Help - Whistling sound with cold engine?

[BigPoch]

Hi Guys,

 

I get this annoying whistling sound every time i start the vehicle from cold for about 5-10 mins until oil/engine heats up.

 

Is it the diff or a belt?

 

Thanks,

I sometimes get this on cold mornings, I've always put it down to transmission noise.

I just keep the revs low until it's warm 👊

Is it the transmission dying ? Should i add some molyslip at next service?

I get this sometimes a well , new oem DMF, new oem clutch , gearbox tip top, so not sure what it is seems to go away for days/weeks then randomly comes back

I've changed my fluids every year and added molyslip, like kbad says, it's not all the time, I don't drive mine hard until it's warmed up anyway so maybe that's why I notice it less.
