Duramax Tuner Pre-Tuned Replacement T87 15.5-16 GM 6.6L Duramax 6-Speed Allison 1000 Transmission

Unlock better performance from the Allison 1000 transmission in your 2015.5-2016 GM 6.6L LML Duramax with the Calibrated Power T87 Pre-Tuned TCM. This performance-calibrated Transmission Control Module is designed to optimize the electronic control of the Allison 1000, delivering quicker shifts, improved acceleration, better torque converter operation, and increased clutch holding capacity. The Allison 1000 relies heavily on its electronic controls to determine shift timing, torque converter lockup, and transmission pressure. When your LML Duramax is equipped with ECM tuning, larger tires, an upgraded turbocharger, or a built transmission, recalibrating the TCM can help the transmission better utilize the engine's available power. Performance-Tuned Allison 1000 Control Calibrated Power's custom TCM tuning reduces the time between shifts and electronically increases line pressure to improve clutch holding capacity. Optimized shift strategies help keep the engine within its preferred RPM range, while an improved torque converter lockup strategy helps put more of the engine's power to the ground. The T87 Pre-Tuned TCM can enhance the performance and drivability of both stock and modified Allison 1000 transmissions. Faster, more controlled shifts can make the truck feel more responsive while helping maximize the benefits of other performance upgrades. Choose the Right Transmission Tuning Strategy Smooth Shift Points are ideal for near-stock trucks, stock-size tires, stock turbochargers, daily drivers, and applications where a shift schedule similar to the factory calibration is preferred. This option is also a good choice for drivers who prioritize comfortable street manners and fuel economy. Aggressive/Elevated Shift Points are designed for trucks with upgraded turbochargers, 35-inch or larger tires, custom ECM tuning, or drivers who prefer higher RPM operation and longer gear holds. This strategy helps keep a modified LML Duramax within its power band to better utilize its available performance. Benefits of T87 TCM Tuning Pre-tuned T87 TCM for the Allison 1000 6-speed transmission Quicker transmission shifts Improved acceleration Improved torque converter lockup strategy Increased electronic line pressure for improved clutch holding capacity Helps prevent short-shifting during performance driving Helps keep the engine within its preferred RPM range and power band Improves drivability when used with ECM tuning Works with stock and built Allison transmissions Helps maximize the benefits of upgraded turbochargers and other performance modifications Ideal for Modified LML Duramax Trucks TCM tuning becomes especially important when modifications change the engine's power output or operating RPM. The T87 Pre-Tuned TCM is an excellent upgrade for LML Duramax trucks equipped with ECM tuning, box tuners, throttle boosters, larger 35-inch-plus tires, modified turbochargers, built transmissions, or other performance modifications. By coordinating transmission operation with the engine's power curve, TCM tuning can help prevent unwanted short-shifting and keep the engine in the RPM range where it can make the most power. It also helps ensure that aftermarket performance parts work together more effectively.
