      will
      Not sure about ratios, Will, but I'd imagine different.

      B5Q box looks similar to B3 / B4Q, bellhousing is the same, but that's about it. The transmission-to-subframe mounts are completely different.

        small detalj skills: speedsencor( may not wire) hydolic clutch( may not wire,some trannys have wire) the trannymounth arent the same( may be interchangable) and the inneryoke arent the same, you have to change them so they fit the propchafts.... audi vw are some pain in the *** , they have ALOT diff part in the same car, in the same year

            No Audi A4 was fitted with cable operated clutch...

                  Show me a quattro with cable clutch.

                  And yes. It does fit. Make sure the final ratio is the same as in the old box, otherwise you need to change the rear diff too or combine the 2 boxes - plenty of work.
                  Gear ratios may differ more or less. They probably do and family album can tell how much.
                  They're both 01a series so you can just swap the mounts.

                    From memory, the A4 quattro tranny casing doesn't have the threaded mount holes in the same position as 80 quattro...
