I just purchased a 2007 Yukon 2wd with a 6” Procomp lift on Saturday the 11th. Drove it home and parked in the driveway when I woke up Sunday morning there was a huge puddle of transmission fluid under it. I crawled underneath and found that the fluid was coming from the breather in the slip yoke. Since then it has been to three dealers (It only has 26,000 miles and is still under warranty). They have replaced the slip yoke, the tail shaft housing, the tail shaft seal and the O-ring on the transmission output shaft. At this point the dealership is telling me that because the vehicle is lifted with the nose slightly higher than the rear and I park in the driveway that is angled nose higher than the rear that it is normal for the transmission to leak out of this breather. It does not leak when parked on flat ground but if I pull into my drive way and the transmission fluid pours back into the pan from the converter it starts leaking. I’m not sure what to do next. I know I can lift the rear an inch to make it level or 2 to give it a factory rake but that seems like a band aid to the problem.
Does anyone have experience with this and have a suggestion?
Can I JB weld the breather closed without hurting the transmission?
