Hey I'm planning on changing the transmission fluid in my 5 speed so I did some searching and decided that 3 quarts of mobil 1 synthetic ATF with 4oz of motorcraft friction modifier is what I need. No auto parts stores seem to carry any type of friction modifier though, so I went to the dealership and they sold me a bottle but they also said that I shouldn't use ATF in a manual tranny. They also tried to sell me some fully synthetic manual fluid for 17 bucks a bottle though. The mechanic also said that you didn't need any friction modifier either. Will I be ok with the ATF and modifier? Do these guys not know what they're talking about?
