Transmission Output Speed Sensor Malfunction?
1 Answers
Due to damage to the automatic transmission input shaft speed sensor, a fault code appears. The following are symptoms of a faulty sensor: 1. Automatic disengagement: During power transmission, the axial force generated by the meshing sliding gears or coupling sleeves exceeds the locking force, causing the gears to automatically shift to neutral. This results from component wear, housing deformation (reducing axial force), insufficient gear meshing length, or failure of the self-locking mechanism (reducing locking force). 2. Gear disarray: Excessive clearance in shift lever components leads to imprecise gear positioning, lever vibration, and difficult shifting. 3. Noise: Causes include excessive gear clearance, impact from housing deformation, bearing failure, insufficient/inappropriate lubricant specification, oil leakage, aged oil seals, housing deformation, or shaft bending.
