Had both the 4.45 5 speed and now the F40 conversion. Hands down the F40 swap is the way to go. Love the extra gear 80mph and 3.5k is sweet. Great roll racing trans for 3rd 60mph 4rpm.

Not for the track i have no idea yet. Slapping on a 6262 here next week and finally giving it a go.

 

Must be nice.

Sent from my Samsung Galaxy S4 using CobaltSS

 

I have a feeling ill be breakin loose in third

 

If you make decent power of coursel

 

461whp at 21lbs

 

Turbo? ANd i was around the same hp level.

 

Yes sir 2.1 girdled block. Fully built with a s256et stg2 cams p&p head

 

Are all f40 transmissions the same? I know they came in the g6's and the sabbs, Are they all the same or is there over the other which you want?

 

High hp want 07-09 for the close ratio gears. Takes power well. Must be out of a saab 2.0t

 

Damn that sucks. I've been thinking about doing this and just found a 0 mile f40 out of a g6 for $400.

 

Yea the g6 trans is cheap I had found one for $300 but they d9nt bolt up 5he the ecotec

 

also why there only 400 bucks. No one wants them.

 

Yes sirr

 

Checked the fluid in the f40 I picked up. The little bit that was left in it from the scrap yard draining it after they removed it from9m the car. Its pretty clean no metal shavings or debris.

 

Same with mine, drained it yesterday, no metal, also pretty red. Going to drop in some redline when I get the axle back.

 

Very red! Must be that $12/L gear oil saab recommends lol

 

I am not sure what Saab recommends but I am using redline, that's what ZZP uses

 

What weight is it? The saab stuff is 75w-85. gl-4

 

Pretty much the same. 75 weight. Gl4

 

Has anyone put there twm in there new 6spd shifter assembly? Any modifying need to be done or does it drop on

 

Needs to be modified, zzp did Ryan D's

 

Damn it! Tim told me in person today it cant be done :/

 

The years keep going by, but we are getting closer to what I've been looking for.

 

What are you looking to bulid the trans for? Dragging? Road course?

 

Hopefully I'll be joining the club in the next couple months too. I've got the ZZP kit already sitting here, but I'm waiting on the built/cryoed trans to come in. The ZZP kit apparently includes a clutch pressure plate now too, so you basically get a full flywheel+clutch setup with the kit now. I opted for the dual mass flywheel this time, coming from a Fidanza lightweight one. I think the car will run better with it. From what I've read the F40s seem to stand up to more abuse and are less noisy with dual mass flywheels.

There are around 8+ different versions. Some are different bellhousings, most are different gearing combinations, and a few are even auto. The one that'll work is the 2.0T Saab, as mentioned. The 07+ 9-3 one is the one of choice due to its compatibility and gearing. The newer Buick one would probably work, but the disadvantage of the newer one is the gearing isn't as advantageous for performance usage. Upside is you can get one new though.

Yeah, I heard that Castrol Burmah 75w-85 stuff is the OEM stuff (GM# 88862472 I think it is), but Redline can be used too.

From what I've seen, sometimes the transmissions are bit moody to shift until they warm up. Sometime with light usage they don't warm up, so it's common for people with F40s to only fill the fluid half full, so that the fluid warms up with/for normal usage.
