Product Highlights View Full Description

AMSOIL Signature Series Multi-Vehicle Synthetic ATF is engineered to outperform conventional automatic transmission fluids and exceed the performance requirements of most North American, European and Asian vehicles. This sophisticated formulation provides outstanding performance and protection in the severe operating conditions of today’s most advanced transmission designs.

Bulletin From Filter Manufacturers Council (16k PDF)

Transmissions in commercial vehicles, SUVs, trucks and vans – particularly those used for hauling or towing – are subjected to severe-service operation and increased heat. Elevated temperatures cause fluids to break down, allowing damaging metal-to-metal contact and the formation of sludge and deposits. The problem is worse in modern transmissions with more gears, clutch packs and narrow oil passages that require clean, high-quality fluid to achieve maximum performance and life.

AMSOIL Signature Series Synthetic Automatic Transmission Fluid is specifically formulated to withstand the rigors of heavy towing, elevated temperatures and challenging terrain. It remains fluid in sub-zero temperatures and provides reserve protection during heavy use and even abuse.

AMSOIL Tech Tip: Transmission Fluid


Proven in 180,000-mile, Severe-Service Taxi Fleet Field Trial
To demonstrate its effectiveness in severe service, Signature Series Multi-Vehicle Synthetic ATF was installed in Las Vegas taxi cabs. The vehicles routinely encountered demanding stop-and-go driving loaded with passengers and cargo, while the desert environment presented extremely hot ambient temperatures, placing enormous strain on the fluid. Following 180,000 miles, a transmission was selected for analysis. The Aluminum Beaker Oxidation Test (ABOT) is an industry standardized test used to determine a transmission fluid's oxidation resistance, which is a good indicator of its service life. Testing by an independent, third-party lab revealed that after 180,000 miles in severe service, Signature Series Multi-Vehicle Synthetic ATF resisted oxidation longer than required for new fluid to meet the Chrysler ATF+4 specification (see graph). Internal components, including the valve body and clutch plates (pictured), were virtually free of damaging sludge, deposits and wear, confirming the lubricant's high level of protection for severe-service applications.

Reserve Protection Against Heat After 180,000 Miles

Protection against heat

Clutch Plates

Protects Against Thermal Breakdown
Signature Series Synthetic ATF is formulated with high concentrations of antioxidants, making it naturally heat resistant. It provides outstanding protection against sludge and varnish deposits that clog narrow oil passages and contribute to clutch glazing. After 180,000 miles in severe service, fluid analysis revealed Signature Series Multi-Vehicle Synthetic ATF contained 83 percent of its original oxidation inhibitors, proving its long-lasting resistance to thermal breakdown.

Outstanding Wear Protection
Varying speeds and loads causes torque multiplication and extreme stress on gears and bearings. AMSOIL formulated Signature Series Synthetic ATF with high film strength and premium anti-wear/extreme-pressure additives to help prevent wear during severe service. In the industry-standard FZG Gear Wear Test, Signature Series Multi-Vehicle Synthetic ATF that had been used for 180,000 severe-service miles achieved a “Pass” at stage 12 – the highest stage. The results exceeded the Ford MERCON V and Chrysler ATF+4 specifications for new fluid, demonstrating the lubricant's long-lasting wear protection.

Cold-Temperature Fluidity
Cold, thick automatic transmission fluid lengthens shift times and reduces fuel economy. Signature Series Synthetic ATF is wax-free and delivers extraordinary cold-flow properties. It helps improve shift response, energy efficiency and warm-up times.

Friction Durability
Today's transmissions are smaller and must withstand higher horsepower and torque while delivering smoother shifts, all with longer fluid life recommendations. AMSOIL Signature Series Synthetic ATF is formulated with friction modifier additives that deliver outstanding clutch-holding capacity (static friction), torque-transfer ability (dynamic friction) and anti-shudder properties (slipping torque-converter clutches). Analysis reveals that after 180,000 miles in severe service, Signature Series Multi-Vehicle Synthetic ATF provides nearly identical friction properties as new fluid for smooth, reliable shifts.

I drive a 2002 Honda Odyssey. This is a heavy van that's actually classed as a light truck. However, it has only a car-type transmission. My mechanic recommended that I switch to Amsoil Multi-Vehicle ATF which would better tolerate the high heat in this hard-working transmission. He also recounted knowledge of premature failures in transmissions similar to mine.

I switched to Amsoil ATF at 127,000 km (79,000 miles). I immediately noticed that the shifts were crisper and quicker. I now have 226,000 km (140,000 miles) on my van. The transmission continues to work like new. It has never needed any repair. The ATF always looks fresh: bright pink color and sweet smell.

I recommend AMSOIL ATF for its excellent service even in demanding applications.

ATF Fluid Review and Amsoil Inquiry

I've never had any issues with Amsoil products and I've used them for a long time, nor have I had any issues with this Amsoil ATF fluid. Can Amsoil inform their customers of what constitutes synthetic oil to be considered "Full Synthetic." I was informed by the GoPure Power Company that processes oils and makes billet oil filters that manufacturers who make synthetic oil are only required to have 24% additives in the mix for an oil to be considered "Full Synthetic." That's very illuminating to know. If this is true, then synthetic oil companies save about 70 cents on each quart but double the price of the oil. There's probably a reason this information is kept from the consumer public. The Pennzoil vs Castro and AV1 court cases of the 90's shed some light on this. Anyway, I'll probably switch to a mineral oil in the future.

Comments about Signature Series Fuel-Efficient Synthetic Automatic Transmission Fluid:

seems to use less fuel, sorry no data.
But when driving normally I'm going +10 km faster, so to me better than the Amsoil OE

"AMSOIL Signature Series Fuel-Efficient Synthetic ATF is backward compatible and replaces DEXRON III fluids in older"
put into a '97 Dakota, most likely the last time i have to do it.. 184 K killo-meters.
As rust is starting to be a problem. And fuel prices going up..

Best ATF

By 

from Hudson Valley

Verified Buyer

Comments about Signature Series Fuel-Efficient Synthetic Automatic Transmission Fluid:

Bought Signature Series ATF to replace the OEM fluid in my Honda Odyssey that has 25,000 miles. After just one drain and fill that replaced about 40% of the capacity, the transmission shifted MUCH more smoothly. After a second drain and fill a week later, the amount of new fluid is almost 75%. The tranny is now silky smooth. This is the BEST ATF by far.

Good Buy

Comments about Signature Series Multi-Vehicle Synthetic Automatic Transmission Fluid:

I put in a bypass oil filter on the flagship Mercedes and used Amsoil oil, and every year I had it tested and they said, oil is good. Finally after 8 years I just decided to change the oil even though the lab kept saying it was good, and it was still transparent when I drained it. That says a lot about a perfect filter and a perfect oil in a great big engine.

Comments about Signature Series Multi-Vehicle Synthetic Automatic Transmission Fluid:

This stuff is great! So far, I have used it in a Dodge that requires ATF+4 (165k miles), a Ford motorhome that requires MERCON (42k miles), a Jeep that requires DEXRON (186k miles), and a Honda that requires DW-1 (169k miles). It was originally installed in all the vehicles over 10 years ago, and after all that time they are still going strong. I have done nothing to the transmissions except for periodic fluid changes. The fluid stays red and shift quality is great.
