Let's go with the "too many problems" theory! Although many people swear by the TT I do not like the complexity of it. The seal in the tube went and I put in one of those Okie seal/bushing parts. It went in well but one of the things they mention is to make certain there are no burrs on the splines or n the area which might cause the seal to tear and leak. I have been driving mine with the fix for a few miles but because of my paranoia I still crawl under the truck after each trip and check the trans fliud! Crazy or what! I have a Plan B in case it does fail and at present am rebuilding a 1957 three-speed transmission and a 1957 differential to replace the torque tube system. They are open drive.
