Yep - everybody says that.
Unfortunately, from what I've heard - it's not compatible with that Valvoline synthetic that's in the pumpkin presently. Friday the truck's going to H.B.Trans and they'll flush it out - put the normal hypoid in and, of course, the GM posi additive.
You know I can't just have a simple fix and there has to be much blood-letting, teeth gnashing and screaming tears before everything settles back down anyway.
