When it comes down to gearbox issues, your problem could be of an electronic, mechanical or hydraulic nature. With the advancement of technology, you need proper training and experience to handle the complexities of the gearbox.

Also, gone are the days when transmissions simply used to Manual or Automatic. There's a relatively new entrant called the CVT (installed in most cars these days) that gives you a smoother driving experience.

Is it as complex as it sounds? Yes. So, just leave it to the experts.
