Fine-Tune Your GMC Truck: Adjust Transmission Shift Points with Ease
To optimize your GMC truck's performance and fuel efficiency, you can adjust the transmission shift points using the factory settings. Start by turning the key to the Run position without starting the engine and fully pressing the gas pedal three times within five seconds. Turn the key off, hold the brake pedal, and turn the key back to the Run position to access the Service Shift Points mode. Use the up arrow on the steering wheel to increase RPM for shifts, boosting power and acceleration, or the down arrow to decrease RPM, enhancing fuel economy. Make adjustments for each gear as needed, and turn the key off to save your settings. For expert help, contact TTS to optimize your truck's transmission performance.
