Transmission Tuning ($299) will help prolong the life of your 2011-2016 6.6L GM Duramax LML as well as give you some big performance boosts!
While the stock tune is perfect for the transmission line pressure, this is not so once you've tuned your rig and increased your max torque; the line pressure will be lower than what is needed. To prevent this we recommend TCM tuning to achieve maximum tuning benefits! This tuning features a more aggressive line psi slope which will model a torque curve 100% above stock. The line PSI is modified in such a way that the truck will still retain good mileage, yet hold high line psi--close to 300psi under full load.
