What causes difficulty in shifting gears for Dongfeng Tianlong?
1 Answers
The reasons for difficulty in shifting gears in Dongfeng Tianlong are as follows: 1. The positioning component of the gearshift lever's ball head fails: The gearshift lever can rotate freely around its own axis, making it impossible to accurately control the gear position; it may also be due to wear on the spherical working surface at the lower end of the gearshift lever, preventing it from controlling the shift fork or the shift head's groove, making both engaging and disengaging gears impossible. If it's the first case, the issue can be resolved through repair; if it's the second case, the gearshift lever needs to be replaced directly. 2. The clutch fails to disengage completely while the transmission's shifting mechanism is operational. This fault can be resolved by adjusting the clutch or replacing some clutch components to ensure the clutch has appropriate free play and separation clearance. 3. Pressure plate failure: This may also cause difficulty in engaging gears. The issue of hard shifting when the engine is hot is mostly caused by long-term wear of the pressure plate or aging of the separation fingers, requiring replacement of the pressure plate. This repair is relatively complex, as the entire transmission must be removed to replace the pressure plate. 4. Issues with the gear selection or shift cables: Manual transmission cars still use two cables for gear shifting during operation. If either of these cables breaks, it can lead to gear shifting problems. 5. Poorly run-in components: If the components inside the transmission of a new car have not been properly run-in, some gear components may be stiff, causing difficulty in shifting. This situation will naturally improve after a period of running-in. 6. Transmission oil issues: If the transmission components lack oil or the oil quality is poor, shifting will feel stiff. Transmission oil is similar to engine oil and requires regular checks and timely top-ups.
