Re: 6L80-E (Runge_Kutta)
One has to question the "80" designation. The 4L65E in the C6 has been described as modified to 400 lb-ft specs. Heck yes I want the six speed but the torque rating seems too low. Also is this the dual shaft?

Re: 6L80-E (Runge_Kutta)
This is the now old press release of Powertrain Technologies' 6 speed hydramatic. It reads like apple pie, Chevrolet and motherhood. After all the success in finding C6 details before the announcement date it is another thing that we are ignorant of. Is it actually headed for the C6 and if so when?

Overview:
GM Powertrain introduced its first 6-speed automatic in the 2001 Buick Bengal concept car.

Re: 6L80-E (Runge_Kutta)
The question is, will it even fit in the C6?
Additionally, what is the 6l80-e rated for on input shaft speed?

Re: 6L80-E (Curtis A. Franz)
Curtis,
I don't ever recall anyone ever attaching a name to these
transmissions beyond X13R, X14R, X15R, and X16R. Motor
Trend said 6L60-E and Hib Halverson said 6L65-E. I suspect
that a 6L80-E will be in the C6 lineup for MY2006 - once
the transmission family finally enters production.

That certainly is my hope. I just got Car & Driver and the Buick article there says the engine is rated at 400 lb-ft. I think I read too much into that Autoweek bit...the tranny can be rated at much more than the engine and that would be good. GM just never seems to do that tho.

Re: 6L80-E (Runge_Kutta)
Not just rear wheel drive but rear mounted, as in transaxle. Remember that Vette used a truck trans that was designed to enable four wheel drive application as well as two wheel in order to get the proper transmission housing to be able to mount it in the rear.
Before it shows in the Vette, any new transmission will likely be designed for the same applications. Watch the truck or four wheel drive auto announcements for a "vette-able" transmission.

Re: 6L80-E (I Bin Therbefor)
This is all I can find in the way of hydramatic news. It says calendar year 2006 and that is not good. http://www.gm.com/automotive/gmpower...ews/press2.htm

Re: 6L80-E (Curtis A. Franz)
Well in spite of that GM announcement here is a press release spun off that says 2005 calendar yearand the clutch to clutch (dual shaft) design. Gads, lets hope this one is correct...
New RWD 6-speed Hydra-Matic Transmission
Building on its strong heritage of transmission innovation, GM will introduce an all-new rear-wheel-drive family of Hydra-Matic 6-speed automatic transmissions beginning in the 2005 calendar year. The new 6-speeds, featuring multiple variants for GM cars and trucks, will provide performance improvements of about 4 percent to 7 percent and fuel economy improvements of about 1 percent to 4 percent.
Optimizing the flexibility and responsiveness of advanced microprocessor integration, the new 6-speed transmissions will feature a number of benefits such as an enhanced performance algorithm shift, clutch-to-clutch shifting, automatic grade braking and Driver Shift Control tap-up/tap-down operation.

Re: 6L80-E (Curtis A. Franz)
I guess this explains why we are still using he 4spd auto. Also it appears to me GM made the MN6 std so they can charge extra for the new 5/6 spd auto when it arrives.

Re: 6L80-E (Gene K)
One reason not to buy a 2005 C6. The 4L60/65E is a very primitive auto which requires many mods to make it shift correctly and withstand higher HP. Too bad GM will still be using this tranny in '05. We can only hope the 2006 car will have the 6-speed A6 transmission.
