Searching has turned up a major problem with '06 model year Dmax trucks.
How many Lb7 owners have the same problem and what are the fixes that have worked?
Thanks for the input.

so no one with an LB7 has had leaking tranny hose fittings? I guess mine's a fluke. Are the stock hoses still the best choice for replacement?

We have two 06 Dmax's in GMC dually's here at work. The first one developed the leak early on and the hose was replaced 3 times before a better replacement was installed the 4th time which seems to have fixed the problem. The other started leaking at 1ok was replaced and has been good so far. I think they got it right now? The hose leaked right at the crimp between the hose and the metal fitting.
