you are right Kris....

Here is the link to the extracts of CVT system and How-to (for service guys) from SM but it doesnt indicate any filter at all.....
as you can see in the cross-sectional diagram of CVT


PS> please let me know if its illegal to share extracts from SM !!

I wasn't implying the it had a filter but leaving much of the fluid in the system as it would occur if an oil filter was left on after an oil change. I wasn't very clear.

I want "maxium flushage" for a tranny fluid change.... if that is even possible.

Interesting... what and where can we determine is the CVT detoriation date?

We've mused about this for a while now and no one seems to have come up with an explaination what this mysterious value is. It comes up on the CONSULT computer, but thats it. Apparently even high mileage MO's report a value in the low 1000's, and the limit is in the 100,000's. My guess is that its like the oil monitor on new cars - it doesn't measure any specific property of the fluid, but rather tallies up a "score" calculated from accumulated driving scenarios.

Eric is right,

howewer, I would still change the CVT fluid at least in 60k intervals. Smehow I find it hard to believe that fluid would last so long.......anyway, it certainly does not hurt to change it.

Gonzo-

I hope you are referring to the CVT fluid deterioration date. I want to believe the CVT itself will last quite a long time.

The CVT "brain" uses an algorithm to determine the remaining life of the CVT fluid. The Consult-II tool interrogates the brain and if the "CVTF DETERIORATION DATE" is greater then 210,000 the fluid needs to be changed.

Gonzo-

If you follow the procedure in the Service Manual and want maximum "flushage" the SM indicates "about 30 - 50% extra fluid will be required". That is quite a bit of $$$.

True but the CVT is quite a bit more of $$$.

Gonzo,

I believe that to do it right way you need to take off the CVT pan and clean it out. Then flash the system. And I do agree with you that the extra $$$ for 50% more CVT fluid is a small price to pay.

Just my 2c.....

well, i started working towards my CVT flush.... although at 47,500 KM, but still this deal was awesome.... a pair of 2 ton axle stands..... for 9.99$.... so i got 2 pairs.... will be handy for any other projects as well, i.e tire rotation etc

I had a set of $9.99 jackstands in the beginning as well, but quickly found that I needed some really beefy jackstands that could raise the car high enough (these only went up to maybe 14-15") to really work underneath it (without the crossmember being 2" from my nose) I opted for a set of high jackstands (20" lift) with 4 ton capacity. They cost around $50 a pair, but the extra space underneath made them really worth it. Matches nicely to the jack I use, which can lift up to the same height I think.

Get the rhino ramps from Walmart and just put in front of the front and rear wheels and drive up if you want to raise all four. Much safer and easier than sittin on four jack stands which leaves you with no tires to chock. Probably gives you more room underneath as well and I believe they were fairly cheap when I bought mine. Just a though for anyone who likes to work underneath there car. If you figure you would need two any way to do the front end work, it only leaves you buying one extra set.

Just did a CVT fluid drain and fill on my 2003 MO. Took just shy of 6 quarts. At 53,000 miles, the fluid in my 1 gallon containers looked like dirty motor oil. Made me cringe... For $135 bucks, it's still cheaper than a new $6000 CVT. Afterwards, CVT dipstick looked much clearer. The dealer here says change it every 60,000 miles. I see why...

Congrats - yeah my CVT fluid didn't look too hot after even 30,000 miles. I am glad I changed it.

The look of the fluid does not mean much.

However, I still would drain-and-fill it every 30k miles. It is a cheap insurance......I did it with the FX as well. Money well spent.

I know Joe will not agree with us but....
