The pan holds additional ATF and is finned. I haven't had any single complaint. Just use some thread sealant on the drainplug, which is magnetic btw
Also the pan uses allen head screws, and the one behind the crossmember are difficult to get to. BUT it is doable. You also have a allenhead scree near the corner that's use to pry the pan loose if it doesn't fall down after all 4 other screws are removed.
Over all it's a nice aluminum pan and decently made. I used a custom pan like this on a 5.0 maverick back in the later 80s.
i also have their diff cover also.
