Nissan Sentra CVT is the JF015E β Jatco's smallest and most failure-prone unit. The belt is undersized for urban use. If still within Nissan's extended warranty period (84mo/84k miles on 2013β2017), the dealer repair is free. Outside coverage, we rebuild or replace the JF015E with remanufactured units. Fluid changes every 30,000 miles are essential.
