I think Todd did a write-up once on how to use the oil dipstick to check the trans fluid levels?
Yea, you can use the oil dipstick, but it's only going to tell you that it is staying the same. Whether it's low or high, you need Jeep to check it. Here's what I do though:
The CVT fluid is very temperature sensitive, so you want to always check it after a good long drive (like after your drive to work or some similar long commute). You want to also park in a level spot, and in the same spot each time you check it.
Leave the engine running and put the transmission in park. Set the handbrake as well for safety.
Pull the CVT fluid tube plug and pull your oil dipstick. I clean off the dipstick using a paper towel with some windex on it, just to make sure I don't add a little engine oil into the cvt fluid.
Insert the oil dipstick into the trans tube and fully seat the handle into the top of the tube (you can't push it down any further). Now pull it out and read the level. On mine, it came to just below the "low oil" mark on the dipstick. This was a few days after I took delivery of the Jeep, back in 2008. If it's very cold or warm outside, expect it to move slightly up or down on the dipstick, but it should still be visible.
Again, this won't tell you if it's at the correct level, but it will let you watch that it doesn't change drastically. If you notice a drastic change, get to a dealer and have them check the fluid level.
