the STS-V version look like it might fit under the f-body... i'm sure the computer will not work with it... but maybe a later conversion could be made. the gears look strong any word on max power?

My understanding is its based off the TH400 family of transmissions, 4L80 ect.

Yeah I guess it does... 6 speed l80 the case in some of the pictures have c1 on them?

Looks to be interesting how this one does... this is the trans that Ford helped on? I read something about GM and Ford working on a 6 speed auto a year or so ago.

Also a few of the pictures looks like a direct fit in to the y-body the ones with the gear box bolted to it.

For awhile there was an auto 6 speed being developed, however it held less power than the 60E. I assume that project was abandoned for a tougher transmission.

Yes, the C6 is expected to get a version of the 6L80E sometime in 2006/2007.


As far as I know this is still happening.
There may also be a 4L65E upgrade/replacement known as the 4L70E.

quick question here, will this tranny be able to be bolted to say a big block in a chevelle?

okay, the race is on....

whos is gonna have the first 6 speed auto in one of these cars...let me know because i would love to donate my ride for r&r..

Maybe with some serious surgery LOL.

carbon04

hmm, i didn't think it would be that bad considering the 4L80 has the same bolt pattern as a th400 which bolts right up the big block and i think the chevelle tunnel would be big enough. I was just worried about how to hook up the electronics aspect of it. cause if this is viable that would be awsome

LS1LT1

Yes but does the TH400/4L80E bolt right up to the LS1/LS6/LS2 without modifying the bell?
Plus the all new 6L80E is supposedly a bit longer than any of the 4 speed OD units (and obviously the 3 speeds also) as well I think.

I did some reading on it and the programming for it is really sophisticated ... things like it holds gear and doesn't shift when the g's reach a certain point when cornering ... it sounds like it won't work right without the right PCM to run it.

It is my understanding that like the Allison 1000, the 6L80-E will use a separate Controller from the PCM.

carbon04

so i guess its a no

If it uses a separate controller, then I think you're in luck ... you'd need the tranny, the controller, and the harnesss - get juice to it and go, right?

I've seen adapters to put GM transmissions behind 4.6 fords and everything imaginable.
I don't see bolting it up to be a problem once someone designs and adapter (if it doesn't have the standard GM bolt pattern).
The biggest problem might be electronics which should also be no problem once someone developes a controller for it.

Will it be able to be transplanted into a C5?

Gm going to build to be bolted to gen 1,gen2, gen 3 motors and i will be putting one of these in my car !!

Also is going to be the same length as the 4l60e?

The 6L80E is available now in the 2006 Corvette with available paddle shifting.

....and in fact, the 4-speed auto is no longer available.
