In a joint effort with Allison Transmission, Shell Lubricants offers Shell Spirax S6 ATF A295 synthetic automatic transmission fluid to extend drain intervals. Shell Spirax S6 ATF A295 lasts up to 300,000 mi (483,000 km) under normal conditions or 150,000 mi (241,000 km) under severe conditions without risk to the transmission components or warranty. The fluid protects automatic transmissions from wear, pitting, and corrosion, reducing service and maintenance costs. Additional features include resistance to viscosity and thermal breakdown for longer oil life; improved friction characteristics and friction retention; and low-temperature capability.
