Description
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.

T56 trans fluid I WOULD LIKE TO KNOW WHAT TYPE OF TRANS FLUID DOES THE T56 USE.I HAD A T45 AND USED THE ROYAL PURPLE SYNCHROMAX WITH GOOD RESULTS. NOW I HAVE A T56 AND HAVE BEEN TOLD TOO MANY DIFFERENT VEIWS ON WHAT TO USE

WILLEG89

  • The T56 service manual recommends Dexron lll fluid. You can use Royal Purple syncromax or GM syncromesh type fluid also.

Would this fix...? I'm long over due for a transmission fluid change and most likely going to buy this fluid, but I was wondering if this would fix a noise I have in 5th gear, (rubbing noise that is not constant but more of a lopping pattern noise) Keep up the awesome service AM!

MiniHorse

  • This fluid will quiet down transmission noise to a degree. It really all depends on what's causing the noise. As long as it's not like a bad synchro or something to that effect it should help.

Do you have to have a new transmission or stang to swith to the royal purple? I would like to swith the transmission fluid in my 2002 mustang. My tranny shifts hard and would like to try new fluid.

bamfrtech

  • No, you can use Royal Purple without issue. I run it in my 3650 and have for years. Make sure you get the right fluid for your type of transmission and the right amount. IF you don't have a manual, buy a Haynes or Chiltons to determine capacity.

    Shifts like hot butter

    I put some of this in at 70k it was definitely an improvement but it was also the first transmission fluid change. The improvement was noticeable but I can't say that it was from the royal purple and not from it just being fresh tranny fluid. I have a hurst shifter and with this fluid you can feel every single movement in the shift. I love it that way. I feel more connected like I know how the car is behaving. I would recommend this to anyone else.

    Smooth Operation

    I have the new China made 6speed in my 2011 mustang and I tell you what it was very stiff going into gears cold and hot. This product helped out a lot. I would recommend this to anyone wanting to smooth out there transmission and also add better protection.

    TR3650 Second Gear Hitch

    I have a 08 GT, with pretty much every bolt on there is, bought it new, and it has always had a hitch (a little difficult) going into second. Just changed to RP Synchromax, and what a difference, this oil really made a difference. Hitch completely gone, yes, gone, and all other gears are smooth as silk. I have to tell you, if you haven't changed you Tranny oil, you are really missing out on a quality upgrade. Banging second gear with confidence now, and yes, it has had the Tri-Ax since almost new. Worth every penny boys and girls.

    Smooth

    Made shifting smoother overall and improved but did not really any performance gain. Had to put in a little more than 3.2 quarts in order for it to be full. I just bought a pump with two pipes that sucks in from one pipe and comes out for the other pipe that way I put one in the fluid bottle and one in the fill plug and kept pumping in.

    Awesome Lubricant

    This stuff is fantastic! I just put 3.2 QTS of it in my TR3650 and the notchiness has virtually gone away. Not only that, but AM has the best price around; a full $6.00/QT less than my local Pep Boys! AM and RP rock!

    great oil

    works great . the easiest way to refill your trans is to fill a suction gun up with royal purple trans fluid then push the oil out of the suction gun. into the fill hole . and always use rtv thread sealer on drain plug and fill plug thrads to insure no leaks.
