Transmission Fluid Exchange at Suntrup Hyundai in St. Louis, MO

Transmission fluid is one of the lesser-known fluids within your vehicle, but also one of the most important. It serves as both an oil and a hydraulic fluid, to lubricate the metal parts and bearings within your transmission. It prevents overheating and grinding while facilitating the shifting of your gears. This key fluid, however, can deteriorate over time, causing the contaminated material to coat the parts of your transmission like sludge. If you haven’t had your transmission fluid exchanged recently—or perhaps ever—then now is the time to do so. Schedule an appointment at Suntrup Hyundai and we can exchange the fluid for you, along with inspecting your transmission. Preventative maintenance now ensures your transmission will continue to operate as it should.


How Often Should the Transmission Fluid Be Exchanged?

The buildup of contaminants and debris within your transmission fluid can lead to a lack of lubrication and decreased effectiveness in cooling the transmission’s critical parts. Unfortunately, this can lead to transmission failure. To avoid costly repairs and potential transmission replacement, our certified technicians at Suntrup Hyundai recommend you have your transmission fluid be exchanged approximately every 20,000 to 65,000 miles. The timeline depends on your driving habits and Hyundai model, so be sure to check your owner’s manual or bring your vehicle in and we can take a look. The type of transmission within your Hyundai, the environment in which you typically drive, and the loads you carry or tow, can each affect how often you should have your transmission fluid exchanged.

What Does a Transmission Fluid Exchange Include?

It is important to note that fresh transmission fluid cannot simply be added to the old, contaminated fluid, as this can cause debris to clog the filters, limiting flow within the transmission. Instead of “topping off” the fluid, our certified technicians will completely drain the old fluid following the addition and circulation of a transmission cleaner. While the old fluid is being extracted, new fluid will simultaneously be added to the reservoir. Once complete, our technicians will verify the fluid is at the appropriate level for your particular vehicle.

Indications That Your Transmission Fluid Needs to Be Replaced

You likely need to have your transmission fluid exchanged if you notice one or more of the following indicators:

  • Your transmission doesn’t engage
  • Your Hyundai won’t stay in gear while driving
  • Delays and decreased performance when shifting
  • You notice a burning odor
  • Your dashboard warning light(s) come on for engine maintenance and/or high transmission temperature
