TO-20 transmission Fluid

What kind should I use and how much do I need to replace the current fluid?

I would buy a repair or operators manual, might be the best money you can spend, if it keeps you from making a maintenance mistake.

My old 1957, TO35 uses mineral oil 90 weight in the transmission, gearbox and transmission, 8 gals.

But that might not be what your tractor calls for.

Best to check it out!!!!!

Lots of discussion on this topic in previous posts. Do a search on transmission oil or transmission fluid and you'll find many opinions on what to use.

Originally used GL1 90 weight.
Napa 65-205 for 5 gallons.
Book says holds 6 gallon. I would put 5 gallons in and after a few hours check the level. Might not need the 6th gallon or or only part of it.
