Purpose and Specifications
Shell Spirax S1 ATF TASA is a premium transmission oil designed for automatic transmissions, power steering, and hydraulic systems in heavy-duty off-road vehicles. This 20-liter pail (EAN 5011987188471) meets GM Type A Suffix A specs, delivering smooth shifting and long-lasting protection in tough conditions.
It excels in extreme temperatures from -30°C to 150°C, keeping fluid thick for hot hauls and flowing easy in cold starts. Built-in cleaners keep gears free of sludge, while anti-wear additives shield parts from grinding during heavy loads.
- Smooth, reliable shifts every time, no slipping or harsh jerks.
- Stays tough against heat and oxidation for fewer breakdowns.
- Perfect for trucks, loaders, and off-road machinery.
When to Use / Replace?
Use Shell Spirax S1 ATF TASA in older GM vehicles or heavy equipment calling for Type A Suffix A fluid. Ideal for off-road work where dirt and heat push transmissions hard.
Replace every 40,000-60,000 km or 24 months under severe duty like towing or dusty trails. Check fluid level monthly; top up if low. Shelf life is 5 years sealed in cool, dry storage.
FAQ
Is this safe for my power steering? Yes, it protects pumps and racks in heavy-duty setups, preventing leaks and stiff steering.
Can I mix it with other ATF? Best to flush fully first; mixing may cut performance in older Type A systems.
What if I run it too long? Dirty fluid causes slipping gears and overheating—swap at 50,000 km max for off-road use.
