I have a stock 3spd tranny attached to my 216 now 53 3100. My truck also has the original rear end with the 4:11 gear. Would this (1947-54 Chevrolet Truck 4-speed) tranny bolt right up and be a good replacement for the 3spd? I am also thinking about having a 235 rebuilt and putting it in the truck to replace the 216. Its on Ebay right now #230383183319. Any info would help thanks.
