just fill it up via the fill plug or under shifter until fluid starts to come out the open fill plug hole, and then its full. From what I've read, the results are 2.5-2.8 quarts of fluid needed. Since my car has been on jack stands for over a month in the back yard due to me exploding a bearing in the rear end, I went ahead and changed out the t5 tranny fluid for some penzoil syncromesh. Hope the oil change fixes the notchy 1-2 and 2-3 shifts.
