ACDelco p/n 19351882 aka 10-4105 synthetic PTU lubricant used for my Buick Regal AWD. The PTU unit is made by AAM. Also used in the 2017+ Equinox etc from my research. I posted a DIY on changing the fluid on the Buick forum.
The bottle states it is a 75w-90 EP lubricant and has a list price of over $90/qt. I picked one up from my dealer for $55. The capacity is listed at 0.69qts. My goal of the VOA was to see if I could substitute a less-expensive commonly available gear lube. Thoughts?
