I have a '75 GMC motorhome that had the transmission fail badly so removed it. Bought a rebuild th400 that came from an '87 Chev truck not realizing it was 27 spline and my original is 32 spline. I didn't take the rebuilder's tape off until I removed old from motorhome.
So, is it possible to swap old 32 shaft to the rebuild th400 ?
