Red Line developed this 30304 Racing ATF transmission fluid for use in racing automatic transmissions which need the positive shift of a Type F automatic transmission fluid. This ATF contains no slipperiness additives, producing faster shifts and quicker lock-up, and can reduce elapsed time in drag racing. A higher viscosity compared to conventional Type-F transmission fluids provides higher torque converter efficiency at higher temperatures. The enhanced extreme-pressure protection provides five-times better film strength when compared to petroleum ATFs, reducing gear and clutch wear considerably. This product is designed to be used where Type-F fluids are recommended or for racing transmissions which need quicker shifts than provided with Dexron II fluids.
