What auto transmission gear oil did ford cars use?

ATF is somewhat uni.





The older fords spec'ed type F, newer ones specs dextron/mercon. The dex/mer fluid can be swapped out with each other like dex/mer, dex/mer II, etc.





GM always spec'ed dex/mer for their trannys, but alot of high performance guys and racers in the 70's and 80's would use type F in their GM auto transmission cause it would give a harder shift between gears.





The reason for that is type F don't have as many friction modifiers in it as dex/mer does.





On the other hand, alot of ford guys would run dex/mer in thier ford auto transmissions that spec'ed type F, cause the dex/mer would help the trans to live longer, shift smoother, etc.What auto transmission gear oil did ford cars use?

You MUST know which transmission you have. For many yeas Ford only used TYPE F. When they began buying other car companies and outsourcing their parts manufacturing, that changed. You can find Fords that use TYPE F, MERCON DEXTRON AND MERCON DEXTRON II.








If you need to be sure, look up the transmission code on the ID plate for your vehicle and call the Ford dealer near you or a good auto parts store. IF you can not find the ID plate, Copy the vehicle's VIN # and then call either one, they will be able to tell you which digit identifies the transmission and then they can look up the correct information for you.





I hope this helps.
