So a few weeks ago after getting my trans cooler lines replace the truck started to mark its territory. Then it got better, now it only leaks after a long drive, however its definitely trans fluid because its red, and its coming from the smaller of the two inspection covers on the bellhousing, the one closest to the pan. i gather this is the front pump seal that has finally warped and gone out. Does this sound correct? Should I get this serviced at the dealer or have a shop do the repair?
