I saw some transmission mounts and shift cable brackets here:

They're for the Ecotech/tranny swap, but doesn't specify if it's the F23 transmission they're using.

I'm just looking at the size of the gears, and just giggling at how rediculously big they are compared to the 282, and Isuzu. Interesting theory on the layout.



Looks like first and second are the upper gears on the left, the lower one is a transfer gear, which rides on top of third, So 1st, 2nd, look pretty stout, and 3rd is way oversized. 4th and 5th appear normal, but those gears since the teeth are farther from the centerline of the shaft are inherently stronger given the same properties.

This is one hell of a transmission. My 232,000 mile Getrag is getting noisy, not to mention that its been behind a 3.4 DOHC for the last 16K. This might be the way to go.

So, Just mounts, cables, and clutch line eh?

And interfacing the hall effect VSS sensor. OBD2 computers use them, but the OBD 1 and OBD 1.5 VSS inputs are different.

l67 im running a carbed sbc, so the vss and all that is moot.

That's the F23 pictured.

Cables are the same just different mount brackets?
Plus wasn't there something to do with the slave cyl? or is that just the mount as well?

I might put my very expensive m2 / hm hybrid build on hold to try this set up out with my 3800 build.

ok l67 good point. how do you make the vss work with a 87 gt.

quote Originally posted by L67: That's the F23 pictured.

Yes, but that's a different bellhousing, and the mount pictured won't work on the V6 bell.

John was using isuzu cables if I remember correctly. I'm using getrag cables that are custom from California Push and Pull. You just need the right connectors on the ends of the cables, being a cable mount can be made to any specific dimension needed. You have to adapt the Fiero hydraulic clutch line to the F23's quick disconnect line. An example of that can be seen at the website Fierosound referenced.



Mera you'll want to talk to John about that. I watched him try to get a Dakota digital box to output the right signal one day back in '09 (it didn't work), and I know the last time I was in the car it didn't have a working speedometer - John is using a stand alone computer for a Ford. I've never had to engineer the correct signal converter because I get to use stock OB2 3800 PCM output.

The mounting provisions are different. As you can see in my photo below, it doesn't allow for that mount with 'our' bellhousing.



These are the things I would have let you guys find out the hard way before..

So Thelin's front mount doesn't work, but does the rear mount? Sigh... I am so sick of the 125C.

With some modifications, yes, his trunk side mount would end up working.

im pritty sure i speek for everyone in saying we really appriciate your imput jncomutt.

The vss works fine in a swapped car, my 3800sc speedo is working flawlessly in mine with the f23.

As far as shift cables I used 2 Getrag select cables and reversed the movement of the up down motion at the transmission to keep the shift pattern correct, very easy to do and doesnt require all that ridiculousness of rodger thelins method of correction, which in the end works also.

Did you use the computer output to drive the speedometer, or split the signal from the transmission to both the speedometer and the computer?

This community is LAWLZ sometimes, but IMNSHO it's pretty immature to delete all informative posts because a few apparent ignorant know-it-alls said that it wasn't possible to do what was already done.

I thought the F23 was a more known quantity around here, I suppose it just stood out more to me. I didn't know a lot about it that I know now because of this thread, though. Thanks to all who are sharing (and re-sharing) info.

I have two questions that I may have missed the answers to...
Are there any different 1-5 gearsets available in any of the other applications? (similar to how the Q4 282 has a few different ratios than the Fiero 282, etc.) It's good that there are a few FD options, at least.

Has anyone noted how high the Ecotec guys are shifting these? 7k, 7.5k, 8k?

That Saturn Vue version has a crappier fifth, in the general range of around 0.81, IIRC. It might have some use with the 3.63:1 final, like with a TDC 3.4 maybe.

If mounts and shift cable brackets were made I would also be very interested in purchasing...

------------------

allturbo, i have done some research here since i first read this thread and so far i like the 2009-2010 cobalt f23 option fy1 with 3.63 final ratio and .7 fifth gear. also on ebay there are helical lsd's for 300.00 for the f23. i have located a 2010 new cobalt f23 with a 2.2 bellhousing and am going to go buy it on monday for 750.00 here locally. then ill buy the helical lsd and put it all together and a decent gearset with stronger box and lsd for under 1100.00? not a bad option, so far. i am all ears for more info. since i am running a carbed sbc i guess i will have to figure out a speedometer. even if i have to resort to gps signal speedo...lol.

I used the computer output signal.

Edit to add: the f23 vss is around 24000 ppm in the Jbodies I dont have the laptop with the exact numbers with me but it would need some variety of converter if you didnt want to use the computer output (or didnt have the option)

Have any idea how much the trans weighs?

Damn, I just left the shop. If no one else pulls it from the specs, I can weigh my actual trans next time out.

quote Originally posted by L67: 75mm according to one of the spreadsheets I have saved on my HD.

Does this answer your weight question? No idea if its accurate, and with fluids, etc

Thanks that's not bad at all for weight. Looks like my n* is getting an f23 instead of the custom getrag.

for those of you that are interested... i offer kevlar clutches for the getrag 282 applications and now i will be buying a f23 and will also offer a kevlar discs for them as well likely late next week. ill keep you up to date if there is any interest. a stock pressure plate with a kevlar disc will hold @ 50% more than stock. a 1700lb pressure plate and kevlar disc will hold @ 100% more power. and a 2500lb pressure plate and a kevlar disc will hold @ 150% more power. and the ultimate 2700lb pressure plate and a kevlar copper combo puck clutch will hold up to @ 200% more power. i have built porsche and ferrari race cars for years, and have offered my clutches to them without failure. again i have a setup for the 282 and once i have a f23 i will build a setup for it as well. ps... porsches have used getrag transaxles for years and i have successfully built them so i have plenty of experiance in the transmission and clutch field. again only if others are interested.

EDIT; the clutch discs start out as new sachs german high quality hd discs, and my pressure plates are very high quality made here in the good ol USA.

Yes, but are *both* shaft centers 75mm?

Wow, You sure did! I clicked the reply button that was INSIDE your post, and this is the result!

I did that the other day. Somewhere you've got a tag inside another tag.

un****ed.

Really interested in this...Let's get a step by step build thread together...-Jason

agin i say if someone would donate ill do it. lol

If all of these claims are half as good as they sound, This information could literally not have come at a better time for me. My part list for a M2/HM 282 Getrag hybrid was almost ready to be purchased. Now, back to parting out tetanus Fiero lol.
