FCA has a deal with Jatco (transmission builder) not to repair, only replace. Nissan may be willing and able to do a rebuild for you since Nissan uses the same unit. Actually the CVT is fairly simple device -- so simple that there is little to rebuild.I have a 2012 jeep patriot so the warranty is long gone lol. Also most workshops get goosebumps when I asked if they can rebuilt my CVT transmission. I assume its because CVT transmissions are a pain to rebuilt
I had a transmission fail in an Oldsmobile and my dealer said he could rebuild or replace for about the same price. The big difference was labor. A rebuild would take about a week; a replacement about a day.
