The 6060 is a remote mount shifter like the mt-82, meaning it moves around under spirited driving which leads to missed shifts because of this excessive movement. The tremec magnum xl is a top mount shifter which = no movement for more precise shifts. The magnum takes alot from the 6060 and improves on it in every way making it a stronger better shifting unit then any other tremec tranny out there. You should drive a car with one, soon as you do you will want 1 no matter the cost!
