Did you notice this > > > >> > Maximum validated gross vehicle weight: 6384 lb <<<<<< this thing can move a light tank... that is a M6 bolt pattern also..
I will be hunting one of these as we get into 07...

Nice post! Now all we need to know is when it will hit the streets, how much new, and when someone can afford one, lol, how much used.........OH!! Almost forgot, WHOZ first to install this baby?
------------------ Me, I sell engines, the cars are for free, I need something to crate the engines in.... Enzo Ferrari....
as it is an ''e'' I bet it needs a controler to shift so cost of the trans and install is only 1/2 the battle unless you grab the motor and CPU from the donor car too
too bad as that would be a sweet up grade for a auto v8 swap
------------------ Question wonder and be wierd are you kind?
Now, someone PLEASE find a slightly used LS4 setup and mate it to this... dudes that would be one FRIGGIN fast fiero. ANd efficient, too, I think the LS4 is all aluminum as well...
------------------ If you can't be good, be good at it.

GM's building some interesting hardware again. Cool! An automatic with that deep first gear - that's gonna be one terror of a tranny if it holds up well. It's almost enough to make me want to switch to an auto.

Anybody else notice this? I infer that this means the solenoids are actively modulated to vary the shift firmness depending upon engine load and RPM, vehicle weight, road speed, traction conditions, etc. ... similar to the Chrysler A604/41TE, for example. If so, this means that a rather sophisticated electronic transmission controller will be required ... even to implement a simple paddle shifter. I'd like to know more.

wet: 102 kg 2007 6T70 [~225 pounds] wet: 104 kg 2007 6T75 [~229 pounds]
Gear ratios: First 4.48 Second 2.87 Third: 1.84 Fourth: 1.41 Fifth 1 Sixth 0.74 Reverse: 2.88
Observations:
1) First gear is a stump puller (even much lower than reverse) ... perhaps useful for trucks or working SUVs, but of dubious value in a light, street driven car.
I noticed that as well...why the large gap between the 1-2 shift? And if they were going to build a six-shooter, why not have the first four gears closer together, and have the last two as a standard-geared overdrive in fifth, with a taller overdrive in sixth?

Because they wanted to build a 4 speed with a couple extra worthless gears..... duh
Ford actually did that with one of their existing truck transmissions. They just changed the PCM programming to activate an additional solenoid pattern. Voila! They can now advertise another forward gear ... at virtually zero additional cost to Ford. What they don't tell you is that the ratio of the "new" gear is only a few percent different than one of the other forward gears.
Ah, American marketing! And one wonders why Ford is in trouble ....

I can see GM upping the torque rating to 80 and putting it behind LS4's... GM does automatics well... if they'd only realize that there are lots of people out here who want STICKS!!!!!!

In a car like mine, the 4.48 ratio will be excellent to launch it. It will probably shift to 2nd by the 60' mark, but by then it will be spooled and ready to haul ass. I bet i can cut .2 off my 60' with this tranny.

The early 1-2 shift required by the 4.48 first gear may cost you more than you gain ... assuming that your tires can get all that torque to the ground. There's only one sure way to find out. (Grin!)

I thought that was the Allison 5 (now 6) speed that GM is using with Duramax diesels?
The Allison does this, but Ford did it back in ~1999 with the 5-spd auto in the Explorer. It was essentially the same hardware as the 4-spd auto, but they would use the overdrive clutch in conjunction with one of the lower gears (I think 1st) to get the bonus 5th ratio.

The GM people have had a 6 speed manual available in the G6 model for over a year now.

I noticed the 6-speed manual is in last years 3.9L G6 GTP w/ 240HP. For 2007, the G6 GTP gets the 3.6L DOHC with 252HP and the 6-speed automatic. The 6-speed manual isn't available with it. The 3.9L will still be available with the 6-speed manual in the G6 GT.
Odd that the manual isn't availalbe with the 3.6L, unless it's not rated for the power.

Is this the same tranny that GM and Ford worked together on?

And it's ONLY been in G6 GTP's. How many of those have you seen? Of the ones you've seen, how many had sticks? From a production standpoint, the 6 speed manual might as well not exist. GM pays that much attention to it.

I'm guessing they are doin one of two things only offering in the GTP version.
Putting it as an option to see how popular of a demand there is for one. Although I think this would be the wrong car to do so in. How many people are buying a G6 as a performance car? Most people probably buy it as a family car and if they get the GTP they probably also go with the auto since they probably wont be using the car for any fort of racing. A better car to do this with would have been the Cobalt SS or the Vue Redline.
or
They put it in the G6 GTP knowing that it wouldn't be a very popular choice. That way the people that DO get it will probably do some spirited driving. In return they will find any weak points that are in the transmission and not have as many out there to worry about. So it would save them money on warranty work. Then when they decide it's ready, it will probably be available in a lot of other vehicles.

I've seen 6 G6 GTP's. 3 of them were 6 speeds. (50%) lol!!
