this worked good,,, looked at others, but some of the fancy ones with tubes going through them,,, saw that welds broke and leaks were common.. This is just a basic pan,, solid, well made,, with a drain plug,, and if you want cooling,, get a tru cool tranny cooler, my temps have never gone above 180 towing 12000 pounds cross country,,, as far as this pan,,, very happy, can do drain and fills every 10,000. Get the gasket to,,, five star
