    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.

      So smooth

      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.

      Sooner than needed but smoother now

      I bought 4 bottles of this. Although the Haynes manual and says the MT82 in the 2012 GT only needs 2.7 litres (3 bottles) I thought it was best to have more than needed. Turns out the extra bottle was needed as the transfer pump couldn't pick up all of the fluid in the reservoir. Before I changed the fluid the Ford Racing short shift was precise, but a little notchy, and occasionally baulked on 2nd to 3rd shifts. Post fluid change, the shifts have been much slicker while retaining the precision.

      The best stuff out there! Beats OEM!

      Changed my 2012 V6 Mustang manual trasnmission with this. The OEM stuff was installed not long prior based on the color of what came out... and I noticed a big difference. Shifts like butter... and it's harder to lug on the engine if I shift too soon. It just grabs and goes. AM had the best price around free shipping on three. Hard to beat!
