Hi all
i have a strange whirring noise seems to be coming from the gearbox, if i put my ear to the gearleaver i can hear it more.
i changed the oil and put motul in last week and its made no difference. gearbox is working fine.
If i am coasting with the clutch in, or driving as normal the noise is always the same, any ideas would be very helpfull,
thanks
jamie

 

How loud is the noise,? do you really need to stick your ear to the gearknob to hear it, this will amplify the sound, all gearboxes make this sound to some degree.

 

Driveshaft noise ?

 

Hi
yes it is loud enough to be heard in the car, a constant metalic sort of whirring, but it seems to stay at the same level of noise starting from about 3000 rpm but the sound doesnt change even with higher speed or revs, i dont think its drive shaft, it seems to be coming from the gearbox , i thoght it might be the diff but like i said the noise doesnt seem to change with speed or revs. gearbox is working fine,not jumping out of gear or notchy, 50,000 miles done
thanks

 

change the oil.. check the old oil for metal bits.. no metal = no wear taking place, put new oil in and keep driving

imho there is no point repairing a box just live with it and replace when it goes pop

 

Hi,

I've got a similar issue with my car at the moment. Both an independent and Honda mechanic have had a look and think its the bearings in the gearbox. They had the car up on a ramp and ran it so i could it and it was much louder from that perspective than sitting in the car!

The key difference is that the noise in mine changes frequency / increases with more speed.

 

Yes i changed the oil to motul and the old oil i took out was clean so all looks ok. thanks a lot for your replies

 

Interesting, my car has had the same for 2k miles, because it is out of warranty, Honda offered a replacement unit if I paid 60% of the cost.

Sounds as though this may be a feature on the car

 

All gearboxes get noisier with age. It's just a fact of life. It's a bit odd that you say yours is not speed related. If you think about what's happening the faster the engine runs the faster the first motion (input) shaft is spinning. If the noise is coming from the bearings that support this shaft it's pitch will change with engine revs.
Same applis for the leyshaft bearings.
Noisy Output shaft bearings will vary in pitch with road speed.

Try this:

Start car and rev the engine to about 3000 rpm or where ever you can hear the noise. depress the clutch. If the noise stops it's most likely input shaft. If you can't hear it at all its somthing to do with the output shaft. If you can hear it all the time even with the clutch pressed it's not the gearbox.

 

The noise on mine stays with the clutch depressed, so you would actually think it's not the gearbox. As i am not very mechanically minded, can you clarify that point for me.

i.e can it be the outshaft bearings, and is this a job that a gearbox specialist could fix.

I had a quote to "fix"the noisy bearing and fit a new clutch for around
