There are 3 main symptoms to look out for when diagnosing a manual gearbox:

  1. Jumps out of gear
  2. Gears grating
  3. Noisy

Gearbox: jumping out of gear

When a vehicle jumps out of gear, 99% of the time this is due to a gear being worn. Unfortunately, over time the contact pattern of the gears wears down and the 2 gears no longer mesh correctly. The most common cause of this symptom is high mileage and simple wear & tear.

This is the most basic symptom to diagnose because when you drive the vehicle, the gearbox will jump out of gear.

Gears grating

This happens when the synchronizers (part of a synchromesh manual transmission that allows the smooth engagement of gears) or synchro-rings are worn and they do not lock onto the gear. When trying to diagnose this fault, be aware that the clutch can also cause a grating into gear.

We determine the difference by which gears grate when engaging. If the grating occurs when engaging 1st gear or reverses while the vehicle is stationary, the grating is usually caused by the clutch. If the grating occurs in any other gear while the vehicle is moving, this is usually caused by the synchromesh inside the gearbox.

Gearbox noise

Noise is by far the most difficult problem to diagnose. The main causes of noise can be worn/noisy bearings; gear meshing (wear & tear); lack of oil (Burnt Gears) or Excessive play on the gears/shafts.

When diagnosing a noise in a gearbox, it is important to test the noise in various states before coming to a conclusive diagnosis.
