What causes tranny oil to foam?

It could be that you put in motor oil instead of gear oil in the transmission.
Gear oils usually have an additive in them that makes the oil "climb" the spinning gears instead of just frothing and whipping up in the case.

Well I'm glad you posted this thread. I now know to never use bel ray fluids.
Even with moisture in the oil,oil shouldn't foam. They add additives to prevent this issue. That junk Lucas oil stabilizer causes oil foaming as well.
Op. If it's foaming I suggest draining it and using red line shockproof. Foamed oil doesn't really protect anything and will accelerate wear.
Amsoil severe gear is also good as well as royal purple. Drain the bel ray. It's your bike,do what you like however oil foaming is a sure fire way to servicing the tranny early.
And the oil foams because of how the gears mesh. Air is squishes in with the oil in between the gears and the oil doesn't effectively do it's job. If it's foaming it's not doing it's job.

My indy used the Spectro HD platinum 6 speed oil when he installed my new gearset and case. 300 miles so far and I love it. He also put the Spectro HD primary oil in the primary and it seems great as well. I'll probably use Spectro from now on. Hope it works out for you!
