What is the 6speed auto called in technical terms. Just trying to see what to look for since I think my trans blew. Would mine be the 6L80? My 1st gear slips and then the car will shift up and down freequently.

Actually about 8900 mi on it. Never beat it but had fun driving it. Had code P0700 for the TCM and P2723. Dealer said no to warranty since the blower is on the car. Any suggestions?

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.

I had a problem with my tranny shifting up and down upon acceleration with my blower just recently. Had the shop disconnect and clean the terminals, and i dont have a problem anymore. Tranny actually reacts better. It used to hesitate to put itself in gear when going from reverse to drive and vice versa.

The "60" does not refer to the GVW rating, it's a relative strength rating GM uses based on input torque capacity (engine torque) with the higher number meaning more torque capacity. I have a 6L90 in my 1-ton truck with a GVW of 11,400 LBs...far off from 9000 LBs via your interpretation. The 6L80 in the C6 Corvette does not mean the C6 has an 8000 LB GVW, it's more like half that. Also, the "E" is frequently left off now since all of their transmissions are electronic although it's technically correct to list the "E". But hey, you got 3 out of 4 right and not many people know the alpha-numeric designation of GM transmissions actually mean something. Good job!
LOL
