It was of course a m46 not m47 but the dimensions are the same.
It drives so much better now.
still the same flywheel with a sachs diesel clutch for later 940's (1994-1998).
I didn't have a diesel prop m90 one so used one off a petrol car with the 4 bolt flange changed to a 3 bolt petrol one off the back of my dad's petrol m90.
You need a m90 diesel box with the gearstick assembly as that's particular to the diesel box being a bit longer than the petrol one.
All bolts together nicelt and the car is a lot nicer to drive.
First gear with the m46 was too short.
Plus if I wan to increase the power the box and clutch will be fine.
The m46 overdrive was working only when warmed up so it was no good.
you need the diesel gearbox support as that is slightly different. and a good m90 prop bearing as it's a lot thicker than the m46 one .
