I have a 1995 Ford Explorer 2WD with a manual transmission. I believe the transmission is actually made by Mazda. The vehicle has 100k miles and shifting is getting a little notchy/hesitant, even though the transmission has received regular oil changes and the clutch is quite new and in good condition. The owner’s manual calls for "Mercon" or Ford part number "XT-2-QDX". I've had good luck in other vehicles going to aftermarket oils (specifically in Hondas, Honda MTL to Redline MTL) and am looking for a similar improvement in shift quality. I just can't believe there's not something better out there for manual transmission than ATF. Thanks!
