Water in Farmall Super A Transmission

I am in the process of completely rebuilding the Farmall Super A. Replacing nearly all bearings and seals. I just put the PTO assembly back on and put the Transmission cover and shifter back on. Which reminded me that I seem to have s constant problem of water getting in the transmission. On the gear shift there is a sheet metal cover that goes over the area where the shifter arm goes into the transmission. On top of that is a spring with a cup washer that is held in place by a pin through the shifter lever.
The cup washer appears to be upside down as it would appear to act as a funnel for water rather than shedding water.
Unfortunately the gear shift knob is JB Welded in place.
So suggestions for keeping water out of transmission?
Any other place it could be getting in.
Are there rubber boots that are available for this?
 
Cut the knob off and turn the washer over.Seal the gaps with clear silicone.How about using a rubber CV joint boot?
 
Doesn't sound like much of a restoration if you're not putting a new shift knob on it... Just sayin'.

They're not hard to replace. JB weld isn't permanent, will chip right off with a little bit of effort. Cut the old knob off, soak the new one in HOT water to soften it up, a little Dawn dish detergent on the tip of the lever, and the new knob slips right on slick as snot. Let everything dry overnight, and the install will be permanent.

This is one of those odd parts you can often get at Tractor Supply. Three of the six nearby TSC stores have it in stock:

saw knob off shifter ,turn cup piece right way , buy a new shifter knob. problem solved. DON'T LET IT SIT OUTSIDE. If it has to, at least cover it with something. My two cents worth. Pembroke
 
Truth is that the shift cover for a Super A was not designed to keep water out of the transmission/rear end. This was true of most of the old line tractors. When these tractors were used on a regular basis the heat of running would keep the water evaporated out. Now we just let them sit and they never get a good workout. I would suggest that you keep it out of the rain or at least provide a cover to keep water off the gear lever. There is nothing wrong with your gear stick. If you do a search of "Water in the transmission" you will find a good bit of additional information.
 
Write me I have an experimental rubber under cap that seems to be keeping out water over the past number of years
