Yes had handbook out so definitely needs fluid change. Its Rapido 7065, 17000 miles. We have owned it 4 years in August. The noise started a few month ago. It seemed worse when cold, when warmed up not as bad. So maybe when the oil has warmed & thinned and got round the gearbox might suggest it does need oil? Didn't know about oil for the clutch activation system should be checked every 2 years and replaced every 4 years till now. We have had it serviced but I'm guessing it's not been done. Also about transmission fluid. Hoping, it's these that need doing as opposed to gearbox going. Just want a price and know it's going to be sorted. Anyway other half will speak to fiat. Thanks
