Please help I am getting nowhere fast. I found an 1985 Audi coupe with a 5 cyl engine does this make it a 5000 and is the trans useable? Everything I read says to use an Audi 5000 trans but this car is a coupe. I found on the web a list and from that list I believe that the trans is a 093. Can I use a trans out of a 4000 what is the big difference between the 4000 and the 5000 any light you can shine on this would be greatly appreciated thanks Steve
