I changed from a manual to an auto for reasons beyond my control and I have been pleased with the results. It is years since I ran an auto and I was expecting a bigger milage hit.
That depends on the specific automatic transmission though. When I managed to get into the 50s mpg, that was a lot of coasting (engine on), and my transmission does not like coming back into D while rolling - there is a lot of slipping and refilling the hydraulics. Now when the trans is cold there is erratic shifting, and I am not doing any more coasting in it as I think it has worn it badly. If it breaks on me, I will either convert to a manual, or get another TDI with a stick shift.

I think my old Mercedes diesel with a rear pump would be a better automatic to hypermile, although the mileage would be less than spectacular compared to my TDI.
