Timing belt or chain?

[Joebruno127]

My 20116 3.8 genesis has about 97000 miles. Do I need to get a timing belt or chain done? The shifts have been a little rough. All of the fluids have been changed. I am going to be running Redline S-1 through the engine tomorrow. Any other maintenance you have done which is good?

It's a chain haven't heard anyone doing a chain. They are pretty stout. Did you do your diff yet?

Yes I changed the fluid.
I did the oil, transmission, coolant, and brake.

You should be good. Check the ball joints and the rubber bits under the car. The harsh shifting could be a couple of things. I know the second gens have a harsh shifting issues due to the solenoids there's a tsb. I think you have a ZF if I'm not mistaken correct me if I'm wrong. Did you use specific tranny fluid or did the garage throw in whatever it had? You can try friction additives. I'm a huge supporter of catch cans on Direct Injected engines. They help keep the valves from gunking up.

Do you have the tsb?

I was wrong about the ZF. The fluid you used seems to be the one for the coupes.

The 2009-2011 Genesis 3.8 V6 used an Aisin 6-speed Transmission. Aisin was a joint venture between Toyota and Borg-Warner to build RWD transmissions, and was used on Lexus and other cars. Based on member feedback, this transmission has also proved to extremely reliable.

Get that fluid swapped out immediately. Your transmission requires ATF 9638. I'll link a thread give it a read it has a lot of good info for you. These transmissions are really picky on what fluids you put in em.

2012 Trans fluid change

Any videos out there? I read it's a 5 qt drain. Is there 1 drain bolt and 1 fill hole? I have 60k miles

Ya alot of that shit on the big box stores are universal fixes which is a no go for our cars or many others. They will work on our cars but lack the other additives. Check these guys out. Their customer service is top notch too! Send them a message stating your situation they'll help you out!

So the filter is built into the pan, they sell a kit with the fluid and new pan/filter assembly you might wanna look into that.

So I checked on vavoline and they say it is compatible.
I am trying to make sure it is right. How sure are you it is wrong.

Yes it'll say it's compatible but it probably won't meet Hyundais standard which might cause the transmission not to function properly like I said before these transmission need a specific fluid if you but a universal atf fluid in it will work but it won't work well causing rough shifts, jerking etc. There's a reason why the Valvoline was 10$ a quart and the the stuff Hyundai calls for is $20 a quart.

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.
