If you have a manual transmission in your 1979 and newer Mustang, and are looking to promote smoother shifting and better wear protection, then you should check out a quart or two of the Royal Purple Synchromax manual transmission fluid. Now, this extremely popular and highly rated fluid here on the site will work with any manual transmission in your Mustang, but is not advised for automatic transmissions or rear ends. Your price point per quart will be around 15 bucks, while the install will vary depending on your car, but let's call it one out of three wrenches on the difficulty meter, with a little bit more on that topic later in the video. So, T5, T45, 3650, 6060, T56 or MT82, it doesn't matter, the Royal Purple Synchromax we are talking about here today will be for you. Now, the Synchromax is a synthetic transmission fluid which is designed to improve shifting and reduce gear noise through Royal Purple's proprietary Synerlec technology. And this is one of those products where, guys, I really encourage you to check out or read up on some of the 100 plus, 5 star reviews on the site, because, listen, I can sit here and tell you what's in this stuff all day long and why it's so great, but it's always better to hear from different Mustang owners out there who've actually filled their transmission up with this stuff and it gets them real-world feedback. But either way let's get back to the Synchromax here. And aside from the smoother and quieter operation, Royal Purple also states that their additives in this Synchromax will help protect some of the softer metals typically found in manual transmissions, and more specifically, their synchronizers. Also worth noting is that cold weather owners might be drawn to this fluid a little bit better because of the lower operating temperature, which will help eliminate some of that notchiness on some of the colder mornings. Now, the amount of fluid needed will differ from trans to trans, but you're gonna be looking at three to four quarts here depending on your setup, and for that I would recommend to check out your owner's manual at the end of the day as it does differ a bit to bit from transmission. Now, as far as additives are concerned, well, that's another area that will differ from setup to setup. And I will say, most cars will be fine just using the fluid itself here, but again, check your manual, see if one is needed just to be on the safe side. Now, filling the trans can be done a few different ways, but I will say that using some sort of pump, whether it be vacuum or handheld, will certainly make your life easier compared to just dumping it in using some crazy long funnel. Either way, guys, let's call it one out of three wrenches on the difficulty meter here, and about 30 minutes to an hour of your time to get the old fluid drained and the new fluid in place in your transmission. So, wrapping up this short and sweet video, if you're looking for a very popular fluid to fill the manual transmission in your '79 and newer Mustang, then check out a few quarts of the old Synchromax here from Royal Purple, right here at americanmuscle.com.

not good for mt82 trans
listen the oil does every thing they say had it 2 years i track my car and this oil foams up and clogs the trans breather valve when it drys then you get trans leak pretty bad this was diagnosed through ford performance as the dealer could not figure it out. use the recommended product and change more often or possibly go to red line (if the additive packs dont foam up. mine was still under warranty I got lucky dont make the same mistake with the mt82 my gt is 2016 with 20 k and 18 track daysHelpful (1)

Well, it does what they say!
noticed the the MT 82 trans on the Mustang GT is a little noisy and this is on my car with 1700 miles on it. So took a chance and changed out the fluid with the Royal Purple product. Have to say it does run smoother on shifts and at low speed around the neighborhood is quieter. Turned on the quiet exhaust mode to really listen and yep less whine. For those of you thinking about doing the change of fluid, I did a setup that might make it easier to fill then the lame 1oz pumps on the floor. Just get a piece of clear tubing about 5 foot. Take one end and put it in the fill hole take the tubing and zip tie it to the exhaust( yes it has to be cool, duh) this will anchor the hose into the fill hole. The other end jam on the bottle tip after nipping off the tip and just invert the bottle and hold up at your side. Gonna need to pop a hole in the base of the bottle once inverted to allow air to fill and let the fluid out. all said and done it took less then 20 mins to drain and fill.Helpful (0)

Ease of mind
13 Gt VMP gen 2R 50k ,miles Replaced the oem trans fluid with the royal purple due to reviews / reputation. Was easy to access with allen wrench / fluid pump. Wouldn't recommend trying it with out some sort of pump due to the tightness of the fill location. Overall feels smoother than before at low - mild rpms, Mid to higher rpm on occasion have clunky feel. SatisfiedHelpful (1)

Royal purple synchromax
Replaced the clutch and pressure plate so while the transmission was out did a fluid change. The new royal purple I can actually notice the difference with less heat from the transmission and the shifts feel smoother will highly recommend this product.Helpful (0)

Hello...car nooby here...so I NEED a manual transmission oil change in my 2006 S197 GT, but I need to know how much of this do I need for a full top off after I drain it and how to fill it...can I fill it from the shifter and unscrew the knob and poor it in? or Do I have to fill it from the fill hole?
The 2006 Mustang GT equipped with a manual transmission will require 3.25 quarts of transmission fluid. After you drain your transmission, you will need to refill it from the fill hole located on the transmission.
how many quarts of transmission fluid do i need for my 1998 t-5 transmission?
you need 3 quarts. you can refer to your owners manual.
How many quarts for the t 45 in my 99 cobra?
The T-45/T-3650 transmission will take approximately 3.25 quarts to fill the transmission after a full transmission fluid flush.
Would it be okay to mix this product with Slick 50 manual transmission formula? 1 bottle = 10 oz dose.
We do not recommend mixing additives with the Royal Purple Synchromax Manual Transmission Fluid.
Yes this is safe to use. My local Ford dealer assured me it is great for performance enthusiasts.
Three bottles will be required to fill your transmission.
Hello, FranklinNT5U3728822 the manual ecoboost uses 2.7 Qts
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.
This will help with smoother shift points and you will need 2.7 quarts for your car.
You'll need 3.25 quarts for the 5.0L Manual.
After a full transmission fluid flush, it is recommended to fill back up with approximately 3.25 quarts.
