Royal Purple Max ATF Automatic Transmission Fluids are a synthetic, high performance, longlife, multipurpose, automatic transmission fluid.  High performance lubricant manufacturer Royal Purple has re-formulated its Max ATF® automatic transmission fluid to meet the specifications of wider range of transmissions. Max ATF® is a long-life transmission fluid that’s proven to improve performance. It’s been recognized for its ability to significantly reduce friction, so a vehicle can send more power to the ground. It’s also been proven to reduce operating temperature for longer transmission life. Royal Purple Synchromax is recommended for manual transmissions that specify an automatic transmission fluid or motor oil.  It is also ideal for transfer cases and 2-cycle motorcycle gear boxes.  Synchromax is formulated with Royal Purples synthetic, proprietary Synerlec additive technology, which offers improved shift quality over a wide temperature range and reduced gear noise.  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.
