If the production ones are being mated to a V6, they'll have the V6 pattern... no doubt about that... It's just that the picture is probably of an Ecotec unit.
www.gmpowertrain.com still doesn't have any specs on it. It's not like having a FWD 6 speed is a curse or anything, why do they refuse to admit that it is in use? NIH syndrome, maybe?

Is it just me, or does that bellhousing look a tad ... uh... shallow?
Norm
Yes,
It would be interesting to see what the clutch throwout mechanism is like. They may have been able to shorten it up with a hydraulic throwout bearing. You'd think for FWD applicatons GM was probably trying to get it as short as possible.

There is a new part number for the transmission but its not even in the GM computers yet. Its gonna be a while until these are released, probably in the winter time.

bumpity bump, any new info. I went to the dealer and asked about ordering the tranny, it can be ordered for $2200 US. I've got $1400 more to save and I guess I will be the lab rat. Has anyone seen one of these up close. I am worried about shifter linkage location, slave cylinder location, axle size and overall length. I wonder if these have a common spline with any other cars. It would make it easier to have a clutch made. I wonder if they have equal length axles like the kit WCF sells. If this thing is everything we are all hoping for, in a few years when these things are a little more plentiful, it could be the next big popular mod in the fiero community like the 3800sc has been. Maybe if it works out a company will start making adapter mounts and cables. I hope it is strong, I am tired of breaking drivetrain parts.

Some guy had connections to a GM person and talked him into releasing a F40 trans to convert a Grand Prix to FWD manual transmission.
If this transmission is indeed capable of being ordered at GM today, I will offer this....
I will install the G6 transmission to the Fiero for $1000. It must be attached to a 3800SC engine however. If you do not have a 3800sc car, I can work with you to have a turnkey install of that also. If you do not have a manual Fiero, I can work with you to have that also.
So to recap my $1000 offer... IF you own a 3800sc manual transmission Fiero today, and want to buy the G6 transmission from GM, I will install this for $1000 to your Fiero. I want to see what this is like, so $1000 is good for me in labor and parts needed for the project. I will build all the mounts, provide the shift cables, and concept whatever is needed. You just get the transmission and provide the 3800SC Fiero.
So lets say the transmission is $3000, and I charge $1000 for parts labor of the install, then you are out $4000 for a one of a kind deal that may be the cats meow..
I have said this before "GM will put this tranny on a V8 and offer it soon" The tranny may be a little stronger? It may have a different gear ratio? It is supposed to be offered in the Impala and Monte Carlo. The V8 will be the LS4 with DOD. GM was not shy about it at the LA Auto show this year. They BOLDY made this proclamation. But I guess plans can change?

I dont know about how soon, but I just want this transmission sold in huge numbers so the salvage yards will be getting them soon. Its like the 5.3 LS4, so far I know of 3 wrecked cars since its release, but the powertrains were not available for sale.I am not that interested in the LS4, but I will install one for sure in the future.
The 06 Monte Carlo lineup was to be Series III V6, and some V8 LS4's. The Monte does not get all the dress up items that Grand Prix is getting to keep GXP Grand Prix with the edge over Chevrolet.

Holy crap, if they come out with an LS4 6-speed combo, that solves any questions about what swap I want to do!!! I can get an LS1 to fit, but the LS4 6-speed as a combo would just be so much easier for packaging, etc. It should be hard to get that little sucker to 350HP or more. Heck, even the stock ~300 HP would be good to start.

kohburn lists the 282 final drive as 3.61, not 2.6. im no expert, but in know my 282 is closer to 4.11 than it is to 2.6 final. my first gear is almost useless.
the final drive isnt the OVERALL final drive..
the G6's final drive is 3.55:1, but the overall final drive in 6th gear is around 2.2:1

so does this mean i finally have a 6spd option for my 88. if this is the trans they are going to use on the v8 grand prix and stuff does that mean it will blot right up to a v8 in my fiero when i get one?

No. Not unless your V8 uses a stock FWD bellhousing. This transaxle will have the same bolt pattern as a stock Fiero transaxle. So if you need an adapter plate before, you'll need one with the new tranny.
But there are several V8s that bolt up, more or less. 4.9 and Northstar, and it looks like the LS4 will, but it's too early to see what other changes may be required.

The kicker is, that the transmission was given to 'em by the General himself.
I do agree with the cheapo camera tho.

Loydes offer to install one should get somebodys goat. I think that it will be a matter of time...and $$ for those of us that work for a living.

Here are the specs for the F40, max eng torque 245 lb/ft is nothing to brag about so far given the output of the engine swops that are being performed on the Fiero none the less if it is stronger than the Getrags of old it's an improvement. What's really attractive is the new 60 degree 3900 with cam in block variable valve timing that it's going to be bolted to, I'm not in as big a hurry to do my swop yet now that the options coming available are making a V8 unnessassary to obtain how output levels and turbocharging is much more attractive given that the new engines are incorporating piston cooling by way of oil jetting so that compression ratios above 10:1 have recommended fuel ratings of 87 octane. Here is the site with all the info you need on other options as well:
just kidding, I drove the g6 tonight and one of the sales people was sick and went home, so I got to drive it alone. Not sure if it had an lsd or not, it didn't have the normal pull to one side that the fwd cars do when you squeal the tires, Oh and i did. It squealed in second too, I don't know about third, I was in town and the cops frown on 60 in a 35.
in conculsion, this would make a great swap for our cars if it fits.

Running the numbers I see first gear is similar to my Getrag with the 3.94 final ratio gear. Somewhat low. OK when I had just the 2.8 but now that I have the Stage II turbo I wish I had the 3.61. The more horse power you have the taller you want the gears.
