There are 2 plugs on the fender side of the transmission, the bottom one is the drain and the top one is the fill/check plug.

- Unscrew both plugs(fill plug first) then let the oil drain out.
- Screw the bottom plug on and tighten
- Fill case from fill plug hole until oil comes out(almost like you're over filling it)
- Screw the top plug on and tighten after the oil stops dripping out and you're done.
