Aftermarket ATF

[dan765]

Thoughts on using an aftermarket ATF in the 8-speed transmission? I know Valvoline makes an ATF that lists the SP-IV-RR as a spec....

Just curious here. Is the thought that the aftermarket will be better, or is it cheaper?

I don't know, but I have always thought that fluids that claim to meet multiple specs, probably don't match any single one of them perfectly.

Cheaper. However, I've used aftermarket in other vehicles without a problem. But in the 8-speed on my '12 Genny, can I do aftermarket or should I bite the bullet and get the genuine ATF?

How many quarts are you planning on getting? For a drain/fill, you won't need more than 5qts. OEM fluid is currently $11.41/qt:

00232-19052 - Genuine Hyundai ATF SP-IV-REAR

Valvoline is ~ $8/qt. If you buy a box of 6, that's ~ $48. If you buy 5qts of OEM, that's ~ $57 (I'm pretty sure your local dealership would be willing to price match the link above).

*IMHO, you won't hurt anything by going with Valvoline.

But, for ~ $9 more, you're putting in OEM fluid.

I use oem fluid. As princleybug said its a only a couple more bucks. I would say valvoline would work. But why chance it. Dealer just did my 15 5.0. I can definitely feel a difference. Smoother shifts. I have 35k on my and the service guy said it dont need to be done. I say cheap insurance!

I'm no expert, but nowadays transmissions are so high tech that I would ONLY use OEM for it, even if it costs $40/qt or whatever it may be, the old days of ATF 4 fitting everything are long gone.

Yeah I think I'm agreeing with you, at least for the Genesis. Other cars, I don't mind doing Valvoline (like my wife's '15 Santa Fe), but for the Genesis, I'm thinking I'll do OEM fluid.

I tend to be OEM but used Amsoil CVT fluid in my Accord and it's smoother than new.

I have 40K on my '15 Gen. How soon should I do ATF, diff, and any AWD fluid?

I did my diff at 30k and just did trans 34k. I plan on keeping it.

Did you DIY? Any tips and tricks or pretty straightforward drain and fill?

Four years later, the Hyundai RR (rear wheel drive) ATF is now $18.50 a Qt. A Qt of Mobil 1 ATF is $8 from NAPA, a gallon of Maxlife is $26. Both advertise they are IV-RR compliant. I ordered the Maxlife from Wal-Mart, but it appears to be OOS at the local stores.
