For those who don't know Idemitsu fluid is a major fluid/oil supplier for many car manufacturers. If you go to Kia/Hyundai dealer, you are pretty much buying the same fluid in a different bottle with Kia sticker. Nor Kia or Hyundai produce any oils or fluids. A local dealer wanted close to $30 per quart so I'm glad I found this fluid here.
Be sure to buy enough bottles so that you can fill and flush at least once. I bought 8 bottles. I drained the OEM fluid at 50k miles, it was black and smelled burned. Filled it with 4, drive for an hour, drained and it was better but still dark brown. Drained and filled with the remaining 4 bottles and it was much better. I can feel it shifts a little smoother.
I highly recommend this fluid especially at this price.
