The transmission is a sliding gear straight tooth spur gear type. It is fully on roller, or ball berings throughout. It can be driven into motion just by the air that is sandwiched between the clutch driven disk surfaces, and the PP/Flywheel. If the oil in the trans is 90 wt, (original) then changing to a multi wt gear oil that is thicker at higher temps (85-140) This oil will have a higher viscous drag, reducing the gear motion, but not eliminating it. The trans will still make clashing noises when shifting, it has no syncros, and is designed to handle this issue. The test is to start the engine with the trans in gear with the clutch down (test only). If the trans can be shifted through neutral to other gears easily and without any claching of gears (clutch still down) then it is very normal. If the trans spins up when going to another gear with the clutch down, it is draging, and it is still not right. Another method is to have a oldster that is familiar with operating Frmalls give it a drive. Modest gear clasking is par for the course, it is the nature of the era. JimN
