Pretty sure my 92 Chev 3/4 ton 4x4; 454/5speed uses ATF in the transfer case. Chain and two gears. 90k miles and doing fine. Using Type F in primary on bike. Seems to be doing well.

So, does anybody know if ATF in the primary affects the stator windings over time?

Yup, that's what makes me wonder if Minton knows what he's talking about.

BlackBart it should have no effect on stator windings as their are many elec connections and solinoids in a automatic transmission.

My 77 GMC 4x4 uses 10/40 in the transfer case, NP 203 it has chains, what they say is don't go lighter cause it's not optimum for the chains and don't go much heavier and don't use gear oil cause it(the lubricant) won't be thrown around the gearcase and it needs to be, like a primary.

Chevy and Ford have been running ATF in their MANUAL transmissions now for over a decade. If it holds up to them, it will do fine for a MC.

Some say the clutch feels better, and the "clunk" goes away. I don't know, I haven't tried it yet.

For me....it's cheaper, you can get it just about anywhere and I like the feel of the clutch. Most of the clutch manufacturers recommend using ATF to soak the friction discs in before installation.
