If you think the jiffy lube replaced the transmission, diff, or transfer case fluid, I would probably change those out sooner than later as odds are its not the right stuff. My first Focus wagon came with atf from jiffy lube in the mtx. Which was allowed by ford initially but after a year they spec'd a specific manual trans fluid.Okay, so VQ35DE is correct? I guess I don't understand his point. Does he want me to go back to the service center and tell the tech he's wrong? I don't really care what fluid goes where, as long as it isn't leaking...which it isn't...
