Any Ford dealer with have the Ford compatible ATF, Vauxhall/Opal will have the GM version which is slightly better.

Polaris used Type F in the front wheel sprag drives in ATV's.
(US availability)


Ford transitioned from Type F to MERCON/DEXRON about 1977. Kinda hard to find in stock in the US.

I have used synthetic DEXRON (Mobil 1, and Amsoil) 35,000 miles in the Commando, Barnett plates.

No slippage.
Ever.

i got ya bud, going to see can i get it local, im going to replace the oring seal anyways so will drain all the 20?50 out of it
 
Any automotive supply store should carry ATF type F (not a brand). Very common.
Regarding possible damage from crankseal failure, immediate issue will be primary filling with engine oil while riding, to the point where it comes out the felt seal and all over back of bike, onto rear tire etc. If not noticed, you could have a crash.

Happened to my bike after starting with a wet sump condition. Blew the crankseal in to two pieces and had an oil soaked tire after 30 min ride.

Can't see much as they are not big enough to see detail, but the use of sealant and marks on the joint surfaces show you need a new seal and the surfaces need attention. High spots are much more likely to cause a leak than low spots, so dress the mating surfaces to remove any high spots, a flat file will remove the high spots and leave a flat surface as long as it always touches both sides to keep it level.

Correct way to use a file, note each file touches the cover in 2 places.

That oil container full of oil is that what came out of the primary case, if so way too much oil or did you do a oil change from your motor.
As I said should be no more than 7floz.
 
When you put a new sealing rubber in do not and I mean do not over tighten that centre bolt nut, over tightening it will warp the outer cover and you will get leaks, just tight enough for the seal to do its job, so many over tighten the nut thinking the tighter the better but it's not.

That bolt joint is designed to shoulder up. That is, when properly shimmed, the shoulder nut pulls the cover snug enough to compress the gasket, and then hits the shoulder.
A well engineered setup that is not sensitive to over torquing.
