Freelander whining going into 5th

Hi all I'm new on here, me and my wife have just brought a FL Td4 with 75k on it, it's got full service history and had most of that by landrover, tonight she noticed that when changing from 4th to 5th there is a whining sound, oly for about 10 second after selection, then disappears, no pressure on lever and clutch seems good, it appears to be coming through the head lever, I only picked it up on sat, it's still under the standard 3 month warranty I'm just scared that it's something major, anyone else had the same problem or know what it can be, please help

Re: 2005 td4 FL whining when selecting 5th
Update bit late I know, problem solved it was a gear selector bush or something like that, but now a new noise has come, it's like a drone/whine at around 45-60 in 5th but it appears to go when clutch is depressed or when it's knocked out of gear without foot on clutch, anybody have any ideas or expeirienced the same, thanks,

Your probably better off asking those nice peeps in the Gaylander section mate, most of them don't venture out of there much

Probably a bearing making itself heard - my D2 makes a slight whine in 5th too

I own a gaylander and im here.
And I am lost.
