I have a 98 a4 1.9tdi quattro that came fitted with a 5 speed gearbox. I have changed the gearbox, prop and rear diff for items sourced from a 6 speed a4 2.5 tdi quattro.
Old gearbox, 01A (I think), code DGW. Diff Code DAJ. (35:9)
New gearbox, 01E, code DQT. Diff Code DAK (37:9)
The gearbox mounts are different by the looks of it and it also looks like the 2.5 tdi and 1.9 tdi have differing subframes. I decided to go ahead and fit the gearbox and solve this riddle when I get to it.
So what I'd like to see please is the diagrams that show the various subframes and gearbox side mounts?
Will the I4 engine bolt to the V6 subframe if I source one?
or should I modify the existing subframe to take the new gearbox
Any experience of solving the same problem would be appreciated. Google has not been all that useful for me.
