Can I assume I have the 630V transmission?
It looks like there is a drain plug on the side of the transmission, can I drain it there? I realize I just have to be careful and not spill the ATF all over the place. The transfer pump I picked up looks like it has different sized rubber plugs I can stick in the drain hole after I pull the plug so hopefully I can catch most of it that way.
I plan on using 15W-40 motor oil, should I change it to motor oil, run it a little then change it again or won't it matter if it's mixed?
