Changing Transmission Fluid

[Mark_888]

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.

In the 2009 Owners Manual it does not ever call for replacement. I would not change it if I were you. Transmissions with synthetic fluid are designed to go much longer between fluid changes than conventional transmissions. The procedure for changing them is also much more difficult, partly to discourage you from changing it.

I don't understand why dealer needs to "check" trans fluid at a certain mileage. Trans fluid level can NEVER go down unless there is a LEAK. Dealer checking is just an excuse to sell you something you don't need.

Seems like you answered your own question....they check level for leaks. However if it is contaminated they will recommend a change...but I would have it checked somewhere else.

Good news for 09 Genesis 4.6 owners. I work at a Hyundai store and my service advisor has done the research and the severe service tranny flush starts with the 2010 and later models. This means that the warranty is good for 100,00 miles on the 09 model.

I don't care what any manual says. Any "lifetime" fluid is no good.

That is correct. "Lifetime" fluid fills on transmissions is a myth. Most modern transmissions will survive to 100k miles. Guess what? Past that is the point at which no one warrants them. No matter who makes it, if you wait until the fluid is dark, and especially if it smells "burnt", you and your transmission are all done. Changing the fluid at that point nearly guarantees failure. I've had a couple go 200K+, but they were serviced at much shorter intervals no matter what the dealer recommended.

If you're going to get rid of it before 100K, who cares? If you know you'll be into the car much past that, do the service.

 

[Philth]

Personally, I'll be changing mine every 50k

 

[veed]

you really think it's that critical, eh? (serious question here - not baiting)

 

[Philth]

Yes. Take BMW and their lifetime fluid. Transmissions were failing left and right.

 

[veed]

point taken. cheers.

I agree with you 100%. I do the first service at around 75k then every 50k after that except for my 4wd Suburban that I change every spring to get ready for towing the boat. I have drive cars to at least 200k and up to 260k and not one transmission failure in the last 36 years.

Just for giggles - call your hyundai dealer and find out how much for a full transmission flush. Then report back here and let us all know....

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.

Thats cheap as shit.... the dealer wants $72/qt

How many quarts does this tranny take?

$349 for a 100% fluid replacement. (Not just a drain and fill)

not that it is an amount to laugh at, but $350 seems worth it for the peace of mind that it is done right and documented. That way if it fails, you can throw it back on them.

The way i see it is that amount is about half of my car payment, or about the price of one high end tire. a small price to pay for the peace of mind, and not having to deal with sourcing the oil and getting filthy.

 

[Philth]

Exactly. About $350 is what the dealer charges to change the DSG fluid in our VW Jetta TDI, and that's every 40k miles.

Given the price of the transmission for my Genesis, there is no way in hell that I'm waiting 100k miles to change the fluid.

my camry has a "sealed" transmission that allegedly has lifetime fluids. I dont buy it. I found a process that involved having the fluid at a certain temperature and having the computer connected to the transmission while the fluid is changed to avoid over or underfilling it. Apparently the process is quite expensive and my dealer told me I did not need it. I dont believe a lubricant/oil can be a lifetime fluid. The car is at 83k mi, I plan to keep it to 150k. I likely wont have any problem if i dont change it, but if i can spend $500 to do it, i likely will.
Since the camry is now my wife's car. I dont want to get a call from her while i am traveling saying that the car broke down.

I would rather spend a little more in prevention than a lot more for a cure. The peace of mind is worth it to me.

 

[EXBMWGUY]

^ Yes. Makes good economic sense, plus preserves personal balance sheet of man-points!

I would double check that they actually know what their doing. There arnt to many Genesis getting this work done so dealers and techs need to dig around for more information on it.

This thread it was touched upon a little bit. There were some wild costs too.
