well i dont know, you got me scared now. im gonna replace my clutch before the dune season, i might just try it out i got alot of john deere hygard. its a little thicker than ATF. but if you take a look at a tractors transmission. they got wet clutches and shit like that. the only problem i could see is maybe the seals are not the same material or something. i guess if it smokes some stuff ill let you give me the i told you so speech.
