    B&M Conventional Trick Shift ATF Automatic Transmission Fluid

    Trick Shift ATF was originally developed by B&M for racing applications. It’s become so successful that it’s the most popular high performance fluid on the street also. A scientific blend of foam inhibitors, pressure agents and shift modifiers that will provide extended transmission life and drastically improved shift feel. Trick Shift is the easiest way to measurably improve the transmission performance of your vehicle.

    Trick Shift works with all automatic transmissions when a firmer shift is desired (not recommended for electronic controlled transmissions). It can be mixed with stock-type transmission fluids, however to attain maximum improvement you should use Trick Shift exclusively. Ideal for towing, light trucks and RV applications as well as racing.
