Changing Transmission Fluid

I am not an expert in automatic transmission maintenance (or little else), but the owner's manual for the 2012 Genesis 4.6 does not make a distinction based on transmission type (or engine type). It only states to use GS ATF SP-IV-RR specifically approved by Hyundai. On Amazon, the Genuine Hyundai Fluid 00232-19052 SP-IV-RR Automatic Transmission Fluid - 1 Quart is less than $19 / qt. Confusing on what to use IF we decide to change it at 60K in the future.
From 2009-2011 the Genesis Sedan used a ZF transmission for the V8, and an Aisin transmission for the V6. These require different synthetic transmission fluids. Both ZF and Aisin are very respected names in transmissions and their products are used on many other brands, including BMW (ZF) and Lexus (Aisin).

Starting in 2012 the Genesis sedan uses the same Hyundai 8-speed transmission for all engines, and it requires a specific synthetic fluid. I would contact a Hyundai dealer parts department for the correct part number.

The fluid part number deadrun listed above is the correct fluid according to my 2012 Genesis shop manual, page 27, for all 8-speed Hyundai- produced transmissions on 2012 MY cars.

I'd be curious what is cost at the dealer. Next time I'm there, I'll ask them. Usually, fluids on Amazon aren't too cheap.
 
Thanks for the advice. Lol

No problem... I should have been more aware of your signature too. We have totally different transmissions. Thats probably why I've gotten much higher quotes and a lot of blank stares when I inquired about a transmission flush.

The three local dealers near me had to call me back with information. They all called back with the same answer too...
 
Thanks all for the posts since I'm going to do a drain and fill soon (50K miles). I live in South Florida and go lotsa miles with my cars. Since doing the periodic fluid changeout in my cars, I've never had an ATF problem. I would like to comment on some of the things I've observed above:
1) a dealer can never void a warranty if you use the proper product, regardless of manufacturer as stated by one who posted above due to a federal act precluding such nonsense. The important thing is keep your records - especially that which proves it meets the spec. Also remember most service writers are commission salesmen - unfortunately half of them have no clue, the other half are driven to sell you services so they make more money. Be an educated consumer. Yes, per the manuals - you "never need to change this fluid".
2) I don't believe Mobil 1 synthetic (a product I really like) meets the Hyundai V8 ATF spec (Shell spec M-1375.4). It meets others. The ATF specifications have evolved to many varieties these days - I still have trouble finding fluid for my Kia Sorentos. Unless Mobil can provide a spec sheet proving otherwise - their web data says this fluid does not meet the M-1375.4 spec. I've not done a technical comparison of the Mobil 1 requirements vs. the M-1375.4 spec., however I will not buy it for this car (and really wish I could).
3) Great tip on the Castrol - I went and checked that fluid today because Advance Auto's website said it worked, however on the Castrol website it does NOT list the M-1375.4 compliance. I'll push them to get written proof - great tip.
4) It appears that one of Ford's fluids (Mercon SP compliance) meet this Shell ATF M-1375.4 requirement - I'll leave investigation to you folks to the following article that turned me on - http://forums.bimmerforums.com/foru...nsmission-Fluid-(ZF-Lifeguard6-Ford-Mercon-SP)
5) The shell fluid purportedly is not that outrageous in price and clearly meets the spec if you're interested. I've not yet found a good place to buy it.

If anyone finds a place that sells a fluid labeled to meet the Shell ATF M-1375.4 spec for less than $10 per bottle, please advise.
 
Update to prior entry - I just got off the phone with Castrol. The tech service rep there says they do NOT, repeat do NOT have a fluid that meets the Shell M1375.4 spec. What a world we live in. Unfortunately I'll only use fluids that document in their published literature that the spec is complied with. I've tried to speak to a human in the US regarding the Motorcraft product - that does not appear to be possible (live chat broken, no phone number, local Ford dealer clueless, actual bottle says nothing...).

One thing people need to understand is that the specs for transmission fluid are not necessarily: good, better, best. It is not correct to say that one spec is better than another, rather some transmissions just require a different type of fluid. Obviously, all of the transmissions used for the Genesis require a synthetic fluid with the correct matching specs, even if one is not necessarily better than another. Unlike engines and motor oil, transmissions do not try to completely eliminate friction, and some transmission oils may not allow enough friction for it work correctly.

When it comes to which fluid manufacturers make the correct fluid for a particular transmission, it just comes down to how big the market is for that fluid and whether they think they want to compete in that market. And even if Castrol in EU did market that product, Castrol USA may have decided to not import it. BTW, Castrol is a division of BP.
 
Red-Line D6 ATF documents compliance with many specs including the Shell M1375.4 spec. http://www.redlineoil.com/product.aspx?pid=115&pcid=9 It is retail $11.95 and fully synthetic (you can get it from Amazon if you want - free shipping over #35). My bud can get if for less than $9 per quart - I'll go through him. I've used Redline products for years and have had good results.
Anyone know how many quarts in a drain and refill?
 
I have a 2012 3.8L genesis with the new Hyundai-built 8 speed transmission. The manual mentions inspecting the automatic transmission fluid every 37,500 miles, but doesn't mention the interval to replace the fluid.

Just wondering if anyone has recommendations on how often the fluid should be changed.

