What Causes Gear Confusion in Automatic Transmission Vehicles?
1 Answers
The causes of gear confusion in automatic transmission vehicles are: 1. Wear and looseness of the transmission fork shaft groove and positioning ball, as well as excessively soft or broken positioning springs, resulting in positioning device failure; 2. Bent shift fork, excessive wear, or loose fixing screws, preventing gears from meshing properly; 3. Conical wear of gears, gear rings, or gear sleeves along the tooth length, causing disengagement due to axial forces generated during operation; 4. Wear and looseness of transmission shafts or bearings, leading to jumping and axial movement during shaft rotation; 5. Failure of the gear retaining nut or snap ring on the transmission shaft, causing gear movement; 6. Loose or disassembled synchronizer lock pins, resulting in cone surface failure.
