What type of transmission fluid is used in the sonata 6 speed automatic? SP-3 or sp4? Is the transmission fluid compatible with Mopar sp+4 or not?

There are suggestions that transmission fluid in the 6 speed should never be serviced, I am skeptical about this rumor. I have not seen any fluid thats completely immune to viscocity breakdown.
The Mopar sp+4 is cheaper than the honda Z1 which recommend 100,000 mile ATF change.
A transmission rebuild cost thousands of dollars, and in comparison changing the ATF can cost at most $400 at a service station and $75 if done myself.
I don't know if anyone share my opinion, but i feel better if I serviced my transmission rather than neglecting it and have the transmission fail earlier than expected.

I plan my servicing schedule well before hand. Since Haynes maintainence manual won't be release for number of years, hyundai forum is where i gather information and dispell rumors.

from what i gather sonata YF require sph-IV ATF not SP-3 which were used in 2006-2010 model year sonata.

instead of speculation why not just show up at your local hyundai dealer's parts depot and buy it direct??? I wouldnt use anything but OEM fluids anyway?

If i am not mistaken, newmarket lubrication provide all modern transmission fluid to chrysler, ford, GM, toyota, honda and hyundai. Newmarket uses the very same base stock for all modern Automatic tranny fluid with manufacture specific additive package for each brand. It also provide the multi vehicle lubricants for castrol, vavoline, quakers and penzoil, where one formula satisfy multiple manufacture specificiation for lubrication.

Its obvious that dealer formula can't go wrong in your vehicle, the question is when i can get an sp-IV compatible newmarket multi veihicle tranny fluid for 1/3 cost at Walmart, why would I want to pay 3x cost from the dealership. On top of that, I can afford to change tranny fluid more often for example every 50,000 miles at 1/3 cost.

Genesis and veracruz seems to be the exception to the rule, as you know they outsourced the transmission for $30,000 plus Hyundai. They use high end shell m1375 and can't be replaced by off the shelf ATF.

Yeah, there's no such thing as 'lifetime' fluid... unless you want the life of your tranny to be pretty short :grin:. This is especially true in a hot climate, like TX.

Now, I have to correct you in 2 statements you made. Honda has never advertised a 100K tranny fluid change interval. They have a 3X drain every 30K interval, but you'd be crazy to even do that in a hot climate. For the same cost, I do it 1X every 10K miles; that way I always have semi-fresh fluid in there. The reason for the 3X is Honda doesn't have a torque converter drain plug (very few cars have it), so less than half the fluid gets out with every drain, hence requiring it THREE times in succession. MUCH better to do it once every 10K miles for the same money. Oh, and the second correction is the $75 price tag to DIY. My Hondas only need 4 quarts at best, and I always buy it for $5.25 locally, so it's about $25 after tax. I also have to comment Honda is probably the only manufacturer NOT to use planetary gears on their trannies, so they're a lot less robust, needing more frequent oil changes. And also that's why they require a special oil, and prefer not to gamble with anything else. With a typical planetary gear tranny like on the Sonata, as long as you buy the specified oil (SP-4, I believe) you should be fine; no need to use OEM tranny oil, just like the majority of us don't use OEM motor oil.

Finally, I'm sure the Sonata doesn't have a converter drain plug (I've only seen RWD vehicles with them, and it's a royal pain to get to it when they do anyway), so I assume you can only get out the typical 4 quarts at best when draining the tranny. For that reason, I plan to change the oil every 15K miles, but man, what a PITA it'll be on this car, with no dipstick. There's a TSB floating around on how to check level, and I have the procedure from the service manual, but no mention of how much oil is required for a drain & fill. Car has to be running, on a FLAT surface, at certain temperature, and with the check and fill plugs removed.

