Reasons for Difficulty in Shifting Gears in Automatic Transmissions

[OmarAnn]

Here are the reasons for difficulty in shifting gears in automatic transmissions: 1. Operational aspects: Incorrect operation by the driver, with speed and gear not matching. 2. Clutch aspects: Rust on the transmission input shaft, the clutch driven disc not moving properly, poor return, preventing the gear from engaging along the normal path, resulting in difficulty in shifting; clutch malfunction, causing insufficient clutch separation travel, leading to incomplete clutch separation and inability to engage gears. 3. Transmission aspects: Old transmission oil needing replacement; if not replaced in time, its lubrication effect will decrease, causing difficulty in shifting; new car transmission components not reaching optimal break-in condition, leading to difficulty in shifting; cold temperatures causing the viscosity of gear oil in the transmission to not reach optimal condition, reducing lubrication effect, thus resulting in difficulty in shifting.
