just picked up a 2000 gtp and no drive no reverse tranny has a whine noise till put in gear previous owner had pan dropped and fluid filter change at that time the mechanic found 2 dime sized pieces of metal in the pan anyways they put new fluid and filter in it and fluid was clean he drove it another 3k miles and now the new tranny fluid looks like diesel oil so im guessing its burning..., I know its toast but just wondering what has happened to it what could those metal pieces might be off of and he said it would slip and he would give it a little gas and it would slam into gear to add to the equasion. thanks for the info guys any bit helps
