Difficulty in Shifting Gears in a New Automatic Transmission Car

[Tucker]

Difficulty in shifting gears in an automatic transmission car could be caused by personal operation factors, clutch factors, transmission factors, etc. Operation factors: Incorrect operation by the driver, where the speed and gear do not match, can lead to difficulty in shifting gears. This can be resolved as the driver gains experience and becomes more proficient in operation. Clutch factors: Rust on the transmission's first shaft can prevent the clutch driven disc from moving normally, leading to poor return and making it difficult for the gear to engage properly. Clutch failure can result in insufficient clutch separation travel, causing incomplete clutch separation and difficulty in engaging gears. In such cases, it is necessary to adjust the separation travel at a repair shop. Excessive self-locking force in the clutch gear can make it difficult to shift in and out of gear, requiring adjustment of the clutch cable and gear stop lock at a repair shop. Deformation of the transmission plate in the clutch pressure plate assembly due to certain reasons can lead to poor separation, resulting in difficulty in shifting gears. In this case, it is necessary to replace the pressure plate with one that matches the original car's quality. Transmission factors: Old transmission oil needs to be replaced. If not replaced in time, it will reduce the lubrication effect, making it difficult to shift gears. In a new car, the transmission components may not have reached the optimal running-in state, leading to difficulty in shifting gears. This situation will improve after a period of running-in. In colder temperatures, the viscosity of the gear oil in the transmission may not reach the optimal state, reducing the lubrication effect and causing difficulty in shifting gears.
