What makes a gearbox whine?
The intrusive noise known as gear whine is caused by vibrations generated by gears as they mesh as a result of imperfections caused by design, loading, temperature effects, and manufacturing variations. Gear whine does not have to be loud to be a problem.
How do I stop my gearbox from whining?

- Use High-Precision Gears.
- Use a Better Surface Finish on Gears.
- Ensure a Correct Tooth Contact.

- Increase the Transverse Contact Ratio.
- Increase the Overlap Ratio.

In synchromesh transmission the pair of gears which has to be used for final transmission of output first bring in frictional contact with the synchromesh device and then final selection of the appropriate gear takes place. It usually comes with the 5-speed 1-reverse manual transmission configuration for example- Maruti Suzuki swift.
What causes an inefficient gearbox synchronizer to work?
Inefficient synchronizer performance can be caused by either a problem in the transmission, or by a separate clutch issue. While cone-like-synchronizers are simple and reliable, they rely on friction to function, and as such, the blocking rings degrade over time.
When does a bad gearbox make a clunking noise?
Commonly, the noise is loudest when letting out the clutch when taking off from a stop. Alternatively, if the rear transmission is bad in a rear-wheel-drive vehicle, the noise will occur when letting out the clutch in reverse as the tail shaft of the transmission rises up and slams back down. Broken mounts may also result in a clunking noise
Why does my car make a grinding noise when I change gears?
The problem makes it difficult or impossible to change gears and is accompanied by a grinding noise.

Fixing it could be as easy as adding or changing the fluid.
