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.

can I ask why you are considering a tranny fluid change on such a new car?? theres no way you have the mileage required to do such a thing at this point

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.

No, it's NOT a sealed system. Anybody with mechanical knowledge knows no oil is going to last 100K miles,

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.

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.

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