Mike, If you get your coach towed remove the driveshaft at the differential end not the trans end. It would have been easier to drop the diff end and just pull it out of the trans, but a pan under it usually drops a little trans fluid.
Fred, that piece looks like their idea of a manifold, can you get the lines to release? Usually if you can get them out take and cut off a half inch clean the line real good and insert it back in.
