General signs:
*Check Engine Light (CEL): The CEL may illuminate, indicating a faulty transmission speed sensor.
*Rough Gear Shifts: The transmission may shift into gears with jerkiness or delay.
* Towing or Slipping: The transmission may slip or fail to shift gears properly, resulting in towing or slipping.
* Increased fuel consumption: A faulty sensor can cause the transmission to operate inefficiently, increasing fuel consumption.
* Unusual noises or vibrations: The transmission may make unusual noises or vibrations due to a faulty sensor.
Specific symptoms for different types of gearboxes:
Automatic transmissions:
* Slipping at the start: The vehicle may slip or accelerate slowly from a stop due to inaccurate engine speed data.
* Shift Delay: The transmission may delay shifting or shift into the wrong gears.
* Gear Lock: The car may get stuck in one gear due to a faulty sensor.
Manual gearboxes:
* Difficulty shifting gears: Shifting gears may be difficult or impossible due to inaccurate engine and transmission speed data.
* Gear Grinding: The transmission may make a grinding noise due to untimely gear shifting.
*Clutch Damage: A faulty sensor can cause premature clutch wear due to improper engine and transmission connections.
Continuously Variable Transmissions (CVT):
* Speed Fluctuation: Vehicle speed may fluctuate due to inaccurate engine speed data.
* Harsh accelerations: The CVT may accelerate or decelerate suddenly due to a faulty sensor.
* Burning smell: Excessive load on the transmission may cause a burning smell.