What I plan on doing is removing the belly pan with the car on ramps and engine cold, and let the tranny drain (without spilling anything) until nothing comes out. Precisely measure how much fluid came out, then just fill the same amount of new fluid and call it a day. But knowing me, I'll probably want to check it anyway. To do that, I'll remove the check and fill plugs, raise the car with my floor jack, remove ramps, lower car to the ground (with no belly pan, of course, or can't use a floor jack), and follow the manuals instructions but using an infrared thermometer rather than a dealer interface we don't have, and verify the amount that drained is the right amount to fill the tranny. And next time no need to check it. Without checking level is going to be a much quicker job. Now, if most of the fluid comes out, which I hope to learn from here before it's my time (don't use the car much), then I might do it every 20 or even 30K miles, but oil is so cheap that why take chances to leave it more than that? I'd also like to know if fluid is fully synthetic or not. Take care gang.

Do you have a way of posting the Manual here? I don't really care, as I have been asked to leave by Bingo Bob Steve anyway.

Some members wouldn't even think of consulting the Owners Manual, & will pour almost anything in and contaminate the Transmission. :banana:

By the way, the quality of your posts have been exceptional! :thumbsup:

Mopar tranny fluid? Are you trying to kill your car?
Some of the new owners have absolutely no clue on what they are talking about or what damage can happen. Plus isn't it is a sealed system? I guess these Threads are fun, but all it takes is one Owner to take the Mopar like advice given here and blow his Transmission and void his Warranty

No, it's NOT a sealed system. Anybody with mechanical knowledge knows no oil is going to last 100K miles, which is the minimum expected life of a tranny. In fact, not even close in hot climates. Hyundai recommends 60K-mile interval for many instances, throwing your 'sealed' theory out the window.

And FYI, Mopar doesn't make oil, so it's no different that what you can find at your friendly auto-parts store. As long as people use the oil recommended for the tranny, nothing is going to happen if you know what you're doing. The procedure for the Sonata is not an easy one, since tranny does not have a dipstick. But for people like me who have done their own maintenance for decades, and have the right tools, knowledge, and a service manual, it's not hard at all.

Rather than jumping on people's backs without knowing what you're talking about (it's about the 3rd time I read a similar comment from you), you should take the time to learn. Or simply skip these threads if you're not into DIY :grin: . You seem to be the kind of forum member who brings the worst in people, who have nothing positive to contribute, and who usually cause other members to get warnings when defending themselves, and since I don't want to be the first one, you'll have the pleasure of being the first in my ignore list, so don't bother with a response that could get you a warning :innocent:. Good day man.

Correct me if I'm wrong, but doesn't Hyundai advertise it as a sealed system with no maintenance required? If so, then they'd be on the hook for any problems that arise during ownership. UNLESS you do something not suggested/required by the owners manual like changing the fluid. If I was going to keep it beyond the 10YR/100K power train warranty I might consider it, but other than that????????? I've been researching this car for a while and I do recall reading it somewhere.

I didn't make this up, this recommendation came from my haynes maintainence manual. (60 month) 160,000 km which I converted to be 100,000 miles. When i read it, I was sceptical about the interval but didn't question it since haynes advice hasn't done me wrong.

With regard to the 75 dollar that includes oil pan funnel and wrenches.

Transmission fluid is made by a few big company like shell and newmarket, then badge them whatever brand they sell it to with some additives specific for the brand. A bottle with Mopar on it doesn't mean they are made with urine, as long as they're sp-IV they should satisfy the requirement.

No and depends. No system is really 'sealed' since you need to add oil somewhere, but the term usually implies no drain plug, so changing fluid is a royal pain since you'd have to suck it (I have tools for that too :grin:). Thankfully, our tranny has everything you need to service it: a drain, check, and fill plugs.
Now to the other issue. Hyundai says no maintenance required under 'normal' conditions, but adds a laundry list of 'severe' use that will affect most folks, and that requires changing fluid every 60K miles. Read your manual; it's in there. Severe use includes hot climates, dusty climates, extensive idling (traffic), driving short distances, etc.

The lack of a dipstick makes the fluid change job harder than it has to be, but it's well documented on the service manual. People like you will probably never do it, but that doesn't mean you should not get it done at some point if you want your tranny to last what it could. There's always a lot of crap on a new engine/tranny/etc that contaminates oil, not to mention the initial wear any moving parts will have, so leaving that oil for even 60K miles sounds crazy to me. You're talking about $30 to change the oil yourself (depending how much oil drains out, which we still have to find out); it's cheap insurance IMO. BMW recommends changing engine oil every 15Kmiles. Am I going to follow that? H E L L no :grin:. But before they started paying for maintenance, do you know what was their recommendation? 3K miles. I do it 5 to 7.5K miles, since it holds 10 quarts of oil. I go 5K on my other vehicles. It's all a matter of preference.

