Brand new OEM Gen1 CVT are out of production for the Juke as we now know.
Reman are available but I have zero info on what they actually include but I won't install one without a teardown/rebuild.
The Altima 2007-2012 CVT transmission which is technically the CVT2 architecture for what I'm about to describe is mostly compatible with the Juke Gen 1 transmission in terms of internal components. I've already proven this by retrofitting a few of those refurb CVT2 parts into my Juke CVT rebuild/upgrade......they fit without modification.
These transmission parts are kind of spread across the Jeep, Mitsubishi, Altima, & Juke as they share the same CVT2 architecture and haven't changed much
from 2007 thru 2014 if at all when I did a detailed inspection analysis but aside from date codes the differences were extremely minor.
The following CVT parts are available brand new from Nissan for the JF011E:
Primary pulley variator) (2007-2012 Altima) (31210-1XF0B): $349.58
Secondary Pulley variator (2007-2012 Altima) (31247-1XZ0A): $387.16
Bosch 901083/901066 pushbelt (2007-2012 Altima) (31240-1XF0B): $176.78
Valvebody (Juke 2010-2014) (31705-1XZ2C): $798.02
New oil pump (Juke +2010) (Jatco # JF011-29-7): $306
Torque Converter: $1330
etc.....etc....
Putting this into perspective, buying the CVT pushbelt from Nissan vs. Bosch dealers/distributors would save me $700 vs. buying it aftermarket ($177 vs $857) and reduce the cost of a potential rebuild price by a huge amount. This is really a big deal as prices on everything have gone thru the roof and parts availability hasn't gotten any better for these transmission. The torque converter are available from CVC reman to factory new condition for $136 vs. $1330 new from Nissan. That makes the cost of a rebuild extremely reasonable again with much lower risk than using all used parts.
I'll have to confirm by trying to order the pulley sets as I might actually try them out in the future.
Summarizing, it would be possible to basically piece together an effectively new transmission + heavily upgraded for a moderate amount of money.
I put some numbers together for what rebuild/upgrade would cost and it's now looking reasonable actually.
