Shift Kit

.... What's the best way to drain it, I'm installing a drain plug in the pan so it'll be easier later. I've got the correct location in the rear of the pan for it so I was thinking about punching the hole carefully in the pan and letting it drain that way.

You'll spill less tranny fluid that way. I would punch the hole at the center of your planned drain plug hole. There'll still be some fluid in the pan, but not brimfull!
