Sealing a sm420?

Has anyone figured out a good way to seal the top of a toploader tyranny?

I am trying to keep the fluid in there when I roll. I know there won't be much coming out, but when its sitting right next to your elbow in the buggy it could get annoying. Even having it totally covered would get oil all over the tyranny tunnel.

I was thinking about tiging a ring around the snout to give it a lip to clamp on and installing some sort of shock-boot-ish thing. But I haven't come up with an oil compatible boot.

Thanks
ROB

1970's Toyota landcruisers with a 4 speed had a great sealing booth that fit the top of the transmission tower.. you can order one from any toyota dealer...
One thing to keep in mind with the old transmissions is that they sometimes use the tower as the transmission breather.. if you seal it too tight you may need to add a breather hose

Use an inner tube from a bike tire. Hose clamp it on.

The stock seal on the G56 manual in 3rd gen Dodge's is garbage and tears but there was an ATV CV boot that was close enough to hose clamp on as a robust fix.

Might see if there's a CV boot replacement that matches the OD of your shifter and bose close enough to use.

I was thinking about that but I don't think it will like the oil and turn to mush. I have one around that I use to make larger rubber bands for holding limiting straps to shocks... I'll have to cut off a piece and try it out in a cup of oil.

The Toyota boot and CV boot are good ideas!

Thanks!
