I overhauled my 3 speed out of my 49, it was easy. Had to replace the 1st/reverse sliding gear, that was easy, but an expensive part. Then I found it cheaper at Ida's Chevs. Brother, just my luck. Do you have the factory transmission overhaul booklet? That was a big help to me. Only place I had trouble was getting the center bearing out, it is held in with a circular clip. The booklet shows a special tool to open the clip. I improvised - trimmed down a tongue depressor, worked great!
