4T65E New Transmission Pan

Been following these guys for awhile. Previously they sold a 1" spacer with new longer transmission bolts with new gaskets. It allows another 3 quarts of transmission fluid, as it has been shown that when the transmission is in 4th the pan is dry of transmission fluid due to the higher gear, gauging a blowout of the 4th gear clutches. ZZP also had a idea to help with their aluminum pan with drain plug and metal fans. I have also seen the dorman one with a drain plug but leaked.
