I have owned this 72 TR6 for 30 years or so. Within that time, I have done a few clutch jobs that went well. Recently I replaced a clutch with a new Roadster Factory "Magic Clutch" kit. While the transmission was out, I had a machine shop resurface and balance the flywheel. A new pilot bearing was inserted into the flywheel. The new clutch went together without problems. During the reinstall, my transmission refused to go in all the way. After multiple removals and alignments of the clutch, I was still unable to get the last inch into the engine. Finally I raised the engine about 1/4 inch and the input shaft finally slid into flywheel perfectly. Life was good. Unfortunately, I found the transmission was now locked up in neutral. I cannot get any movement out of neutral or rotation of the transmission output shaft. I hate to think I need to start all over. Does anyone have any suggestions or ideas where I can start or what may have caused this????
