Description
A racing transmission operates under extreme stress—high RPMs, rapid gear changes, and sustained heat demand a fluid that can handle the punishment lap after lap. Brinn Transmission Fluid RT-1 is engineered specifically for manual racing transmissions, reducing friction while maintaining viscosity stability so you get consistent shift quality and protection when it matters most. Running the correct fluid in your Brinn transmission directly impacts durability, shift feel, and how long your gearbox stays reliable between rebuilds.
