have a 96 4x had crank replaced since then trans leaks on and off, at first thought it was coming from inside bell housing, further inspection looked like breater tube, dried it off filled it up and still leaking from somewhere, took in to a shop, they cleaned it up and ran it on a lift, no leak drive or park, took it down and drove it around town, no leak, shop told me they couldn't find leaks anywhere, got truck back no leaks for a week, ac compressor seized up on me so i parked it for a month maybe two, finally got ac compressor fixed, started leaking again, this time looks like breather tube again but it's running it dry, had to add two 1/2 quarts in a couple days any thoughts
