FYI I just checked Car-Parts.com. they list over 20 F40 Saab transmissions from cars with 2.8 l V6 engines.

Finally done building a shop so the real work in the LFX/F40 swap begins. I did a test fit of the flywheel/clutch/transmission to the engine. All seemed to go ok, but I have a question that I hope someone will have an opinion about. How many bell housing bolts are required for the transaxle to be sufficiently attached to the engine? I can easily get 8 bolts, but more than that will be a bit of a pain in the butt. The bolts along the bottom are the ones that are problematic..
Thanks,
Daryl

Hi all,
I need to pick the community brain. The LFX engine I am in the process of putting in my 88 has a motor mount/jack shaft bearing carrier that came on the 2013 Impala donor car. With the f40 manual tranny attached, the jackshaft is about 10mm lower than it was with the automatic from the impala. My question is if anyone knows if there is a mount that would fit my application? I realize it may be a long shot but if a mount exists, I would rather do that than build one.
Thanks
Daryl

Do you have a picture? You're using the Saab f40, correct? Saab flywheel and clutch? I ask because I'm very interested in swap and may follow in your footsteps... or 2.0T ecotec...

Engine man, some days I am just not paying attention. I forgot that the jackshaft I got was from a 4 cylinder. It came with a jackshaft support that was not also a motor mount. I don't know if the 2.8 turbo has what I need or not. Worth a check though.

What did the flywheel come out of?

These photos are of the Impala mount. Notice the mounting holes are about 1/2" off. The Saab unit does not incorporate the motor mount into the shaft bearing carrier. At least the one I got with the shaft doesn't, and it doesn't fit the engine block either, but that is probably because it is from a 4 cylinder Saab.
(First time posting pictures. Hope it works)

Daryl,

I'm into a very similar swap at the moment with a transverse LFX out of a caddy... I'm also using a saab 9-3 2.8 v6 F40 and have the saab half shaft setup as well.

If I read your post correctly, why are trying to make the Impala automatic half shaft/carrier work with your manual.... you could easily get pontiac G6 halfshaft/carrier combo from GM for ~$130 + shipping from several online GM parts dealers... or even scavenge a saab halfshaft/carrier if available....

Regarding the Saab F40, have you figured out a way to deal with the lack of a VSS? Not interested in a GPS VSS sender..... I'm looking at ways to adapt an ABS tone ring to the fiero DS CV axle to get the signal to the ECU. It should be possible to pull the bellhousing off the saab F40 and 'slap' it onto a 60 deg F40 to get an in-transaxle VSS... might have to go that way if a I can't get the abs tone ring to work. I think FieroGuro has cracked several F40 cases... might need to ask him on this...

Marc

Swapping the G6 F40 gear side of the transmission to the Saab bellhousing half would allow using the G6 VSS on the ring gear. The only potential issue is the G6 F40 case is missing 2 bolt holes from the later, more reinforced F40s. I don't know which style you have.

This the reinforced version with 2 extra holes:


This is the G6 F40 Version:


Another option is to pick up the Regal/Ecotec F40. It is a reinforced version and has a VSS ring added to the upper main shaft and a sensor location on the transmission case.



If you are going to start swapping the gear side cases, do that before you make your transmission mounts as the only common holes are the ones connecting the two transmission halves.

Also, many of the newer versions switched to a 2 bolt flange for the shifter mechanism. The G6 version has 3 holes.

It's Saab F40 from a 2008 9-3 2.8L Turbo... obviously I was after the global pattern bellhousing for mating to the high feature V6s... from initial inspection and look overs it's very very similar to the 60 deg F40, but will have to clean it up and get some pics up for us to compare..

Amazing what gets posted after I build a custom mount. 😝 as it turns out it may have been just as easy anyway. Other projects will be taking my spare time til after Dec 10th , o keep up the great work and if I ever figure out how to post photos, I'll show you what I've been up to. As it is now, I have been sharing them on the Arizona Fiero FB page.

Wild. Thanks for sharing. Is your G6 F40 the '06 or '07 version? The '06 cars have an MT2 gear ratios, while the '07's received the MU9 gear ratios. I don't know how many of these changes (if any others) were incorporated between the two transmissions.

All of my G6 F40s are the 2006 MT2 version. I am pretty sure everything on the cases is the same with the 2007 G6 version. Where I have seen most of the changes is across applications. The Opel case I have from the 3.09 final swap, has the reinforced case, deeper bell housing, and several other changes. When I look at pictures of the 2014+ F40 from the Regals, it has more in common with the Opel version than the G6 version.

It was from a GM Online parts lookup tool. I saved the diagrams for the entire transmission. Unfortunately, not every part has a part# associated with it.

The axles I went with are from a Cobalt 2.0l supercharged, with the Saab intermediate shaft.
