aight, that didnt make much sense, lol. my bad.
1st. drain all the fluid.
2nd. put bottom plug back in, take top plug out.
3rd. pour the fluid in anyway you find easiest(i.e. through the top of the tranny, the side directly in the whole, etc.)
4th. fill until you get fluid coming out of the top hole.
at that point, your done. thats all that you need in there. thats the reason for the hole. thats where you check the fluid level in a T-5 or T45 5 speed. put the plug back in and check for leaks. easy to do when you have a lift like i did, but be ready for a mess if your doin it on your back. lol.
i have also seen people(my brother in law) take the shifter off and push a hose down and put it in the hole i metioned above. its easier with 2 people, i did mine alone, but had the right tools to do it including the lift
