I have an lq9/4l65 that I am putting into a volvo wagon (about 3200 lbs).

I need to swap output shafts to convert 4wd to 2wd. While I have the trans opened up I will be installing a Transgo hd2 kit. I was also thinking of replacing the clutches with Red Eagle Friction & Kolene Steels and putting in "the beast" sun gear shell from bulkpart.com while I have the trans open.

This car will be beat on. I am not trying to spend all that much money on the trans but I will spend whats necessary. Is there anything else I should consider? The engine will only have a tune/intake/exhaust, but there is a possiblity of nitrous in the future.
