Earl uses Lucas Transmission Fix
Nothing to fix in my brand new truck, but it gets a dose of Stop Slip just like every other vehicle I own. The viscosity improves the efficiency of the torque converter, while the friction modifiers improve shifting even in brand new transmissions. I put a bottle in at every fluid change and the results are impressive.