Thanks.
I just had my 2015 3.8 genesis in for 60000 mile checkup and was told they don't change the flued because it's a sealed transmission

"Sealed" transmissions can still be serviced, they just to not have a dipstick.

Another example of lack of knowledge and training of tech's at a dealership. No oil or fluid is lifetime. Unless like i have stated before, lifetime = 100,000 miles.
 
Looking to update and upgrade your Genesis luxury sport automobile? Look no further than right here in our own forum store - where orders are shipped immediately!
The book says "inspected" at the 36K mark. (I think its at the 36K mark). If your dealer says you MUST change it before the 100K mark, they are trying to take advantage of you. Don't get me wrong. Changing it is a good idea, but the owners manual does not say anything about changing before the 100K mark.

As I've said before, the Hyundai ATF for the ZF Transmission costs about $75 a liter or quart. Don't know how much the Hyundai ATF for the Aisin Transmission costs.

In navigating through the www.thectsc.com site mentioned in earlier posts, I see that their ATF says right on the bottle "ZF - Lifeguard Fluid" and that it is made just for ZF Transmissions. The ZF-Lifeguard fluid for the ZF 6HP26 transmission is Lifeguard6 fluid, ZF part number S671 090 255 01 and is for ZF transmissions used in Audi, Bentley BMW, Jaguar, Land Rover, Maserati (all these have a manufacturer part number assigned) and most of all,
Hyundai (oil no. 040000C90SG). (They also have a ZF-Lifeguard8 listed for those cars with the ZF 8 Speed Transmissions).

Lastly, I read somewhere on the site, (or it may have been in the www.bobistheoilguy.com site) that the ZF-Lifeguard6 fluid is CLEAR, not dyed red like other fluids. Best of all, this ZF-Lifeguard6 fluid costs $17.13 a quart/liter, not the $75.00 that Hyundai charges.

If you change fluid while still in warranty, the above is the way to go.

If you change fluid once warranty is finished, you can do like my Jaguar buddy and use Mobil-1 Synthetic ATF. He is happy with it, and many on the Jaguar and BMW BB's are using it.
How many liters for fluid drain /refill on 2010 genesis 4.6?
 
Here's a screenshot from the owners manual that should answer your question:IMG_0135.jpg
 
RockAuto.com has LiquiMoly fluid for $5.84 a liter (meets spec) and PartsGeek.com has a ZF pan for $67.58. RockAuto also has a 20 liter LiquiMoly for $102.79, but that's good for at least three changes. I wouldn't go by the total volume because there's quite a bit left in the lines and cooler. I believe the amount for a drain and fill is about 6.5 liters at most. There's videos on YouTube where people service the ZF 26HP transmission on BMWs (It's the exact same transmission as what's in the 4.6). My mechanic said he'd charge $90 for the labor.
 
Bumping this old thread instead of starting a new one.

I am the second owner of a 2011 Genesis 4.6 with 131,000 miles. The car is driving perfectly (knock on wood) but as I've never changed the transmission fluid in it, I think it's way past time to address the issue.

I called several local transmission shops who recommended just drain and refill the transmission fluid for around $150.
Two shops said they would drop the pan, replace the filter, and re-fill, for around $225. I've very dubious about what they are actually going to do, as it's my understanding that the transmission filter is built into the pan. Can they install new pan/filter, plus the correct fluid, plus labor, for $250? After reading this whole thread, something doesn't smell right, but I know nothing about transmissions.

I then called a Hyundai dealer in central FL, and whoever answered the call in the service dept suggested I have the transmission flushed (something that several people here on this forum specifically recommended NOT doing). I then asked to speak to the Service Manager and explained my situation. He took my name and # & VIN # and said he'd look into it and call me back. The following day he did, and quoted $1,200 for new pan/filter, miscellaneous parts and hyundai transmission fluid at $78.4/quart. He said he would have to order in the transmission fluid as they didn't stock it. I asked him why that was, isn't transmission fluid a routine maintenance product, so why don't you stock it? He replied that they "rarely" change transmission fluid as it's a "lifetime" fluid, and very few owners choose to do this once they learn the price. Presumably dropping the pan and replacing the trans fluid isn't rocket science, but I'm concerned about sending it to a repair shop that (according to them) "rarely" does this.

Since there are no warranty issues to consider, if I don't want to pay $78/quart for Hyundai Genesis transmission fluid, is there a consensus as to what is the best replacement brand of transmission fluid to buy? Which of the brands below are best for a 2011 Genesis 4.6?

Lifeguard 6
Mobile-1 ATF
Valvoline Maxlife Full Synthetic
Ravenol
Red Line

Is this site recommended? genuine-zf: The CTSC

Thanks in advance for any replies!
 
Just called a Genesis dealer in central FL--they too recommended "drain & fill" for $215, they said the transmission filter is an "unserviceable" filter and doesn't need to be replaced. Is there really such a thing as a filter that lasts a lifetime??

I then asked them what other preventative maintenance is suggested for my vehicle at 131,000 miles; they replied:
Fuel Induction Service
Coolant flush
Spark plugs & coils
Timing belt
Serpentine belt
Drive belt

Appears that it may cost me some coin to keep this car!

This seems to be an unpopular opinion, but I think there is. Some are really just metal screens and if there is enough gunk circulating in the transmission to clog them, you're going to need a new transmission anyway.
