Dexron VI transmission fluid is used in a 2007 Hyundai Sonata. The Sonatas transmission fluid should be first changed at 105,000 miles. If You don't change the transmission fluid on schedule, You'll be lubricating Your transmission with metal shavings and other contaminants. This will shorten the transmission's life. It's important to regularly check the transmission fluid level between service intervals. Letting Your car run low on transmission fluid can cause the transmission to shift improperly or not at all. Checking the transmission fluid consists of pulling the transmission dipstick out while the engine is warmed up and running and with the transmission in park.

For automatic equipped cars, Valvoline MaxLife ATF is recommended. Be cautious when handling Automatic Transmission Fluid, as it is toxic and dangerous. Royal Purple MAX Synthetic Gear Oil 75W-140 is recommended for manual transmissions.
