Looking at upgrading my trans next....2001 9-3 "S" (lol).
Definitely going with the Quaife LSD and already have a 6 puck custom clutch disk from GS.
Am considering going with the stronger gearset from Quaife (6 speed).

Here is my concern....finding somebody that actually knows what they are doing when installing this gearset. I've spoken to a couple of local Saab specialists that hesitate to rebuilding the trans with this kit, then convince themselves that they can do it. I actually want somebody that has done this.

I'm located in Southern NJ just outside of Philadelphia.

BTW, engine should be putting out between 325 to 350 HP when everything is finished and in place.

I'm not adverse to having the trans pulled and shipped somewhere but would rather have it done locally just so I could keep an eye on the process.

Send it to:
Taliaferro Imports, Inc.
GenuineSaab.com
525 North Prince Lane
Springfield, MO 65802
USA

This way, you will not do a mistake!

But first talk to Nick ;)

P.S. why spend up to 6.000 USD for the gearkit, LSD and install, when there are other options (less $$$...let`s say half)?

what are the other options?

Other than pulling the trans out of a Cobalt SS and swapping the guts with the trans cases, what are the "less costly" options?

Care to share?

You can't just swap the guts over from a cobalt "F35" box and dump it itn your 01 my 93 "S" "F25" box. Thats a No go. the saab Viggen "F35" box still wouldn't get you there. I've got piles of f25 f35 and f40-6s "Whatever they call the 6spd ss tranny" laying around. If the parts mixed and matched & Fit in the cases i would be driving a 6 speed lsd 1999 93. Its the kit or Serious Demity style Engineering with a diesel box and custom axles.

So I just read Nicks wiki on the cobalt box, So go get the Cobalt box, If he says the guts fit, Try it.

Thought Jak Stoll had successfully swapped out a Cobalt trans in his NG900....if I remember correctly (which I probably am not) he did have to modify the case to get the gear set to work properly. Of course this is when he was in his old shop...probably a year or two ago.

I sized up the F40 guts one day and decided there's no way. But now that you brought this up I'm interested. What are Cobalt Boxes selling for? And would this swap need Viggen axles & hubs to fit in a standerd car? Basicaly f35 size axles.

Okay I was digging around on TSN performance board and it looks like Jak was fooling around with this in August 2006. It sort of sounds Frankenstein what he had to do to get it to work, and I have no idea if it lasted. Viggen axles were needed, some seals from the original Cobalt case were also needed, on and on and on the fragmented explanation went because he was playing around with this for a while. I may try to contact him but he's not in his own shop anymore...believe he is in Washington state now or maybe Oregon.

I found a brand new Cobalt SS transmission with the LSD for $1200 on ebay, so it is much cheaper but I'm not sure the gears are as strong as the Quaife gearset (believe the Quaife gears are straight cut).

Harvey if you figure this out I'm not too far from Baltimore.

Well I think the cheapest way to go is just put a f25 quaife in your current box, no axle swap needed and call it done. 6 speeds are cool but the f40s keep killing 5th gear and they don't sell parts to fix so I'm not real happy with the stocker. The Quiafe gear set might be REALLY be noisey with strait cut gears and then add the price of a diff to boot and its all over. bummer but closer to reality.

If you really want 6 speeds on you 9-3og, there are only 2 options:

- Quaife gearkit (there is one developed by Maptun, with a semi-helical cut)http://maptun.com/shopProduct.php?pid=2945&hl=197&cg=688&car=93
But seems to me the 6th is slower than the stock Viggen 5th ;)
Pros: bullet-prof internal. You can eventually brake the housing, but to find an F25 housing is not THAT hard ;). Also, you retain the F25 stock gear shifter (actuating the gearbox with a bar), instead using the F40 shitty cable shifter (slower shifts, if you know what I mean...there are some improvements, but nothing compares to Nick T.` 9-3og short shifter!);
Cons: THE COST!!!, the slower 6th speed, the louder noise (but not like with a straight-cut);

- retrofit a 6 speed gearbox F40 from a 9-3SS TiD 2.2 MY2003 (like I did). Check "my project" thread
http://www.saablink.net/forum/showthread.php?t=42630&page=9
post #171 & on

...it`s doable even in a home garage-well furbished with the tools (welding being crucial, for mountings fabrication).

Pros: less costly than the Quaife gearkit,
Cons: a lot of work, shitty gears shifter linkage (cables, which result in slow and unsure shifts), small mods to the car (some cutting even), custom parts and all kind of complications in such a project. But if you are not in a hurry (we call this WINTER PROJECTS), in 2 weeks everything can be ready, including engine rebuild, head mild porting, Quaife LSD installed, s.o.

You will need some parts (even a custom driveshaft axle), but in the end, I think you will get cheaper and with a nice DIY project ;)
If you need more info, just ask!

Harvey,

How many F40 failures have you had? I have not seen a single one, lots of 5- speed auto failures, but no manuals yet. The salvage yards down here can't give them away.

We have 3 coming next week and I can get them for a pretty good deal and will be installing them for a few people. Contact me if you are interested in getting one,

Answer, 3 bad 5th gears in the f40 since its introduction. Lots of clutches. Strangly No bad 5 speed"manuel" sport sedans, Just the 6 speeds. The manuel transmissions are probably one of the Most reliable parts on a SS now that I think about it.

Excuse my ignorance, but is so great about this 6 speed? I know 6 speeds are cool and all, but when I had a car with one I never used it. Or does this tranny have taller first and second gears, and is it stronger?

The gearing is what is awesome, try driving a car with a 4.45 and you will know what all the hype is about! You get much better acceleration, less stress on the box, its also stronger and better designed with new bearings and a end cap that has bearings for the shafts to run in and keep them aligned.

The largest part is a much longer usalbe first gear, 45-50mph and then second gear right behind it, no lag there at all, instant spool of the turbo and makes for a rocket ship of a ride. Then you get the same close gearing for 3rd, 4th and 5th and then 6th lets you have all that and cruise at 2600rpm at 85mph on the highway :)

So, with my race car, I will fall back to 5k when I shift to second gear and that will be the sweet-spot of my large holset turbo, instant spool and a much faster car. The gears are much thicker and stronger, you get a pinion shaft, ring gear, all gears and special bearings in the kit.

yep, 6th for cruising is great!
With my F40, in the 6th, at 2.400 RPM I cruise at 85MPH and at 4.000 RPM I have 150MPH!
Being limited at 7.200 RPM, I can go some 2.000 RPM more on the safe side...that`s a max speed of some 220MPH !!!
warooommm...but where???
