Is there a specific aftermarket atf that is recommended for this application, or will most any multi-vehicle type atf work?
Having been in contact with all the ATF suppliers in Australia (some more helpful than others) in regard for a safe to use ATF for 2017 Elantra auto. I have concluded in my opinion RAVENOL ATF SP-IV Fluid is the best bet, costing $26 less per litre than the overpriced OEM fluid. Here is some information from Ravenol on two ATF fluids. N0TE THE INFORMATION ON MULTI VEHICLE ATF. Hope this is helpful for Australians viewing this site.
Application Notes
RAVENOL ATF SP-IV Fluid is recommended for all vehicles with Hyundai 6-stroke automatic transmission
A6LF1/2/3, A6GF1, A6MF1/2 from 2009.
RAVENOL special transmission fluid is special development for special gear and cannot be selected on
the basis of technical parameters (viscosity, etc.). Therefore the decision was made not to give technical
data. Please note: RAVENOL special transmission fluid is exclusively to apply under the original number,
as indicated in the product information. Not sure of the correct transmission fluid, you can ask your
garage or the car dealer with respect to the original OEM gear type and number or consult our advisers.
It must be specified the VIN code (Vehicle Identification Number) of your vehicle. Misapplication of
RAVENOL special transmission fluid can lead to malfunction of the transmission shifting problems,
increased fuel consumption, unwanted slip behavior, etc. cause and cause the failure of the
transmission. Ravensberger Schmierstoffvertrieb GmbH does not liable for transmission failures in case
of wrong selection of RAVENOL special transmission fluid.
RAVENOL Multi ATF LVS Fluid is a product with very wide manufacturer coverage and can be used in almost all conventional automatic transmissions with shift groups.
Not suitable for CVT automatic transmissions.
RAVENOL Multi ATF LVS Fluid can be used as refill oil in a wide range of applications to meet the requirements of Ford, GM, Toyota, Honda, Nissan, Hyundai, KIA, BMW, Mercedes, Volvo, VW, Audi and others. It will be used if no suitable original oil or RAVENOL Professional Line oil is available. Observe the manufacturer's instructions.
Multi ATFs generally only meet the required specifications, i.e. the minimum technical requirements for an ATF. For that reason they are not suitable for permanent use. Multi ATFs should therefore only be used as a temporary replacement or for refilling if the special gear oil is not available for your application.
For continuous operation we recommend the use of our
RAVENOL ATF Professional Line gear oils. These special oils are optimally formulated for individual automatic transmissions. They exceed the minimum requirements / specifications.
