I decided to replace my transmission fluid at 30K miles using the drain and fill method.
Here's a quick summary:
- Remove the plastic under panel (to include the small panel you remove during oil filter change)
- Drain bolt for the transmission is a 24mm (you can use a 15/16 if you don't have a 24mm)
- I drained approximately 3.5 qts
- Used Valvoline Maxlife Full Synthetic
- I don't have service manual, so I tightened the drain bolt to 35 ft/lbs (based on some YT videos on the
Palisade and
Sorento)
- I also removed the front fill plug just to make sure I can see the new fluid overflowing out during the fill
- I used a long funnel and filled from the top fill hole
- I've put approximately 3 1/4 qts when it started overflowing from the front fill hole
- I secured the front fill plug and added another 1/4 qt of fluid (8 oz) on the top fill bolt / plug
NOTE:
- I basically replaced the same amount that I drained (3.5 qts)
- Be sure to fill SLOWLY when filling from the top fill hole--it will overflow if you just pour the transmission fluid
- Go through all the gears and take it for a test drive
- Check for leaks
