    CVT transmission FLUSH attempt

    So this weekend if I have time I am going to attempt to flush the fluid and change all of the filters (pan and cartridge). I have all of the parts I need. Still haven't got under the hood and figured out how I am going to do it.

    My goal is to mimic a flush machine. I think I'm going to remove the transmission lines going to and coming from the cooler, run the car and let the line coming from the trans drain into a pan and use the line going from the cooler to the trans to refill the trans while this is happening. Not sure how I'm going to do that. Maybe just using a funnel attached to the line and filling as the car runs.

    What's your guys thoughts?

    How do you plan to flush the actual passages? You do know that the lines that come off the cvt cooler are filled with coolant not cvt fluid. When you remove the cooler the passages for the fluid aren't threaded so you'd either have to fab up your own plate with some type of fitting or try to stuff a hose in there and not expect it to hold up very well.

    I personally wouldn't bother. I'd just change the fluid and filters. All the bolts have 10mm heads so that makes it simple.

    Maybe around 125000-150000miles pull the cvt out, split the case and replace the thrust washer on the input shaft as preventative maintenance.

    WOW! That sucks.

    I totally assumed that the car had a transmission oil cooler. With transmission fluid going through it and I was planning on tapping into the lines. Man I am so disappointed right now. Guess if that's true I will just be doing a drain fill and filter replacement.

    Transmission oil does run through the cooler it’s that instead of moving air through the cooler it’s cooled by engine coolant in a stack type cooler. I would think the stack cooler would keep the CVT temps at a more stable temperature (especially at low speeds) since coolant is always pumping through it.

    So I'm attempting to drain the transmission and replace the filters but it looks like the O-ring that came with the parts is too big.
