    Protection. Royal Purple Synchromax® is a full synthetic transmission fluid that provides superior wear protection for your Mustang's drivetrain. Synchromax® is formulated with Royal Purple's synthetic, proprietary Synerlec® additive technology, which offers improved shift quality over a wide temperature range and reduced gear noise. Use Royal Purple Synchromax on your Mustang's next fluid change for the cheapest insurance you can get against future transmission breakdowns.

    Better Shifts. If your transmission is notchy, rough, or loud but is mechanically fine, a fresh fill of Synchromax® can help smooth things back out. If you have a new Mustang or transmission, changing your fluid to Synchromax can keep your transmission working better - both now and later.

    Protects Internal Components. Synchromax® is fully compatible with all types of friction materials and offers excellent corrosion and oxidation protection without affecting the soft metals commonly found in manual transmission synchronizers.

    Application. Synchromax® is recommended for manual transmissions that specify an automatic transmission fluid or motor oil. Please note the T-45/T-3650 will take approximately 3.25 quarts to fill the transmission after a full transmission fluid flush.

      Better Cold Transmission Performance

      I have a 2012 Mustang GT, 6-speed manual. On cold mornings, the 1st to 2nd shift was a little rough until the car warmed up. I changed the trans fluid using Royal Purple Synchromax. That cured the problem. 1st to 2nd shift is now smooth all the time.

      Feels better than OEM

      Swapped this out on my MT82, still feeling a bit notchy when cold but that's sort of expected with this transmission despite a new shifter, trans mount bushing and blowfish bracket. Once warmed up, this helps make shifts feel like butter. I'd recommend on any MT82.

      What a Relief!

      I had an insanely hard time finding Trans Fluid that would work for my T-5. I know that way back when, it just called for Standard Mercon ATF but I soon found out they discontinued it and kept finding a bunch of different grades. The Royal Purple Synchromax was, not to be cheesy, the light at the end of the tunnel. It works perfectly and couldn’t be happier!

      Very easy to service on 2014 5.0. Just make sure your in neutral and the car is somewhat level (if using jacks) on both sides so it is is serviced to the proper level. Works like a charm, she just glides into gear now!

NOT A ONCE SINCE in my short throw Hurst and second to 3rd is smoother now after about a week of acclimating to the PURPLE GOO

      I had my dealer change out the fluid just before my 5 yr power train warranty w as s up so make sure they didnt see anything in the fluid since its notch when cold. I wish I did this sooner as the MT-82 is now so much smoother - I'm really impressed.

      Not for 2015 manual transmissions.

      Do not use in MT82 transmission. It has terrible cold performance, and even when warm, requires too much finesse to engage a gear. I fear I have done damage to my trans in the last 4,000 miles because of this. I don't know if there is a better option out there(BG Syncro Shift II), but I put Ford OEM dual clutch trans fluid back in, and it shifts great at all RPM's again. Seriously night and day.
