Its being done at Pohanka Isuzu in Marlow Height Md. This is the 1st time taking it to a dealer since I got it back in November,so I cant comment whether they are good or bad. It seems they dont mind doing warranty work as long as it's approved by Isuzu. I will try to get them to use synthetic trans fluid, though I wont a warranty anyways when it comes out. I got to check into that.
