Hi All,   I recently had the fluid changed on my powershift gearbox. The changing seems a lot better, but its developed a whining noise.

You can hear it even in neutral or park.

Would not using the correct fluid cause this, as I took it to an Auto gearbox specialist who only charged me £240 Inc vat and also reset the software in the gearbox.

Its more noticeable between 2&3k revs

Any help, ideas guys

Cheers

 

I would take it back to them to listen to it as they have worked on the box. Had mine done yesterday and as you say the oil / filter change makes a noticeable difference to the box.

Had mine done by my friendly Ford mechanic using Ford oil and filter.

Its the Getrag model.

Think I'll take it back and let them listen

I have also DCT450, before replacing something expensive, replace the gearbox oil+filter, I'm pretty sure the whining will stop.

Thanks guys

Had a good listen under the bonnet today while my wife held the throttle at 2k revs.

I put my ear on the airbox, and that seems where the whining noise is coming from.

Had a new power steering pump fitted last week so that's all quiet.

Any idea why the airbox is making a noise guys

Cheers

Take a look at the pic that i added, sometimes, the air box doesn't seat well with the adapter.

Thanks mate, will check that out in the morning.

Just wondering if when I had the gearbox fluid changed they didn't put the airbox back quite right.

Mmm 😀

Airbox has to be removed to fill the gearbox .
