The Superior “Super Tough Plate” saves time and money by preventing costly No-Go’s and comebacks in the Late 2000-up 4R70W/4R75W transmissions by helping to eliminate plate cracking and cross leaks caused by constant pounding from the2-3 Accumulator Piston Spring Retainer on the stock separator plate. Made in the USA, the Superior “Super Tough Plate” is zinc coated, extra thick and is the perfect replacement for the stock valve body separator plate used in this popular Ford application.
