Mastering Downhill Control: Grade Braking vs. Engine Braking in Your GMC Truck
Grade Braking and Engine Braking are crucial for managing downhill speed in GMC trucks, each with distinct functions and benefits. Grade Braking uses transmission downshifting to increase engine RPM and provide additional braking force, making it ideal for towing heavy loads and driving on slippery roads. Engine Braking relies on the engine's resistance to slow the vehicle, enhancing fuel efficiency and conserving brake life but is less effective on steep grades. Combining both methods offers maximum stopping power and control, particularly on steep descents. For best practices, consult your owner's manual and seek expert advice from a Truck Transmission Specialist.
