Hi guys, I have a 2002 Fiat Ducato 2.8 JTD Motorhome, I want to change the gearbox oil, I know how to do it but would like advice on what oil to use and how much.

2.7 litres . I'd drain & check though .
SAE 75W-80 Think i might have used 75W-90

That’s great, thanks, trouble is I’ve had a bit of a leak from the drain-plug so draining the oil is not going to be a good indicator of how much there should be in it.
