Which transmission fluid did you use? I hope it was not the Valvoline Import (Blue Quart Bottle). Because that is Hyundai/Kia SP-III. You should use the Max life red Valvoline bottle. That is compatible with SP-IV. Your car calls for SP-IV if I am not wrong. SP-III are thicker fluids. SP-IV are thinner fuel efficient fluids. Please confirm this and make sure you used the right fluid :)
Great video man. I need to change the trans fluid on my '12 Elantra and I had a couple questions. After how many miles did you change the fluid? Mine is over 120k right now. And did changing the fluid cause you to start slipping gears? I know that's a risk if you wait too long before changing the fluid.
How often do you change transmission fluid and what type do you use? I've read to use the Hyundai SP-IV fluid but it's so expensive. Thanks for the vid!
My fluid was just as dark, I didnt want to do any damage so I just put it back. I have 120k miles in 2 years and it has never had the fluid changed. Did you experience any issues after this change?
