Smoother Braking and a Stronger Transmission

When you’re hauling heavy loads or navigating steep grades with your 1998.5–2002 Dodge RAM 2500 or 3500 powered by a 5.9L Cummins, managing heat and stress on your transmission becomes critical. The Banks 55262 SmartLock Transmission Brake is designed to work in tandem with a Banks exhaust brake system to give you better control and added protection. When braking is needed, SmartLock steps in by locking the torque converter and increasing transmission line pressure. This combination reduces vehicle speed smoothly while also preventing the transmission from slipping or overheating under load. It’s a smarter, more controlled way to help slow your truck without relying solely on your service brakes.

Protect Your Investment Every Time You Brake

What makes SmartLock especially valuable is how it extends the life of your automatic transmission. By reducing clutch slippage and keeping transmission fluid cooler during braking, this system helps prevent long-term wear and breakdowns. Whether you're descending mountain passes or towing regularly, SmartLock adds a layer of protection that pays off over time. The kit includes the integrated SmartLock module, a wire loom, and all necessary mounting hardware, making installation straightforward for anyone upgrading an existing Banks braking system. If you want better downhill control, smoother braking, and added peace of mind, this is a smart addition to any serious tow rig.
