New GM 6 Speed Auto . . . 6L80E!!

[6'9"Witha69]

Has anyone seen anything on this? I am behind in my reading and just saw a blurb in the May'05 PHR/CHP/CC mag (can't remember which one). It said it was going to be intruduced in the Caddy STS-V and maybe in some trucks with a TQ capacity of about 520 lb/ft.
This would be great, I could hold onto my 700r4 until I can get my hands on one.

Ain't she a beaut?

Here's more:
The aggressive torque curve (of the Notrstar SC STS-V acceleration capable of placing it firmly in the under-5-second-club for 0-to-60 time. The refined shift feel is enabled by careful electronic calibration of both the engine and transmission. During shifts, power is instantaneously lowered, then ramped back up carefully to make gear changes virtually unnoticeable.
The Northstar V-8 SC is mated to the all-new Hydra-Matic 6L80 six-speed automatic transmission – the first use of GM’s new six-speed automatic. The 6L80 – the only transmission offered on the STS-V – is one of the most technologically advanced automatic transmissions in the industry, using clutch-to-clutch operation and an advanced integrated 32-bit transmission controller to deliver smooth and precise shifts.
The 6L80 also incorporates a host of advanced driving enhancement features, including advanced Performance Algorithm Shifting (PAS) and Driver Shift Control (DSC). PAS lets the electronic transmission controller override the automatic gear selection during closed throttle high lateral acceleration maneuvers, rapidly downshifting with the release of the torque converter clutch for smooth powering up when the throttle is reopened. Driver Shift Control allows the driver to sequentially shift gears manually via the gearshift lever.
The STS-V has been tuned for performance on virtually every road condition and environment including GM’s all-new Milford Road Course facility and the Nordschleiffe (North Course) at Nürburgring.

How long does it normally take the aftermarket to get this stuff?

I would think that they wouldn’t even be close to affordable for quite a while as stand alone units. I'd like to be at the wrecking yard when they roll one in and score the tranny and electronics for peanuts. Hey a guy can fantasize right?

[Steve Chryssos]

Actually, it is a fully modular unit suitable for a variety of worldwide applications, so GM Hydramatic will be pumping them out like.....well I can't think of a good analogy....They're gonna make a lot of em.

Steve

I want one with your shrifter on it!

[Steve Chryssos]

Thanks. Yeah, me too. In fact, I will build the entire 65 Riviera project around it--Northstar SC powerplant and all.

Dang and I just scored a couple of 4L80E transmissions for my projects....now I am behind again....lol

I know things but I have been sworn to secrecy.. there is a post about what I am not allowed to say over at Digital Covette though..

[68LSS1]

Steve's secrets.

That's been a rumor for a while now. Glad to see it's finally been confirmed. 6 speed paddle shifted auto

WOOT. Very cool. I was thinking of doing a paddle shifted 6L80E in Fantom, instead of the 4L80. Hmmm, decisions, decisions.

[zbugger]

Wow..... Time to start saving again.

[protour_chevelle]

I don't know... Maybe its just me but I like a tranny that isn't busy all the time trying to find the right gear. 6 speed manual is a totally different story because when you mash it, its not searching for a gear where that manual, cripes.... rolling at 60km/h in 6th(while in driver) and you punch it or just speed up to pass someone your gonna go to 2nd or 3rd. To many changes for me.

Edit: During shifts, power is instantaneously lowered, then ramped back up carefully to make gear changes virtually unnoticeable. uhhhh, cool torque management. Weak sauce. I'd delete that in a hurry.

Ohwell, call me weird.

The SC CST-V with a T-56 is superb. With me driving and two others aboard it flat out hauled the bacon on the 1/4 mile.

The new trans? It's a joint Ford-GM project. Don't ask me how I know.

[CAMAROBOY69]

Now that would be awesome for my 67 Fastback project coming up within the next 5 years. Oh I mean my girlfriends 67 Fastback project.

[MoeBawlz]

isnt this new tranny suppose to be considerably larger than the 4L80E? which would mean probably some trans tunnel clearancing... but it would be one MEAN tranny to have...

I heard the joint Ford-GM rumor as well. But I'm getting way behind the curve here since my JL8 car still isn't done so I have no money to play around with any type of pro-touring car.

One could expect it to be larger. Otherwise the additional components must be made smaller (read: weaker) to fit. But you never know. This really is a whole new generation of transmission.
