I'm having similar issue, but probably worst. I don't have engine checklight but I have to fill up at least 2 qt. every 2 weeks or so. I drive about 300 miles a week. I noticed it there are residue at the bottom of the tranny, possibly leaks around there? It's not enough to make it drip or see wet oil, I just have no clue on where all the oil goes... No blue smoke from muffler and my radiator fluid is nice and green.
