131 diesel gearbox

[124 man]

Has the 131 diesel a fiat or zf gearbox ?

I think it is a different box to the petrol models so I'm guessing it's the ZF box but I have never owned one (not quite)

i can tell you about fiat 132 diesel, and i'm pretty sure it's the same story with 131.

gearbox is exactly the same as in petrol powered version, only the bellhousing is different. knowing that the only diference between 131 and 132 gearbox is extended bolt on shifter on mk2 131 2door and mk3 supermirafiori, i believe that 131 diesel used same gearbox as petrol powered versions.
in fact, i distinctly remember that gearbox in my 132 diesel had casting on the side with 131aa, or 131ab on  it.
