Here at YB Components we provide a gearbox repair service for our UK customers. It includes an inspection and report completely free of charge, and all repairs are carried out under strict control. We replace seals and bearings, and source any replacement gears from the original gearbox manufacturer wherever possible.
Now let’s take a
look at some of the most common gearbox problems and their solutions.
Vehicle Doesn’t Engage When in Gear
If there is a
delay in the vehicle’s transmission or it doesn’t engage at all, there could either
be a problem with fluid degradation or there could be a computer system
problem. A gearbox fluid change should obviously solve the first issue, while
the second may require a full reset of the vehicle’s computer.
You can reset the computer by disconnecting
the battery for around half an hour. If problems persist after these measures,
then you should have a qualified transmission mechanic look at it.
Shaking or Grinding When in Gear
should operate smoothly when shifting gears, but any shaking or grinding could
indicate a problem that could get worse if ignored. The most serious issue that
might be occurring is that the gearbox has damaged gears, which will require a gearbox repair service as soon
as possible as it will only get worse with continued usage.
Clunking or Humming Noises When in Neutral
or sometimes whiny humming noises coming from under the vehicle when in neutral
could indicate an issue with the transmission. It is likely to be a simple
fluid issue again, as the gears and moving components create more and more
friction as the lubricant degrades.
If a fluid
change doesn’t help, then there may already be internal damage which will
require the attention of a qualified transmission mechanic.
can present a very serious safety problem and there isn’t anything you can do
about it yourself other than get it in for a gearbox repair service. It is
probably an issue with the vehicle’s computer not sending the right signal when
you shift gears, so an expert’s help will be required.
Leaking Transmission Fluid
If you discover
dark patches of fluid under your vehicle then you probably have a leaking
transmission fluid problem. This can be a very serious problem so try and get
it fixed as soon as possible because leaking fluid can quickly result in a
complete breakdown of your transmission.
Also check the transmission fluid level,
especially if the vehicle does not park in the same spot over and over again
which would help you spot the leak on the floor. Transmission fluid should not decrease
over time or mileage, so a lower level than usual indicates there is a leak.
Catch this problem early via a gearbox repair service and it shouldn’t be very
costly at all as the leak itself is an easy fix.
