Sound like a helicoptor under load??

[Timandclaire]

Today i've experienced a strange sound best described as like a helicoptor whirring,woop,woop sound lol

Anyone else experienced this? Only seems prevelant in one gear uphill under acceleration,goes away once the next gear is engaged.

Thanks

Have you checked the ATF level with the dipstick under the drivers seat, you need to use the right procedure, gearbox warm and in Drive -brakes and wheels chocks applied is best!
