AISIN (FYI)

The Aisin transmission is most often (but not always) found in the 2013-2021 HD Cummins Cab & Chassis pick-up truck models. It was an available option for standard pick-ups as well but, came with a price tag. Your Aisin equipped Cummins will run better than it ever has before with our Custom Engine Tuning, but at this time there is no transmission tuning available. Our engine tuning for your truck is specifically designed to maximize the full potential while maintaining the reliability of your truck. Others may run a 1-size-fits-all when it comes to 6.7L Cummins engine tuning, but if you have an Aisin transmission the difference is significant.

G56 (Manual Transmission)

The G56 Manual transmission is offered through to the 2018 model year. The factory clutch can handle a reasonable amount of added torque with an adult driver at the wheel. For these trucks, you get all four Custom Engine Tunes in individual files. Our Engine tuning for these trucks takes into account the difference in engine operation for manual transmission trucks.
