AMSOIL Signature Series Fuel-Efficient Synthetic ATF

AMSOIL Signature Series Fuel-Efficient Synthetic ATF will soon meet the GM Dexron HP specification.

AMSOIL has reformulated their Signature Series Fuel-Efficient Synthetic ATF to meet the General Motors Dexron HP specification. The new Dexron HP formulation will become available once the previous formula has sold off. The new Dexron HP formula is projected to be on sale some time in May 2016. AMSOIL Signature Series Fuel-Efficient Synthetic ATF will be a high-quality replacement for AC Delco Dexron HP Automatic Transmission Fluid.

About The Dexron HP ATF Specification

The “high-performance” Dexron HP automatic transmission fluid specification for is for Chevrolet, GMC and Cadillac applications equipped with the Hydra-Matic 8L90 eight-speed automatic transmission. The Dexron HP spec has characteristics such as a full synthetic make-up, low viscosity for optimized fuel economy, enhanced resistance to foaming and long service life.

The factory-fill product for the 8L90 is AC Delco Dexron HP Automatic Transmission Fluid which is sold at Chevrolet, Cadillac and GMC dealerships. A US quart bottle of AC Delco Dexron HP retails for between $20.00 and $25.00 in the United States and upwards of $42.55 in Canadian. We can sell the AMSOIL Signature Series Fuel-Efficient Synthetic ATF for a fraction of these prices. Contact us using the form on this page for more information.

About The GM 8L90 8-Speed Transmission

As the industry is trending rapidly toward 8-speed (and larger) transmissions, GM designed and built the 8-speed Hydra-Matic 8L90 automatic transmission for the 2015 model year. The two main attributes of this transmission are improved fuel economy and increased torque tolerance. This state-of-the-art transmission is found in conjunction with the “LT1”, “LT4” and “L86” 6.2-litre engines in the following GM applications.

  • Cadillac Escalade/Escalade ESV (2015 and newer)
  • Cadillac ATS-V (2016 and newer)
  • Cadillac CTS-V (2016 and newer)
  • Cadillac CT6 (2016 and newer)
  • Chevrolet Camaro (2016 and newer)
  • Chevrolet Corvette Z06/Z51 (2015 and newer)
  • Chevrolet Silverado (2015 and newer)
  • GMC Sierra (2015 and newer)
  • GMC Yukon Denali/Denali XL (2015 and newer)

Like several other modern transmissions, the Hydra-Matic 8L90 eight-speed automatic does not have a top-fill plug or dipstick. Fluid can only be added through a plug on the lower side of the unit. We disagree with this trend as it is a barrier to do-it-yourself motorists who perform their own fluid checks.

If you have a Ram 1500 pick-up with the ZF-8HP 8-speed transmission and are thinking of taking your truck into your Dodge dealer for a transmission oil flush, here is an analysis of the costs of this procedure. We hope you are sitting down.

ZF 8HP 8-Speed Transmission

A few months ago, we ran an article about the outlandish cost of an EcoDiesel engine oil change at Dodge dealerships. But we recently started hearing rumblings about the cost of an ATF flush for Ram 1500 trucks with ZF 8-speed automatic transmissions. So we called a few Dodge dealerships in Canada and the United States to verify. As we learned more about the cost of the ATF change, the price of the motor oil change seemed like a wonderful value!

Ram EcoDiesel Transmission Oil Change Cost

We called a few random Dodge dealers and asked for quotes on a complete ATF oil change for a 2015 Dodge Ram 1500 with the 3.0L EcoDiesel engine. The prices below are for a complete ATF change, replacement oil pan and labor. As you can see, there is a fairly wide range in prices, so the parts and procedure costs may vary at your Dodge dealership.

  • USA $824.00 to $1105.00 (before taxes)
  • Canada $1135.00 to $1490.00 (before taxes)

The German-made ZF-8HP75 8-speed transmission is found in several Ram models as well as some Dodge Charger, Challenger, Durango and Jeep Grand Cherokee models. This versatile transmission is even found in some Roll-Royce, Aston Martin, Range Rover and Maserati models.

What Makes This ATF Oil Change So Costly?

