I have a 3.52 manual transmission that came out of a 91-92 metro that I am going to install into an 87 mk1. I know it is a direct bolt up, but my old cv shafts are toast and need to be replaced.

Would I need to get shafts for a 87 or for the 90's model geo?..was thinking them all to be the same, but I see they are not.

That transmission will bolt up to Mk1 but that is as far as you will get . There is no provisions for Mk1 mounts on Mk2 tranny. Also you will need custom axles. I wish myself it was as easy as you thought :wink:

I figured their might be some headache with the mounts but have had to do similar before. Running a self made mount on my 86 tranny now as they dont offer ones for Automatics anymore. On the term custom shafts...are you referring to a set of std shafts that have to be cut/shortened and welded? From what I see so far, the splines on both the tranny and wheels are the same, figuring length is the issue.

Any info or expereince on this swap out appreciated.

Hmmmm...has no one ever attempted this other than, OK it bolts up but now we got problems and quit? Anyone out there ever take it any farther and prove there is no way reasonably possible to make it happen.

If so what did you find to be the obstacles? Did none of the mounts work? did maybe one of them work and others had to be improvised?
Mounts can be made i've done it rather easily and use it daily on my 86.

On the shafts, whats the issue? is it the joints, is it the shaft length.

mk1 perfect fit trannies are getting more scarce than hens teeth. If the one you have is a turbo model with the first gear problem, I have not heard of a soul that has been able to fix that. Or has posted a topic about it. Gotta look at options if your gonna keep a classic mk1 on the road.

You can make it work. Use your cross member from the mk1 and the mk1 mounts and just fabricate the part that bolts to the trans from there. If you put it in place with the engine mounts on the engine.I would think that axle length would be real close to factory. I do not know about axle splines though. If you have a axle rebuilder near your location they could fix you up with what you need. I started to do this on a 88 turbo sprint. But car was traded before I could finish.

Thanks for the input Hotrodray.....kinda what I figured might be the situation. Not beyond fabbing anything at all. Everything I am seeing so far before starting all of this leads me to beleive that the length on the shafts should be near the same. Luckily the tranny I have came with the joints stuck into it, just to protect anything from going into the open holes during shipping or whatever. With those on hand I can easily compare spline setup to the OEM for the mk1 setup. Yeah, Ive already checked into a few sources for custom shafts and the price isnt much more than a rebuilt set of std shafts. Just like a custom drive shaft on an old chevy or ford, all they have to know is spline specs and distance. My old mk1 shafts were toast anyway so new shafts of some sort were part of the project.
This project is an 87 turbo sprint with the 1st gear problem. I got the car a few years ago with plans of converting my 4dr automatic to a turbo5 speed. But the old thing ran so good coming home I never could make myself do it. Rust may eventually force me to do it anyway, but if the body is able to be saved will stick with the 2 dr. Would like to fix the oem tranny, but 3 years later still have not heard of anyone having luck doing so, and no parts at all to be found to fix the common 1st gear slipping situation.
