Worked fine . **Q: I will be replacing the Pensoil Syncromesh in my Jeep Wrangler with the NV3550. Will this be safe to use?** A: I don't have a Jeep, but the Royal Purple Synchromax fluid is specifically designed to replace all Synchromesh applications so as long as your Jeep's NV3550 calls for Synchromesh (which I think it does) then you should be fine. Synchromax would be a good upgrade. **Q: Anybody try this in sonic with a 1.8 5 speed? Thanks** A: I'm sure the trans in a sonic is Korean made and I use it in my Honda civic si and it made my shifts smooth and precise **Q: Will this work in a 2014 mustang manual?** A: There is a tool on the Royal Purple website: you enter your make and model (and year) and it shows you all the recommended products for your car (engine, transmission, transfer case, differentials, etc.) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by V***R on 20 December 2023* ottimo ### ⭐⭐⭐⭐⭐ Review *by A***E on 16 June 2025* Super huile pour boîte ### ⭐⭐⭐ Review *by C***S on 10 January 2023* No he notado ninguna diferencia ni mejoría respecto al aceite de transmisión de la marca Honda. Esto quiere decir que es un producto caro para lo que ofrece. Probé un producto de una reconocida marca alemana y he notado una diferencia importante, las marchas entran mas suaves y no me cuesta meter la marcha atrás. Mi conclusión es que es un producto caro para lo que ofrece. El aceite de transmisión de la marca alemana es a mitad de precio y me va mucho mejor. ## Frequently Bought Together - Royal Purple-ROY01512 ROYAL PURPLE SYNCHROMAX QT.
