STF protects gears, bearings and internal clutches in extreme heat environments. By reducing friction, heat and wear, it improves shifting characteristics and lowers operating temperatures. Exceeds performance requirements for GM, Chrysler, Honda and MINI Cooper synchronised transmissions. STF features advanced synthetic base stocks, multi-functional performance additives, corrosion inhibitors and a foam suppressor to provide excellent synchroniser performance and compatibility with yellow metals found in manual transaxles and transmissions.

Recommended for manual transmissions that specify automatic transmission fluid as a factory fill.
