You took a chance losing $800 by tearing apart. I for one really appreciate that. It's was interesting to see what failed and why. Well done Ivan. See you again on part two.

I actually worked on a product design team on an early prototype metal belt CVT back in the mid-80s. I worked on the electronics and software but new the basics of the mechanical and hydraulic systems. If the belt has seen that kind of damage, the sheaves are likely scored. Tolerances between the sheaves and the little metal wedges that make up the push belt are CRITICAL. Likely the sheaves would have to be replaced.

Nissan Just authized us techs to pull apart the CVTs and replace belt/chain Assemblies under certain failure conditions for the Altima and Pathfinder I believe and this was only about 2 months ago...

I called it! In the Part 2 removal vid. Was second guessing myself after someone reminded me that you had lost oil pressure, but the oil pump must drive off the secondary. Having owned snowmobiles and atvs with a much simpler system, the mode of failure sounded exactly the same - no sound, just an instant neutral.

Ivan, you're the most brilliant mechanic I've seen. It sucks you're not in my state. Pennsylvania is lucky to have someone as good as you.

Yes we pull them apart and rebuild. And fluid change 30 or 40 thou is important

Nissan should walk away from cvt transmissions and use regular 6 speed automatic or 8 speed auto
