I have a 2004 5.9 L Cummins with the 48RE transmission or whatever the transmission is. I replaced the lines, filter, gasket and I still have a slow leak coming from on top of the transmission and now it’s starting to puddle. I’d have a slow leak and have to have at a court every month but now it’s starting to puddle when it’s parked.. What could it be? I’m not sure if the dipstick runs to the top or a sensor. I just don’t have the capabilities to drop everything(motor and transmission) to figure it out. nor the down time because it’s a work truck for my business. That way I can put a game plan together and get it fixed. Thank you in advance Tim.
