Took a 80+ mile round trip yesterday in my 54 235 factory 3 speed. The car ran great. I went to drive it to work this morning and the car was a pain to put in 1st gear. Felt like I would have to grind the gear to get it in. I shut off the car, and looked under it to find about 1/2-3/4 quart of transmission lubricant on the floor. It is leaking from the flywheel/clutch cover plate from the hole in the bottom of it. I removed the plate but I can not see where the leak is exactly as I don't have a lift and tranny is still under car. I see in the shop manual a reference to loose clutch gear bearing retainer and was thinking maybe this is it? Is there anything I can tighten or adjust that my fix this leak, or does this require me to remove transmission from the car and rebuild the seals? Also the transmission makes no funny noises and has always been smooth up till when I parked it last night. Thanks guys for any possible help!