Finally, will your car blow up if you don't change your tranny oil? No, but you'll shorten its life depending on your climate and use of your vehicle. I'll probably never put 60K miles on this car, but I like to maintain my vehicles well regardless of plans. I just try to be in the middle: not the ridiculous intervals suggested by manufacturers (they want you to buy new cars after all), nor ridiculously short intervals where I'm throwing my money away and not helping with the environment. It's a balance each of us find at different mileages. I just have to say you should know what you're doing, so for somebody like you who have never done any maintenance, doing a tranny oil change on this car is definitely not a first time project, but you can always learn by getting together with somebody who does. It's a nice way to learn and enjoy some camaraderie. We do that all the time with motorcycles, from changing brake fluid on BMW bikes with servo brakes (11 bleeding valves) to adjusting the valves. You can always post on regional boards for local owners. At least in my case, more than the savings, it's the satisfaction I know I'm doing the job right. No tech is going to treat my car like me, and most of the time it takes me less time to DIY, and I can do it whenever I want. I simply enjoy working on my vehicles, and checking things while I'm under the car, cleaning everything around, etc. Take care.

When a transmission does not have a dip stick it's considered a "sealed system", thats a fact. That does not mean that you can't service it, manufactures provide techs with a way of checking for proper fluid levels for a reason. Lets not forget that there are transfusion machines that tap into the transmission lines to perform the service. It's not always a drain and refill method. There are manufactures that don't recommend transmission fluid changes as the fluid is "designed" to last the life of the car, an example is the Toyota Prius. Was that decision made because they trust in their design work? or because it's a selling point i.e fewer maintenance? , I could care less.

Would I follow that recommendation? No, I know better. I would flush my fluid, and have so, every 30K miles on all my cars.

I don't see anything wrong with someone wanting to know what type of fluid the transmission uses or at what interval it should be flushed even if the car currently has 21 miles on it. An educated owner is a good owner I always say.

I don't understand all the hating in this forum from some members when a member asks a question they don't have an answer to. If it bugs you that much then leave.

Just use the right Fluid and knock off the Insults. If you want to ignore me 'elp' that's great. Not too worried about getting a warning, nor being ignored by you? Why would I be warned anyway? :whistling: But I do thank you for your warning. Enjoy your Sealed Transmission!

Manual transmissions don't have a diptstick and are not sealed. A transmission is considered 'sealed' when it does not have a drain plug; get your 'facts' right. The reason many automakers are not installing a dipstick anymore is to prevent idiots to put engine oil into the transmission (or viceversa), and then having to pay for repairs due to not being 'properly labeled'.

This thread was about what oil to use, not if the freaking transmission was sealed, semi-sealed, unsealed, or whatever. Geez. Another one to the ignore list.

Bottom line is if somebody cares about his/her car, tranny fluid should be changed at 30K miles, but to each his own. That's especially important if you live in the hot (and dusty) desert southwest. A bit of reading would educate people about why. I'm out of here; had enough of trolls who don't even own a Sonata but have 'expert' advice.

Good advice, my accord is already 40,000 miles on the odo, screw haynes recommendation, I will be changing it this weekend. :liebe011:

Oh, it's okay for you to chirp about the subject but when your corrected on your lack of knowleadge then people should drop it? That makes sense.
 
Ignore list? That's what I get for not falling in line with the local car "expert".

Transmissions with no dip stick have NO DRAIN PLUGS for the most part, hence sealed units. Again car expert, get your "facts" straight, no dip stick stil = sealed unit.

I'm sorry, I forget you were at the auto meetings when this decision was made. It's not like there are other benefical reasons to the auto maker for adopting this system, again reading will give you the "facts". 

Why is it that DYI individuals are always so pompous and repulsive.
