Nissan's CVT history is more complicated than most technicians realize, and the confusion between CVT generations costs shops time and customers money when the wrong fluid or the wrong service procedure is applied. Let me break down the key generational differences and why they matter for what you do on the bench. Nissan used CVT units supplied primarily by Jatco, which is a transmission supplier that Nissan owns a significant stake in. The early Jatco CVT generations — commonly referred to as the CVT1, CVT2, and CVT7 in technical literature — are what most shops encounter in Altimas, Sentras, and Muranos from the 2000s through the early 2010s. These units use a push steel belt and a conventional electro-hydraulic control system. Fluid spec for these generations is typically NS-2, and the failure mode profile is the belt-and-pulley wear pattern we've discussed in previous emails.
