Synchromax is a synthetic manual transmission fluid designed to increase performance and expand the life of your manual transmission. Using Synchromax improves shifting, reduces gear noise and increases power transfer to the wheels. As a performance transmission fluid, it also lowers operating temperatures and provides outstanding wear protection.

Synchromax is recommended for manual transmissions that specify an automatic transmission fluid. It’s also ideal for 4×4 transfer cases and motorcycle gear boxes. Fully compatible with all types of friction materials, Synchromax provides excellent corrosion and oxidation protection without affecting the soft metals commonly found in manual transmission synchronizers.

Formulated with Royal Purple’s proprietary Synerlec® technology, Synchromax is the top synthetic transmission fluid for protection and an all-around smoother ride.

Replacing or rebuilding your transmission can cost thousands. Avoid costly transmission repairs by replacing old fluid with Synchromax. Are you ready to outperform?
