    This is what it'd look like if there actually was an interchange and they had a proper interchange.Name:  screencapture-car-part-cgi-bin-search-cgi-2019-01-30-07_21_15.png

Size:  62.7 KB I worked with the exact interchange system for 14 years. Car-part is just a website so public joe blow can look up stuff online rather than calling around. They use the eden/hollander system for the interchange.

    Hope I don't come across as too much of a dink but that could screw a lot of people if they don't know how to properly use that site.

    I stole this from http://car-part.com/buyerfaq.htm


    Why am I asked to choose a year range?

    If the part you are searching for does not have interchange, you will be asked if you want to search for your exact model or search for parts in similar models. At this stage you must also specify a year range. The year range default will be only the year you searched for. If you know that another model year will also fit your needs, you can expand the year range search. Prior to buying your part, you may want to contact the recycler to verify this is the correct part for your vehicle.



    How will I know which year range to search?

    You may have personal knowledge of which parts will work for you, you may have a crash guide (such as Mitchell or Motor), or you may have an interchange manual (Hollander® or Mitchell) that contains the year and the range interchangeability. Car-Part.com has interchangeability built into the search engine using Hollander Interchange®.

    Yes, I've been quite good about it. As Fummins has given evidence of at various times, these CVTs just don't last much past 275,000kms. I think the longest lasting on record was the one that blew at 309,000. Unless anyone has a Mirage with more on the original CVT?

    Ok. So you can only drain 3 quarts from the pan, but you can add all you need (7ish quarts) through the dipstick tube?

    Out of curiosity, did you change the cvt fluid at the specified intervals prior to it failing? No judgment, just trying to get a handle on why these jatco 7 go south.

    If the trans is completely empty, then yes, 7 through the dipstick tube. Otherwise you only add what was drained.

    Yes, I was pretty good about all that. I did 2x drain/fill every 50,000kms or so. Didn't swap any filters, however.

    Fummins has mentioned the Thrust Bearing/Washer tends to be the choke point, I believe.

    Thanks, man. Yeah, I've read about the thrust washer. Really does seem like the problem is poor design nissan/jatco cvt's.

    waiting for better weather...

    @Fummins: I haven't sourced one yet, I'm a little reluctant until this weather clears up. My garage isn't heated. Brrr.
