1969 140 drivetrain, OK, I replaced the clutch and rebuilt the gearbox. Replaced damaged syncro, new dog slides and springs, replaced layshaft. Before rebuilding the gearbox I could shift 1st, 3rd and 4th. It would grind going into second either from 1st to 2nd or down from 3rd to second. It had a damaged three gear syncro. Now, after the rebuild I can shift up in all gears, even at hot rod speeds, but cannot downshift from third to second or if in second cannot shift down to 1st. I can shift down when almost stopped. And usually if I push clutch in and give it a little gas and then shift into first. I have little free play and the clutch engages at about 3/4 way up. I have no more adjustment out on the clutch. I had the flywheel resurfaced. It is a Sachs clutch. I do not know now if it is still a gearbox or clutch problem. If I press the clutch in it disengages and revs engine at the 7/8 up pedal. I replaced the pilot bearing when I replaced the clutch. Do I need more adjustment to make up for the flywheel and new clutch? The box easily shifts through all gears when sitting.
