covers 2007 GMC Yukon Denali, Cadillac Escalades & 2006 Corvettes with a 6L80 transmission. The related DTC's are P0777 or P2723. Your dealer should be able to easily confirm the codes. The conditions read as follows: "Some customers may comment on a condition of no movement, or slipping or binding in forward range. They may also comment on an illuminated MIL and Technicians may find DTC P0777 or P2723 may be found as a history code in the TCM. The Recommendation from GM is: "This may be the result of the 1-2-3-4 retaining ring (429) coming out of the groove in the 1-2-3-4 and 3-5-R clutch housing (427). When this retaining ring comes out of the groove a slipping 1-2-3-4 clutch can be the result. Changes to the 1-2-3-4 retaining ring (429) and the 1-2-3-4 and 3-5-R clutch housing (427) were implemented May 30, 2006 in the transmission assemblies to prevent this condition.
