Mobil LV HP ATF

Where are you buying Mobil LV HP ATF? Our oil supplier has none, barrels or bottles. Dealers are calling me begging to let some go. One dealer a few hours away sent their driver with a couple of buckets just to get a vehicle out of their shop. There was a black label and blue label bottle, one of the countermen here says a bulletin came out a year ago that stated not to use the black label. I do not remember seeing such a bulletin. Aftermarket is gouging on the quart bottles $14 each, bullshit. At some point warranty will stop paying the difference.
