The 4R100's cooler bypass tube assembly is known to fail and route fluid around the transmission cooler, often just when you need cooling most.
BD's kit lets you remove that assembly. It comes with two aluminum shunts and sealing washers, and it is worth doing as preventive maintenance whenever you install a transmission, cooler or filter kit, or do general service.
