When you install the Derale Series 9000 Plate-Fin Transmission Cooler # D13611 a little extra fluid will be needed. The last part of the installation instructions have you add fluid as needed and then drive the vehicle for a little while and recheck the fluid level. Not much additional fluid is needed unless much is spilled when you disconnect and reconnect the lines. Normally just a few ounces of fluid is needed.
