On my stock 49 woodie, I used the stock 3 speed trans and a 49 overdrive trans, combined the good parts, purchased new gearsets, bearings, tailshaft bushing, seals, etc., to build one good transmission. Several thousand miles later, and all good. My stock 49 had broken teeth, big mess inside. Got a few parts from Van Pelt. They know their stuff. Rebuild what you have. Check that tailshaft bushing, they wear and can cause driveshaft vibration. Might want to check your driveshaft U joints for wear. I did not and had a U joint break on Highway 49 in the California Sierras.