The main items billed for this ATF service are 9 (or so) quarts of the Mopar ZF 8&9 Speed ATF, a replacement oil pan (which has an integrated oil filter) and one or two hours of labor. The ATF and transmission pan are priced to the moon, so this is where the bill really skyrockets. The replacement cost of a complete ZF 8-speed transmission is $4000 USD which is relatively modest when one considers to the absurdity of a $1000-plus fluid change.

Note that as these ZF 8-speed transmissions are relatively new in Dodge applications, very few Dodge dealers have actually performed an oil change on them. More often than not, service advisors will offer their “$159.00 ATF Flush Special” when you request an ATF change for these trucks. Once you ask them to check on the cost of the ZF 8&9 Speed oil and the pan/filter, they quickly learn that this is no ordinary ATF flush.

Price of Mopar ZF 8&9 Speed ATF

  • USA- $43.25 to $48.87 per quart (946ml)
  • Canada- $58.40 to $70.00 per quart (946ml)

Your eyes aren’t deceiving you; Mopar ZF 8&9 Speed ATF costs almost $50 per quart in the US and upwards of $70 per quart in Canada. For a complete fluid change, 9 quarts will be required and possibly one or two extra for the flushing proposes. Why is this ATF so expensive? Who knows? There are top-flight full synthetic substitutes (we offer a suggestion below) that meet the ZF 8&9-Speed spec and are available for a fraction of what Dodge dealers charge for this oil.

Mopar ZF 8&9 Speed ATF is a full synthetic oil made by Shell and is also marketed as ZF Lifeguard 8. The industry spec for this oil is Shell “M-L12108”. Shell designed and manufactures this ATF for the OEM’s but does not market an M-L12108 compatible fluid under the Shell brand. This fluid has a low viscosity to minimize friction for maximum fuel economy. The factory-fill ZF fluid has a translucent, slightly green appearance with an additive that helps technicians detect leaks under UV light.

Price Of Mopar ZF Oil Pan (Part # 68225344AA)

  • USA- $335.00 To $378.55
  • Canada- $453.00 to $522.00

The Mopar 68225344AA oil pan for ZF transmissions is a plastic unit with a non-removable, non-serviceable oil filter molded into it. Therefore, the pan has to be replaced when a complete oil change service is performed. The filter itself has a synthetic media, while the pan also has strategically placed magnets to gather metal filings. Also included with this kit is a gasket, replacement pan bolts and a replacement oil fill plug. While this plastic oil pan is reasonably well-designed, its finest attribute is its ability to completely empty your wallet.

About The ZF-8HP75 8-Speed Transmission

The ZF 8HP transmission series was introduced in 2008 to great fanfare and has proven to be durable, efficient and a great performer in a very wide variety of applications. The reason that the industry is moving toward 8-speed transmissions (and more gears in some cases) is to improve fuel efficiency. With 8-speeds, the engine can always be in an optimum RPM range. ZF 8HP transmission gear shifts take place in milliseconds and can shift from 8th gear directly to 2nd when the situation warrants.

These transmissions do not have a dipstick or top fill port of any sort. Oil is added through a plug on the lower side of the transmission housing. There is much confusion at Dodge dealerships about the proper ATF change interval for these ZF transmissions. On one hand, they are actually marketed as “fill for life” implying that the oil never needs to be changed or checked unless there is a problem. On the other hand, there is a severe service fluid change interval set at 60,000 miles (100,000 kilometres).

Elite ZF 8&9 Speed ATF Replacements

We offer two synthetic automatic transmission fluids which cover the Shell M-L12108 specification for ZF 8&9 speed transmissions. The premium option is the AMSOIL Signature Series Fuel-Efficient Synthetic ATF. This elite ATF is designed for long drain intervals and protects during temperature extremes. We often refer to a tortuous field test AMSOIL conducted using AMSOIL Signature Series Multi-Vehicle Synthetic ATF (the sister product of Signature Series Fuel-Efficient Synthetic ATF) in Las Vegas taxi cabs over 100,000 miles. Signature Series Synthetic ATF is as tough as they make them.

The other AMSOIL product that covers the Shell M-L12108 spec is AMSOIL Signature Series OE Synthetic ATF. This is AMSOIL’s budget-priced synthetic ATF and is designed for OEM drain intervals. As transmission fluid changes are a relatively rare procedure, we would spring the few extra bucks for the ultra-premium Signature Series Fuel-Efficient Synthetic ATF.
