The tranny fluid would go in the trans/gearbox not the crank case. You dont add anything to the crank case it is lubed by your premix!!!!!!!!!!
I know some guys do it. I see no harm in it, it is a trans. I think you have to run type F tranny fluid.
I am thinking about switching over to it but unsure if you should change the clutch plates or not. Since the are soaked in regular oil alread.
One thing to remember that you are only running it in the trans of the Blaster. You run trans fluid in the trans of your car right not motor oil.
