Jeff, the one part of your question no one else has answered yet was whether the ring gear was swapped to the opposite side for the DeLorean application of the Renault transmission. I can answer that - the ring gear can not just be "flipped". The DMC ring and pinion gears are unique, and to add to the problem the case they fit in is also. Several years ago, with the aid of a top transmission specialist, I tried to modify a front-wheel drive transmission by first flipping the ring gear (which isn't even close to working), then by installing a new DMC ring and pinion. Even with machining the case they would not fit. You can easily use the front wheel drive trans if you can find one - the trick is to re-use the ring and pinion case and gears from your old trans as it separates from the actual transmission housing. And no, I don't have an interchange for the filter either - yet. Hope this helps. -- Darryl Tinnerstet Specialty Automotive McCleary, WA
