What are the tips for shifting gears in Dongfeng 14-speed transmission?
2 Answers
The shifting tips for Dongfeng 14-speed transmission are that you need to press the half-gear switch when converting between low and high gears, but you don't need to press the half-gear switch when converting between high and low gears, just follow the normal clutch-pedal shifting process. Taking Dongfeng Fengshen AX3 as an example, here is the specific introduction of Dongfeng Fengshen AX3: 1. Configuration: Dongfeng Fengshen AX3 comes standard with ACC cruise control, HHC hill start assist system, ESP electronic stability program and other safety configurations. 2. Power: Equipped with a 1.0T engine that adopts technologies such as turbocharging, direct fuel injection, and variable valve timing for intake and exhaust, with a maximum power of 92kW (125PS).
I've been driving heavy-duty trucks for over 30 years, and shifting the Dongfeng 14-speed transmission requires steady and precise techniques. When starting off, first release the clutch and then gradually apply throttle—shifting around 1500 RPM makes for the smoothest gear changes. Before climbing a hill, downshift one or two gears in advance to prevent engine strain. Use lower gears to control speed when descending to protect the braking system. For long-distance empty hauls, higher gears save fuel, while heavy loads require gear selection based on cargo weight to avoid engine overload. Don't force the shift—apply gentle pressure; any grinding sensation may indicate synchronizer wear, so get it checked early. Frequent mountain driving sharpens reflexes—anticipating road conditions is key.
