Ram tranny problems

Oh and the metal shavings in the drain pan may or may not be from my trans. My brother just informed me that the pan I used was also under his car draining the diff fluid. He blew the rear end apart and didn't brake clean the pan. After I drained the trans fluid into our container to take it in I seen ball bearings and that's when he told me. I didn't even check to see if the pan was clean I did it in the dark with a little flash light. I know I just made it more complicated by not checking after his lack of cleaning.
