So I finally got around to changing the tranny fluid in my 2007. It went very easy just like a regular tranny. I dropped the pan slowly to let it drain into a pan so I could measure it. I dindnt spill one drop. I replaced the filter also easy just 3 bolts. Cleaned the 2 magnets in the pan, cleaned the gasket surfaces and reinstalled the pan. I measured exactly 5 1/2 qts. I poured it in, ran the car for 5 mins, shifted thru the gears a bunch of times and used the special OEM dipstick and graph and it was within spec. So I took it on a 5 min test drive. No unusual noises just nice and smooth. Check fluid level again and it rose a little from the heat and looked perfect.
I don't see why people are so afraid to do this and pay extra from the dealership.
Drove it to work tonight and drove mint. I only paid a total of $125 for the fluid and filter. I just love eBay and RockAuto.

That's awesome, glad you were able to do it yourself! Don't suppose you took any pics during the process? Would make a good how-to thread for those who may not be comfortable trying it themselves.

Looking at the graph to temperature relationship. The fill level is pretty tight and highly temperature dependant. Getting it right and/or in the normal range (which is not clear) is pretty tight. A optional dipstick is required and temp which would change upon draining it.

nI my opinion given the fact that this tranny is 2x the cost of a conventional automatic and clearly a bank breaker. I would not be looking to save the hours labour to have it done by a Pro. Simply not worth it.

Your conventional automatic has a wide level that it will operate in without issues and can easily be check monitored but not the CVT. Its sealed and the fluid level has to be 100% and linked to the temperature which the Pro uses a scan tool and tweaks the level until bag on. I am all for keeping that 100 bucks in my wallet but at the risk of burning out the bands or blowing seals (whatever might happen when not right). My sleep or loss of it is not worth the savings on so many levels. Beside if you met Murphy when DIY repairs you'll know what I am talking about. Also since the fluid change is a very long cycle you only likely to do it once in the vehicles lifetime. I believe a Chrysler rep said it was 120,000km. As for me I'd take it to a competent dealer for that operation.

i might try and drop the pan next time like u did

i took it to the dealer a while ago bc of all the talk of how hard it was to do it.

ill need to get that special dipstick though. if u put back in exactly what u take out i dont see how it could be a problem? although ur only changing a portion of the fluid that way and not all of it but 5 1/2 quarts of fresh trans fluid every 30K miles or so can only be good right

If there is a drain plug or can be siphoned out the filler would be better. Having something to measure it accurately is a must but what I don't know off hand.

If its dropping the pan like other transmissions its extremely unlikely to catch it all and not have a driveway slick. If you use a small swim pool maybe. LOL but too much unaccounted for on the container and impossible to pour for measuring.

I'll see what other ideas appear. I am far from needing it anyway.

Just had my cvt fluid replaced yesterday at a cost of $255.90
I could have done it myself but my garage burned down destroying all my tools. Too bad.
Anyway this is the second time I had the cvt oil changed. One was near 120K and this time at 202590 miles. Believe it or not the cvt oil wears out. As it was last time I changed the fluid, I felt a marked difference in the way the tranny performs as I noticed also this time.
As the car accumulates mileage, and towards the high end, there seems to be some noticeable slippage of the band. This is why sometimes you get left behind by a Honda Civic or Toyota Corolla. With new fluid, the action is more solid. It pulls really good. I heard from one dealer that you never have to change the fluid of a sealed tranny. Baloney!

The bulk of the cost is for the fluid and likely filters. Getting the correct amount in there is key and for us its guess work. The use a metering tool as well as a computer interface analysing the temperature to get it right. They can also test that the setting are correct and drive is engaging as well as releasing at the right RPM's.

In my opinion you're only likely to do this change once given the millage for the change. I'd want to be certain it was bang on. Even though you'd save a few bucks.

I've not done my own regular transmission changes (take it to a shop). I don't want to deal or risk the mess and the shop steam cleans out the pan and face for the new gasket.

Thank you ronjr8102 from Worcester I was so undecided and afraid to do it myself. My Compass has 98,000 on it days after my fluid change. It went really smooth and I really didnt spill much either. The warning light is off and its running fine. The used car sales man didn't honor the warranty. The shop wanted $3,600 to replace the tranny. If it wasn't for your post I don't think I would have ever attempted it myself. Thank you so much!

Hi all, new to the forum. Just inherited a 2007 Jeep Compass with 94k miles and have combing it over. There are lots of posts and I wanted to demystify the CVT fluid change process. The process is very simple, just be sure to take your time. Follow posted instructions and you should be set. Here's the dipstick part number on Amazon: B07SSRGLG8 (can't post links yet) Remember to cross reference the temp + fluid level charts for the CVT.

A bunch of 10mm bolts hold the pan in, start from one end and you can drain everything out without a big mess. Three additional 10mm bolts hold the filter and O-ring in place.

Total cost:
$10 dipstick
$40 for 7qt of CVT fluid
$20 for transmission filter and gasket kit
