when draining oil on my 1998 kx60 coolant came out and hardly any oil I did noyice that it looked like the seal on the shifter shaft may be bad that is why the lack of oil in the case, and I know that the motor may need a new top end,but is there anything else it could be.

no reason to pull the engine. even after removing the seal you cannot "see" the reason for leakage. a piston ring cannot cause coolant migration into the trans. i have some pics. give me a couple of minutes to post em. this is a very common issue with the kx60

exactly, the steel plates are rusting from the water/coolant. take the plates out and seperate them while you have the right side case off to do the pump seal. you do not have to replace them, but once the bike is together again you will need to "burn off the rust by slipping the clutch a little to wear the rust/glaze off of the plates after reassembly use ATF in the trans until the plates no longer stick.
