Quick Answer

The 2013 JX35 and many 2014–2020 QX60 models use a CVT, as do second-generation QX50 and QX55 models with the VC-Turbo powertrain. Q50 and Q60 cars use conventional automatic transmissions, and later QX60 generations moved to a conventional automatic. Always confirm the exact year, engine, drivetrain, and VIN before service.

Why Does Transmission Identification Matter?

A continuously variable transmission changes ratio through a pulley-and-chain or belt system rather than fixed forward gears. It uses specific fluid and service procedures. A conventional automatic uses stepped gear ratios and can require a different fluid, level-setting method, and diagnostic strategy.

Using the wrong fluid or assuming a CVT symptom applies to a conventional automatic can cause damage or misdiagnosis. The model badge alone is not enough because Infiniti changed transmissions between generations.

Which JX35 and QX60 Models Use a CVT?

The 2013 JX35 and the first-generation QX60 are the Infiniti vehicles most closely associated with the V6 CVT. Published Infiniti service information covers CVT judder and related codes on specified vehicles within that generation.

The redesigned QX60 introduced for 2022 uses a conventional multi-speed automatic rather than the earlier CVT. Later powertrain changes do not turn it back into the same first-generation CVT application. Verify any year gaps and exact equipment by VIN.

Do the QX50 and QX55 Use a CVT?

The second-generation QX50 introduced for 2019 pairs its VC-Turbo engine with a continuously variable transmission. The related QX55 also uses a CVT. Earlier EX/QX50 models used different powertrains and conventional automatics.

That generation split matters when researching fluid, shudder, or used-vehicle concerns. “QX50 transmission” can describe two very different designs depending on the year.

Which Infiniti Models Use Conventional Automatics?

Q50 and Q60 sport sedans and coupes use conventional stepped automatics rather than a CVT. QX80 models also use conventional automatics, with transmission design changing across generations. Many earlier G, M, FX, EX, Q70, and QX70 vehicles likewise use conventional automatics.

This is a planning overview, not a substitute for VIN-based service information. Hybrids, market differences, and mid-generation powertrain changes can alter the exact specification.

How Does Normal CVT Operation Feel?

A CVT can hold engine speed while road speed rises instead of producing the distinct upshifts of a stepped automatic. That behavior can feel unfamiliar without being a defect.

Repeated shudder, slipping, delayed engagement, abnormal noise, overheating warnings, or stored ratio and judder codes are not normal characteristics. A road test should distinguish expected ratio behavior from an actual fault.

Infiniti Transmission Identification and Service Near Metro Atlanta

Fastlane identifies the transmission by VIN and services Infiniti vehicles in Hiram, Smyrna, and Woodstock. Bring prior invoices when available because a replacement unit or previous repair can affect the fluid, software, and next diagnostic step.
