You are welcome! You might know this already, but you also need a fluid transfer pump for both the tranny and the diff, since there is not enough room up there to pour in from a bottle... I got mine from pepboys ($7.50, a "powerbuilt"), which is one of the cheapest and apparently one of the sturdiest and does the job quite adequately.
