Not worth it, imo. There's a regular (dorman?) one with a plug. O'rielly even carries it, I think.
If you really want to step up the pan, a few members discussed this one. No one has feedback on it ..yet. http://www.grandprixforums.net/threa...from-cartuning
I like the cartuning one, just note a couple things. There's added capacity, but that takes up space. This pan will sit lower, not so good for lowered cars.
The added fluid advantage would best be used with a cooler, adding a further step and expense.
I was going to do all that when I did the Trans-go. Moved, so that took care of that. Maybe when it needs rebuilding.
