Couple of days ago I posted about my mate was looking to get a MK5 ASTRA 1.9 CDTI sri (150) and we had found one but turns out the gearbox is on the way out. I know there prone to goin but what about the Vectra's gearbox. Somebody told me they use an F40 gearbox instead of an M32 that the astra uses. Do the F40 boxes last longer, are they stronger? Any info would be gratefully received. Thanks in advance, matt.
