TCI Max Shift Racing Transmission Fluid (RTF) has been tested and proven to run up to 30°F cooler, even during extreme-heat racing sessions and repeated usage. TCI RTF is uniquely formulated using a new oil-soluble molybdenum additive that greatly reduces internal friction and heat, yet it does not affect clutch and band lockup. It's made using base oils with extremely high viscosity indexes, and it contains a special de-foamer agent that reduces fluid foaming, even at 10, 000 rpm. In addition, TCI Max Shift RTF contains extreme pressure additives to help control gear fatigue and fracture, actually forming a fluid cushion to help prevent metal-to-metal contact.
