So I am finished now with the timing chain guide job, but I still need to refill my trans since it lost a lot of fluid. I have a hand pump and an adapter to fit the pan. I went under there and took the center of the drain plug out expecting to see nothing come out, and a whole bunch came out. I just let it keep draining since the fluid looks pretty bad anyway, but I lost around 2qts. I guess not you have to leave the engine running before you can fill right? I knew you had to have it running and between 80 and 120 degrees to check the level properly.
