    Unrivaled Protection. Royal Purple Synchromax® is a full synthetic transmission fluid that provides superior wear protection for your Wrangler'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 Jeep's next fluid change for the cheapest insurance you can get against future transmission breakdowns.

    Smoother 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 Wrangler 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 on 1987-2020 Jeep Wranglers that specify an automatic transmission fluid or motor oil and is also suitable for transfer case use.

            Spend the money now

            We all know royal purple is not the cheapest but you get what you pay for. Worth every penny to keep your tranny shifting right.

            Royal purple refill

            Just got an 05 TJ. I changed the fluid hoping it would shift better. It made a tiny bit of difference but I guess it's just the nature of the beast!

            Best for NSG370

            I have tried all of the fluids in my 6 speed and this is the truly the best one. Everyone was saying Red Line was good and it turned out to be total trash along with Amsoil, Pennzoil and of course Mopar fluid. The NSG370 is finicky from 1st to 2nd in cold weather regardless of the fluid but overall, this fluid shifts the smoothest over all other options.

            The difference

            I filled my tranny up with water. So I ran some cheap motor oil through it then this. It’s all back to normal now and probably even better than normal tbh!!

            Royal purple

            Great product, keeps your ride working smooth. Installed in 2005 TJ with 6 speed manual.

            extremely good

            everyone says that this is good stuff and I believe it shifting is so smooth that I can`t even explain It.

            Best you can get!

            Great for your transmission and differentials. Dyno proven to reduce friction and transfer more torque.

            Trans Lube

            It lubes ..... not better than what was originally in the Transmission. Actually , first thing in the morning it is really difficult to shift . A couple of blocks down the road it gets much better.

            great product

            as I replaced the existing fluid in my 04 TJ it seemed to quiet the Differential and trans. noise.

            Better than factory

            Takes about 3 qts, so buy 4 for a top off. First and second gear were getting crunchy, and this smoothed them back out. I use in the desert, so I can't say how well it works in the cold. Perfect for running in the heat.
