Cub transmission

What does it mean if the transmission is grinding when it is moving in gear but does not pop out of gear.

Likely bearing breakdown. Water in these transmissions (rain and/or condensation) takes its toll on bearing surfaces over decades of sitting around immersed in sludge. I am doing a rebuild now and after examining the bearing surfaces, I rejected all of the old bearings as not worth re-installing. Given the small amount of oil required in these trannies, I believe oil should be changed often, like every couple years at a minimum.

R U sure it's not coming from a final drive? Check the oil levels?

I went to the TSMOLY sight and purchased all the moly additives for the engine, tranny and final drives.
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.

Welcome to the forum from Arkansas. Maybe a little more information. A lot of cubs have some noise in the transmission. Some moaning and whining. So how much noise does it make. If it sounds like something is about to break you you need to first drain the fluid and flush and refill to proper level, and while you are at it pull the top and inspect to see if there is any visible problem.
