I am looking for a convenient source to test the oil in my GETRAG.
Here's the story:
I had a trip breakdown last October. A midwest Dodge dealer installed a rebuilt GETRAG and put GM 75W-140 synthetic oil in it
. I now know this is bad. I just drained it and replaced with Mobil1 5W-30. The drained oil has roughly 3K miles and looks like gold (brass?)paint :{ . I'd like to get it analyzed.
