ST 12060

[Plawan]

Off my Moms Chevy Spark. She only drove like 1k miles in a year.
It sorta feels wrong changing it cuz the oil and filter are like new. She has a warranty though so gotta do the mileage or go by time for record keeping.
Passed the light test and was solidly constructed. ADBV was fine and held all the oil in till I cut it. No ripples on the leaf spring and it sealed well.

What year spark and mileage. If it has the 4 speed aisin it's worth keeping. If it's the jatco cvt change the fluid with ns-3 and let it go when worthwhile.

Good looking Super Tech. Good notes & yeah, not much can happen in 1k. ha! Understandable on the warranty.

Yeah it’s the jatco. 2018.
She’s 76 and drives so little I don’t think I’ll need to change the fluid and filters in the cvt for quite a while. Not my favourite choice of cars she could have picked but it is what it is.

Thank you for the C&P

Jatco gets a lot of hate, a lot of their early CVT designs were horrible.

But I have seen plenty of Jatco CVT transmissions that have been maintained with well over 200,000 miles (many of them Sparks), often times the ones that are failing have 100,000-150,000 miles and never been serviced.

Stick with 30k service intervals avoid that 100,000 mile interval or lifetime fluid bs.

Even with religious maintenance like the one in my daughters mitsu they can still suddenly fail and I know the same happens with regular automatics but it seems to be a more frequent occurrence with jatcos and cvt rebuild shops are almost nonexistent as I've read parts are almost impossible to come by.

I changed it a few thousand miles ago and I'm wondering about changing it even more frequently at 10k just to do the most I can. I pulled the pan for the first time and there wasn't much metal in the magnets after over 93k miles as I did do many spills on it and changed the paper filter before which helped so at least that. The metal filter in the pan is just a pickup tube with a mesh so I wasn't in a rush to change it and it was clean with no visible debris. Still I wouldn't be surprised if it just randomly lets go.

Well they certainly are no Toyota/Aisin CVT which are better built but its just like the GM side of things a lot of people hate on the 4L60E obviously not a CVT but they give it the nickname 4L-Slippy but a lot of them are just poorly maintained and there is a lot of well maintained examples with even over 300,000 miles but is a 4L60E as good as a Toyota/Aisin A750E for example? no.

10k intervals on a CVT is a good bit overkill in my opinion.
