Sounds like clutch chatter.

If so, I would not worry about it.

Mine used to do that also. Clutch chatter. I realized I was slipping the clutch more in reverse than first gear to control my speed while backing up. Now I just let it fully out like I do when going forward and all is OK. No more clutch chatter. It may work for you.

Have the same problem in our 1929.

Only when backing.

New clutch, pressure plate, pilot and throw out bearings.

Going forward it is fine.

I just live with it. Slip the clutch with very little gas and itís not an issue.

Enjoy.

I always assume the multiplate clutch is more likely to do this, but obviously it happens with single plate clutches too
