How do I know when to change the transmission fluid in my Kia Sorento?

I just bought a used Kia Sorento and I'm not sure when the previous owner last changed the transmission fluid. What are some signs that indicate when it's time to change the fluid, and how often should I do it?

It's generally recommended to change the transmission fluid every 30,000 to 60,000 miles, depending on your driving habits and the condition of your vehicle. However, if you notice any unusual noises or vibrations while shifting gears, or if your transmission is slipping, it's a good idea to have it checked and potentially changed.

You can also check the color and smell of the transmission fluid to see if it needs to be changed. Good transmission fluid should be a bright red color and have a slightly sweet smell. If it appears dark or smells burnt, it's time for a change.

Overall, it's better to err on the side of caution and have the transmission fluid changed more frequently. Neglecting necessary maintenance can lead to costly repairs down the road. It's worth it to invest in regular fluid changes to keep your Kia Sorento running smoothly.
