Royal Purple Synchromax Manual Transmission Fluid

4.74 out of 5 stars 80 Customer Reviews

Royal Purple Synchromax manual transmission fluid is recommended for manual transmissions that specify an automatic transmission fluid or motor oil. It is also ideal for 4x4 transfer cases and/or 2-cycle motorcycle gear boxes. 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. It is fully compatible with all types of friction materials, and offers excellent oxidation and corrosion protection, without affecting the soft metals commonly found in manual transmission synchronizers.
