Exactly as chrisgixer says, only ever available on the Y25DT (the BMW common rail lump fitted to Opel only - UK got the rather naff, comparitively speaking, Y22DTH, 2.2DTi)
Therefore no software for anything other than the Y25DT, thus no good in any other car.
TD owners wanting a box change, as much as I hate the Omega manual, should change to a manual. Its a different car -*much* better MPG (a match for the 2.2DTi when chipped, economy wise), much more responsive.
If I were to buy another 2.5TD, and I have considered it, it would have to be a manual.
Yes, but remember Hans-V6, the guy from the Netherlands: his car had 5-speed auto and was definately 3,2 engine... :-/ It has been discussed but nobody seems to have the infinite answer to that question. I have never seen any other V6 Omega with 5-speed auto exept that one...
