Leaking transmission

In this case it appears the hole has worn. There is nothing to keep the cluster shaft from turning other than the friction in it's hole. Some rebuilder instructions look to have the shaft "tight" in the hole - so tight it won't drop of its own weight when you hold up the case. Tightening the hole IS probably the best initial solution. I would go on to a positive seal since that's the part that Henry obviously left out.

OK, but we are in the present day and the grooved shafts are available now so why grooves them now?

The cluster shaft and reverse idler shaft should not be turning there is a retainer at the back of the transmission.

Worthy query. It is well you brought it up. That is the point.
