ATF is considered a high pressure lubricant. Many cars, especially high end cars, run ATF in the stick shift transmissions and differentials. I have seen too many cars that have been serviced at "Quick Lube" type shops were the applicable ATF has been replaced with GL type lubricants and components have failed.
