Have had this truck since 1994 and the tranny has leaked since 1999. Only leaks when it is real hot weather. Had it fixed about 4 years ago and they said it was front seal. Well that only lasted about a year and it started leaking again when it is real hot. A neighbor of mine said he thought it might be a crack in the pump that causes the leak when hot. I would like some input about this cause this truck even thought it is fairly old now still runs like a top. It has a 3.0l six cylinder auto tranny.Any help greatly appreciated!!
