||I misread the receipt. I was charged for 2 quarts of the 1XGPPOP differential oil and 5 quarts of the AA100P A transmission fluid. I assume one unit is one quart. I guess, since my grandson is accustomed to driving newer cars, that what he reports as "hard shifts" must be normal. It is interesting that the description of the transmission service is: "Full synthetic transmission service 12 quart".
Once a service provider loses your trust, you question everything!
