    I just read through the CVT portion of the service manual and never saw anything explaining the removal and replacement of the filter?!?

    You guys really think 190k miles on a highway cars trans is Good? I think that's not that good at all. Especially at 4k a pop.

    200k on any original transmission is good.. and to put a $4k transmission in a used 200k car would be a silly choice, esp when low mileage cvts are going for 1/10 that cost.

    Yes. The days of the Chrysler Torqueflite and the Ford C6 are over...and have been for a long time. The very conventional 3-speed slushboxes in the old Geo Metros were good for about half that.

    Any guess as to what provided the shavings?

    Yes. For a manual gearbox no

    Only an idiot would drop 4k on a new one.

    I also follow Toyota Tundra news as I have one and there is a million mile Tundra that was used as a hotshot delivery truck for the oil business. Used to haul and tow daily. The original automatic lasted until 770k miles when reverse went out.
    Tons of other tundra and Tacomas with 3-500k stock engines and transmissions.

    I also used to be into panther platform cars and those went well over 300k on the transmissions. Even in taxi and livery use.

    If it was almost all city miles I'd say it was decent for an economy car but for easy hwy miles 190k doesn't seen great.

    But this is a cvt which I personally wouldn't trust over an automatic. At least not until they are more proven. I remember when Nissan started using them first in all their stuff and they were always having issues.

    I did too. The woman in the mitsubishi parts department didn't know either and basically said they come with the transmission. Finally she asked one of their own techs if they had a filter and he had to show her where they are..... They had none in stock only a few in Canada I believe. I tried to get an acdelco one for a spark to try and there were none in Canada and only a few in the USA.

    I never said it was great. But remember this is 10k econo car not a 60k toyota truck. That's kind of a ridiculous comparison. And for never having the transmission filter changed ever 190k isn't too bad. I'm curious if the tundra still has the original filter in the tranny or would it crap out at 200k as well if maintained the same?
    But we are expecting these to be lasting twice that. I'm hoping that if I change the filters once in a while along with all the extra fluid that pours out when the pan is pulled that the cvt should last much longer. Changing 2-3 quarts of fluid once in a while doesn't seem to do prevent failure as I'm pretty sure the case would be for most other transmissions.
    I'll be pulling the pans on a few other car's once I get the filters and gaskets and I'll post what I find.

    My tundra Was no where close to 60k but I understand what you're saying. Toyota uses a sealed trans. Saying the fluid is good for life (BS) I will eventually pump out the old and pump in new but not for a very long time.

    Yeah I would bet if you swapped out the fluid it would have prolonged the life of that cvt. Keep us all posted as I think I speak for everyone, we all enjoy hearing about the fleet you maintain!!
