SmartLock® Trans Brake

Banks' electronic braking device automatically activates when conditions call for braking. SmartLock locks the torque converter and simultaneously raises transmission-line pressure, to smoothly reduce vehicle speed. Besides saving wear-and-tear on your service brakes, SmartLock prolongs automatic transmission durability by increasing its holding capacity, eliminating excessive clutch slippage, and cooling transmission-fluid temperatures.
