A gearbox, also called transmission, is a mechanical device which transfers power from one part to another. It also regulates speed and torque between car components like a load and a motor.
Simply put, a gearbox is a collection of gears connected to the wheels and shifted to manage speed and torque while driving. The gears are arranged in different patterns to provide various speed levels while maintaining the engine performance.
Due to its constant use, wear and tear can cause various types of gearbox problems. Considering its role in directing power from the engine to the wheels, it is necessary you never overlook them. Understanding what these issues are is essential for timely identification and resolution to maintain the optimal performance of the gearbox.
List Of Common Car Gearbox Problems
-
Insufficient Acceleration or Throttle Response
This problem leads to a delay in the car's acceleration. This can happen due to a faulty clutch, exhausted plates, worn-out clutch springs or air in the fluid passage.
-
Transmission Fluid Spillage Under Your Car
Transmission fluid is a bright orange liquid required to lubricate the gearbox. It can spill and accumulate under your car because of excessively high oil levels in the enclosure, damaged oil sealings, loose nuts or bolts or a crack in gear sealing.
-
Grinding Noise and Buzzing During the Gear Shifts
One of the most common gearbox problems is the shaking and grinding of your car during a gear shift. It can happen due to a dry rear wheel bearing on the main shaft, damaged speedometer drive gears, insufficient lubrication because of worn bearings and shaft, or excessive recoil in a gear train.
