Good SP-III fluid with fast delivery.
Didn't want to go to a Hyundai dealer, so I ordered this. A little expensive, but my 2009 Santa Fe is shifting great. Swapped 5 quarts now, and will order more soon to do a second drain and fill!

Óleo enviado é muito antigo
Data de fabricação 03/2024, é muito tempo após a fabricação, veio com adesivos soltando, possivelmente devido a ficar exposto ao calor. Devido a isso fiz a devolução.

Excellent fluid for long transmission life
I used this ATF in our 2008 Hyundai Santa Fe with 41k on it. We bought this car used and the owner was older and did the oil changes and filter replacement regularly but was discouraged to change the ATF by her mechanic? She told me that when I bought the car. I admire her honesty. I am a mechanic of over 20 years and heard almost all of the myths associated with car/truck repair. The vehicle was in near new condition except for its transmission fluid condition. I researched what was needed for the application and bought this fluid on amazon because it was highly reviewed and worked well in this vehicle. Hyundai uses a Mitsubishi sourced transmission in most of this era vehicles so there fluid is required which is SPIII specification like most other Mitsubishi transmissions. There own fluid which is diamond queen SPIII Is very expensive and sometimes hard to find. I’ve replaced many Mitsubishi transmissions in trucks using the same fluid and people use the wrong fluid all the time costing them thousands of dollars and downtime because they use the wrong fluid or never change the fluid at regular intervals. I actually purchased 6 quarts of this fluid for this fluid change but it only requires 4.6 quarts. Do yourself a favor and drive the vehicle first to get the fluid warm or hot and drain the transmission while warm or hot, Do not burn or scald yourself!!! Use protective equipment like gloves and face protection! The drain plug has a magnet built into it and catches all the metallic shavings that occur inside your transmission and will collect most of it for removal when you drain the ATF during the service. You will need a thin wall box end wrench 15/16” or metric equivalent to remove the drain plug. Some mechanics use a thin wall ground down socket to initially loosen the plug then remove by hand as I do. Clean the drain plug before reinstalling it and refill the trans with 2-3 quarts before starting the engine and fill the remaining fluid until the full cold line is reached on the dipstick. While the car is in the driveway running, put the transmission gear selector into all the different gear selections and then return to park. Drive the vehicle until the normal operating temperature is reached. Return to your house and check the fluid level for the HOT level, add fluid as necessary.
