I have a 2008 fiat ducato with a 160hp 3.0 Iveco engine running an M40 gearbox. unfortuantly for me the gearbox is dying .. 3 gear crunch and 6th gear whine. So im looking to replace it. I have found a gearbox which looks the same but its from a 2016 2.3 fiat ducato- its advertised as an M40 box ... but my concern is that it
A- might not fit
B- drive shafts might differ
C- might not handle the 3.0 engine?
I know they might seem like daft concerns.. But it appears having a gearbox replaced in 24hours is a better option than having my gearbox removed - sent off.. repaired when the specialist can fit it in, sent back to the garage and then the garage installing it when theyre next free.. I expect this method to not see my van back for about two weeks ... ( just incase you wander why i dont get mine removed and repaired etc)

If someone knows what years of M40 gearboxes would fit a 2008, please let me know , thanks
