What Causes Difficulty in Shifting Gears in Trucks?
2 Answers
Here are the reasons why it's difficult to shift gears in trucks: 1. Operational Factors: Incorrect operation by the driver, where the speed does not match the gear, leads to difficulty in shifting. This requires the driver to gain experience and become proficient in operation, after which the problem will naturally resolve. 2. Clutch Factors: (1) Once the transmission rusts, the clutch driven disc cannot move normally, leading to poor return and preventing the gear from engaging along the normal path, thus causing difficulty in shifting. (2) Clutch failure results in insufficient clutch separation travel, leading to incomplete clutch separation and inability to engage the gear. In such cases, it's necessary to go to a repair shop to adjust the separation travel. (3) Excessive self-locking force of the clutch gear makes it difficult to shift in and out of gear. This situation requires adjustment of the clutch cable and gear lock at a repair shop.
I've been driving trucks for over ten years and often encounter difficulties shifting gears, which is mostly due to clutch problems. Worn clutch plates or insufficient pedal engagement can cause the gear lever to get stuck or become hard to push. Additionally, old or improperly changed gear oil, such as when it deteriorates or lacks lubrication, increases friction between the gears in the transmission, making shifting feel particularly strenuous. Sometimes, cold weather can also make initial gear shifting tricky due to high oil viscosity. I remember once during a long-distance trip, the gear lever just wouldn't go in no matter what, and it turned out the synchronizer was worn out and needed immediate replacement. So, it's important to stick to regular maintenance schedules, check oil levels and component conditions in time, and not wait for major issues to arise before fixing them, as this could affect driving safety.
