While many motorists usually do regular maintenance checks on their engines, radiators and other components, the gearbox tends to be a relatively understated part of the process but it is as important as any other component of the drivetrain. After all, it is the mechanism that harnesses the power and translated it into motion. So maintaining it is imperative to your cars ability to actually move.

It is therefore important to keep a sharp eye out for the signs suggesting your transmission is in trouble and in dire need of repairs or a complete rebuild even. We have assembled to following list so that you know when it is time to do so.

Fluid Leakage and Discoloration

Leaking transmission fluid is a definite no-no. Your transmission needs to maintain a certain level of fluid for it to operate smoothly. Losing fluids unnecessarily is about the same as bleeding out. A lack of adequate fluid can inhibit gear changes.

It is not just leakage that you must look out for. Fluid will go bad over time and need replacing. Good fluid retains a pinkish red colour and a sweet smell while bad fluid looks burnt and smells that way too. It usually appears to be either dark brown or black. If you replace that with new fluid and still find the transmission to be faulty, you will know there could a worse issue to deal with.

Noisy Neutral Mode

If your transmission cannot seem to shut up even in neutral mode, it is clearly crying for a major repair or replacement. You may also be hearing unfamiliar noises while shifting through the gears. If so, waste no time in showing your car to a mechanic.

Grinding and Shaking

If you are shifting to new gear and feel a shudder or grinding noise coming from below, there is trouble a-brewing. Often times, this is a symptom associated with manual transmissions. However, it is not unheard of in automatic transmissions either.

More Weird Sounds

Whining, clunking, and humming are just a few more sounds that are your transmissions preferred language for letting you know that something bad has come up. A well-functioning automatic transmission should be producing no noise whatsoever. It will only make noises when it is fussing about some difficulty.

Lack of Response from the System

Perhaps more obvious sign out of all the others is that your transmission can no longer respond to your input. This tends to happen sooner in a manual transmission that with an automatic. With an automatic, the best way to find out is when you set it to Park or Drive. If the car is taking way too long to respond to either one of those settings, it is high time to have that looked into by a specialist.


So now you know when it is time to invest in some repair work or a brand new automatic transmission for your ride.
