I was trying to remove the transmission from the 1929 Chevrolet inline 6 the other day. I removed the 4 bolts and tried to back off the tranny. It did for about 1/16" and that's it. What could be holding it in? Maybe the clutch is frozen to it? Do I need to poor the WD and heat for a few years to get it out? Anyone have any ideas? Thanks for listen to me whine.
