Below is a partial copy of the text on Mobil's website product description for Mobil Multi-Vehicle ATF:
Product Description
Mobil ATF 3309 is an exceptionally high performance lubricant that meets original equipment manufacturers' specifications for use in certain slip-controlled lock-up automatic transmissions. Mobil ATF 3309 is recommended for use in transmissions made by Aisin-Warner requiring a fluid approved against Type T-IV, JWS 3309, GM 9986195 and VW/Audi G-055-025-A2. These Aisin-Warner transmissions are used in CERTAIN domestic and foreign vehicles, including Toyota, Lexus, Audi, Saturn, Ford, Volvo, Volkswagen, Saab, Porsche and Mitsubishi.
Features and Benefits
The unique formulation of Mobil ATF 3309 is designed to provide excellent lubrication of transmissions in specified Aisin-Warner slip-controlled lock-up automatic transmissions. These outstanding performance capabilities translate into significant operational benefits, including:
- Excellent lubricating characteristics for quiet operation and smooth shifting in approved transmissions
- Controlled friction properties for smooth and efficient transmission of power across all normal temperature ranges
- Helps to control transmission shudder and provide excellent vehicle driveability
- Helps to extend transmission life based on excellent wear control
- Long fluid life based on excellent oxidation resistance
- Excellent viscosity stability (high viscosity index) to help assure adequate lubrication without excessive thinning in severe high-temperature service or thickening at low starting temperatures
- Resistance to foaming
- Superb protection against rusting and corrosion
- Compatibility with synthetic rubber seal materials
Applications
Mobil ATF 3309 is recommended for use in transmissions made by Aisin-Warner requiring fluids approved against JWS 3309 or GM 9986195. It is also recommended for service fill applications where Toyota T-IV, T4, T-III or T3 are called for. Please refer to the owners' manual for proper fluid requirements.
I visited a Dodge dealer this afternoon and the parts man brought out a bottle of MOPAR Aisin ATF. On the back of the bottle the phrase above from the Mobil Multi-Vehicle ATF description appears word for word. Here it is:
"Approved for use in transmissions made by Aisin-Warner requiring fluids approved against JWS 3309"
The JWS 3309 appears to be the key specification.
The "JWS 3309" spec also appears on a bottle of Mobil Multiple-Vehicle ATF purchased this afternoon from an Autozone.
I am certain that Mobil Multi-Vehicle ATF is repackaged for Chrysler as Aisin ATF. The parts man at the Dodge dealer told me the price was $10. 50/quart. I paid $7. 49/quart at Autozone, a significant savings.
Sag2 was correct. The proper ATF for use in Aisin six speed automatic transmissions installed in Dodge Ram C&C trucks is NOT ATF-4 as I wrote last night.
I was thinking initially that this Mobil Multi-Vehicle ATF is a high quality but generic ATF for many brands of auto makers but now that I think about it, maybe all the vehicles on the approved list for this fluid are using Aisin tranmissions. Maybe "ATF" in this case means "Aisin transmission fluid" not automatic transmission fluid.
