This happened years ago and the car is long gone but always wonder if it would have caused any problem. Had a Saturn Vue which uses a Honda engine and transmission which takes Honda DW1 fluid. The Saturn dealer said they always use Dexron so that's what I used. Probably flushed and changed it 3 or 4 times with 15 quarts of fluid. Ran just fine afterwards and for a couple thousand more miles before I sold it. So did it do any harm to the transmission? Or even extend it's life?
