Hello,

I have noticed that my automatic gearbox is working noisy.
The gears are changing smoothly without any problem but I can hear the gearbox.
Where is the problem?

Thank you,
Arek

What year is the car? Do you know which automatic gearbox is fitted? How many miles/kilometres has it covered?

Is it the gearbox or the power steering? I get some whining noise every now and then, on the left-front side of the car (sound like coming from under the dashboard), and since mine is a 2015 GT with left hand side steering, I was thinking this could be from the power steering...Gearbox has not crossed my mind until now...

UPDATE:

After analysing the sounds I think it isn't the gearbox.
On Neutral gear I accelerated the engine and that noisy sound increased.
Do not know what is it.
It looks like a faulty bearing? I don't know. I didnt replaced the alternator belt yet.

If the noise increases without the car moving then it must be something to do with engine. There are many items that could be causing the noise if it is something on the auxiliary belt - alternator, pulleys, etc. A stethoscope would help to locate the source.

What kind of noise? How loud? You can hear it only while accelerate in first or second gear? Try with A/C off. Compressor can be the source, but this is not necessary sign of any fault.

Take off the aux drive belt and see if the noise goes....sounds more like alternator/aircon pump..could also be water pump but that will be hard to test

Hi,

thank you for advice.
I personally can't do it without instruction. I am not a car mechanic.

How long should I keep the engine running until the engine gets overheating?

Thanks,
Arek

Water pumps are mostly driven by the timing belts nowadays but if its a 1.2 it may well be driven by auxiliary belt running for a few minutes without the belt wont do any harm.

I believe this is a turbocharged engine so could it be turbo-whine? If it is a developing turbo problem then get it looked at immediately. A common problem is that the oil feed and return pipes to/from the turbo become blocked-up with carbonised oil. This happens when engines are switched off immediately after the engine has been worked hard without allowing the turbo to cool down slowly and the oil 'cooks' in the feed and return pipes. This starves the turbo of lubricating oil and causes turbo failure. It is much cheaper to get the pipes changed before this happens.

Hi,

thank you for your answer.
I am trying to let engine running for 30s to 1 min after longer drive.
The problem is Auto-Stop function where the engine is stopped automatically.
I am trying to switch this function off as often as I remember.
But I think/believe designers of this car took it into consideration.

EDITED:

I have a garage appointment next Saturday booked, for auxiliary belt replacement so will see what is going on with this sound, I believe.

Regards,
Arek

If it's the end of your journey just unclip your seatbelt before releasing the clutch pedal as this will disable the stop / start system.

Reversible alternator is combo alternator/starter. You can find it in e-HDi models. BlueHDi have classic two device - starter and alternator - again.
This reversible model is designed to reduce weight and vibrations due to elastic connections by belt - no gearing with flywheel.
