ECZ transmission goes with DUR & EUS final drive 3.7:1
FUL transmission goes with EUS & GME final drive 3.7:1

MikkiJayne thank you for this answer. So for the basic function this would be a feasible swap. Next question then is if I should worry about any installation issues with mountings, electrical connectors or similar in mowing it from the A6 2002 to my A8L 2000. Also this is a used transmission said to be working before removal but I am planning on rebuilding it. Any recommendations on where to get a rebuild kit and what parts need replacing?
