The Stovebolt Site Forums The Shop Area Engine Shop Manual overdrive tranny

I just bought a 5 speed borg warner overdrive manual transmission for my 63 chevy pickup which already has a 230 six & 3 on the tree trans. The old 3 speed trans. has a 10 spline input shaft; the new one (out of an '85 s-10 pickup)has a 14 spline one. The newer trans. will bolt right up to my bellhousing, I only have to replace my clutch to make it work. Has anyone ever done this swap before? Can I use the clutch disc and throw-out-bearing for the s-10 trans. along with my pressure plate for my 3 speed trans. I already have?

I've never done this on a 230 but I think you want to use your stock 63 bearing and presure plate with the s-10 disc. You just need to match sizes and spline on your disc, think the s-10 is around or a little less than 10", might me metric. I would also check to make sure you have enough splines on the input shaft for the disc to disengage from the flywheel. Carefull measuring or better yet a fit check withough the presure plate installed. One the 235 you have to cut back the front bearing retainer and trim the input shaft pilot, but don't know if this is the case on a 230.
