According to the info posted from the guy back in October last year there looks like theres 2 transaxle options, the current SS/SC MU3 (Saab F35) and an MWL (F40) option.

I wonder if the F40 is the same transaxle thats in the G6 GTP and if it swaps over to us SS/SC guys. Edit: The Pontiac F40 is listed as an MU9, so I have no idea what this new MWL tranny is.

 

Maybe the auto option being offered in the HHR?

 

ooo, new tranny. Just what I need.

 

That image has it listed as a manual option. I'm sure its a 6 speed, but what exact transaxle is beyond me.

 

Stop breaking **** and you wouldn't have this problem.

Beats me then.

 

**** I'll be needing something very soon that can handle tq. this fgp35 just isnt gonna last much longer

 

Yeah theres quite a few SS/SC's (or at least original SS/SC transmissions) that are in need of an upgraded tranny.

 

Isn't the F40 in the current 9-3?

Transmission gear ratio (1st) 3.77
Transmission gear ratio (2nd) 2.04
Transmission gear ratio (3rd) 1.37
Transmission gear ratio (4th) 1.05
Transmission gear ratio (5th) .85
Transmission gear ratio (6th) .71
Transmission gear ratio (reverse) 3.54

3.55 final drive ratio

 

Thats the one GM lists as the MU9. This one is being listed as an MWL. Not sure what the difference is.

 

Possible upgrades to handle increased power? GM uses the same tranny with the 2.8L Turbo'd V6 9-3 and that has 250hp. Probably will use the same tranny with the 300hp Viggen

 

I'm thinking either that or different gear ratios. Funny thing is they still list it as an F40 though. iono

 

would like to know the answer. if possible im going to bolt the f40 onto the lsj

 

With the turbo engine making peak power at what 5300-5400rpm. They don't need steep gears like they have for the LSJ. I think the standard 6spd ratio's with a 3.55 final drive would be perfect and provide excellent highway fuel economy.

 

I'm thinking the same, it would be a great upgrade for the SS/SC guys if this tranny has either an upgraded torque rating or better gear ratios.

 

does the lnf use the same block as the lsj? different internals of course but I wonder what the flywheel bolt-pattern is like?

 

Both should have the same crankshafts iirc. The block is slightly different, one being a Gen1 design and the LNF being the reinforced Gen2.

 

Hmm, to turbo this car or trade up for the LNF...

 

Because you aren't upside down enough on this one...

 

No orange for the LNF I bet. Although Sport Tint Red = FTW.

 

LOL I'd hate you forever. I LOVE Sport Red. I'll admit I even like it better than my beloved Arrival Blue.

 

Off topic, but what PCM is in the LNF cars? Same that is in the 2.4 SS's, just tuned for boost? 16 or 32 bit?

 

so are people thinking that we can bolt up the f40 to our lsj. would enjoy the 6 speed.

 

Yes, but does this trans have LSD? If no LSD is available, aftermarket as well... would be better off getting the Quaife 6spd conversion for our trans. For me, an LSD is a must.

 

What u need an LSD for?

 

very good ? im looking to pick up a tranny with lsd. i hope that the f40 has an lsd in it.
