Boost Bros Performance - 6.6L Duramax DIESELR HP Tuners Transmission Tuning (2017-2019)

DIESELR Transmission Tuning – 2017–2019 L5P Duramax

Take full control of your Allison transmission with DIESELR’s custom transmission tuning for 2017–2019 L5P Duramax trucks. Whether you’re daily driving, towing heavy, or pushing big power, this tuning is designed to deliver smoother shifts, improved clutch holding capacity, and increased overall reliability.

DIESELR’s transmission tuning recalibrates shift timing, line pressure, and torque management to eliminate the sloppy, delayed shifts found in the factory calibration. The result is crisp, consistent gear changes that not only feel better but help extend the life of your transmission under load.

Built with performance and drivability in mind, this tuning supports everything from stock trucks to fully built setups. Expect reduced clutch slip, better power transfer, and more confidence when towing or accelerating hard.

Features:

• Optimized shift timing for quicker, firmer gear changes
• Increased line pressure for improved clutch holding power
• Reduced torque converter slip
• Enhanced towing performance and drivability
• Designed for stock and modified trucks
• Helps prolong transmission life under increased power

Whether you’re chasing performance or reliability, DIESELR transmission tuning unlocks the full potential of your L5P’s Allison transmission.
