Infiniti Transmissions We Cover

Real Infiniti transmissions from our warehouse, tested and ready to ship. A single model year can ship with more than one transmission, so match by transmission code rather than by vehicle — text us your VIN and we will confirm it.

7-Speed Automatic (RE7R01A)

G37, G25, Q50, Q60, Q70, M37, M56, EX37, QX70, FX37, FX50 (2009+). Our deepest Infiniti line — the Jatco seven-speed behind the VQ37VHR and VQ25, listed by RWD or AWD and by the mid-year VIN breaks Infiniti built into the Q50 and Q60.

5-Speed Automatic (RE5R05A)

G35, FX35, FX45, M35, M45, EX35, Q45 (2002–2008), G37 (2008). The five-speed of the VQ35DE and VQ35HR era — the sedan and coupe units differ, the AWD unit carries the transfer output, and the 2008 G35 is listed by its VQ35HR engine.

Q50 / Q60 3.0T (VR30DDTT) 7-Speed

Q50 and Q60 3.0t and Red Sport 400 (2016+). The seven-speed behind the twin-turbo V6 — listed by 300 HP or 400 HP, RWD or AWD, and by the 2019 build-date split (thru 11/30/18 and from 12/01/18), because the calibrations do not interchange.

QX56 / QX80 Automatics (4x2 and 4x4)

QX56 (2004–2013), QX80 (2014+). The full-size SUV units behind the VK56 V8 — the five-speed through 2010 and the seven-speed from 2011, listed by 4x2 or 4x4 because the 4x4 unit carries the transfer-case output.

Jatco CVT (JX35, QX60, QX50)

JX35 (2013), QX60 (2014–2020), QX50 (2019+). The transverse CVTs — the QX60 unit behind the VQ35DE and the QX50 unit behind the VC-Turbo are different transaxles, and the 2021-on QX60 moved to a nine-speed automatic.

6-Speed Manual (FS6R31A)

G35 (2003–2007), G37 (2008–2013), Q60 (2014–2015), and the G20 five-speed (1991–2002). The rear-drive six-speed shared with the 350Z and 370Z — the G37 unit with the revised synchros differs from the G35 unit, and both are listed by year.

G20 4-Speed Automatic / 5-Speed Manual

G20 (1991–1996, 1999–2002). The front-drive Sentra-derived transaxles behind the SR20DE — automatic and manual listed separately, and the P10 and P11 generations do not share a unit.

Q45 / J30 / I30 / QX4 4-Speed Automatics (1990s)

Q45 (1991–2001), J30 (1993–1997), I30 and I35 (1996–2004), QX4 (1997–2003). The first-generation Infiniti automatics — the rear-drive Q45 and J30 units, the front-drive I30 transaxle, and the QX4 unit with its 4x4 transfer output, listed by year.

FX / EX / QX70 AWD and RWD

FX35, FX45, FX37, FX50 (2003–2013), EX35, EX37 (2008–2013), QX70 (2014–2017). The crossover units — every listing says 4x2 (RWD) or 4x4 (AWD), and the EX and FX carry mid-year VIN breaks (thru 2/08, from 3/08) that the listings quote.

Why Buy a Used Infiniti Transmission from Auto Power Source

Infiniti builds on Nissan hardware, and the same family name covers units that do not swap — the RE7R01A seven-speed is a different calibration behind the VQ37VHR, the VR30DDTT at 300 HP and the VR30DDTT at 400 HP, the five-speed of the G35 sedan is not the coupe unit, and every AWD Infiniti transmission carries a transfer output the RWD unit lacks. Every product on this page is titled by model, drivetrain and the mid-year VIN break where Infiniti made one. Our 484 verified Infiniti transmissions cover the whole run: the seven-speed in the G37, Q50, Q60, Q70, M and QX70, the five-speed in the G35, FX, M35, M45 and EX35, the Q50 and Q60 3.0t units by output, the QX56 and QX80 units by 4x2 and 4x4, the CVTs in the JX35, QX60 and QX50, the six-speed manuals of the G35, G37 and Q60, and the 1990s Q45, J30, I30, G20 and QX4 automatics.

Every Infiniti transmission we sell has been pulled from a low-mileage donor vehicle, cataloged by VIN, and held in our climate-controlled warehouse pending sale. Each unit goes through our six-step inspection — VIN-matching against the donor and against your vehicle, Shift-Testing through every gear under load, noise verification, full visual inspection of case, pan and bellhousing, multi-angle photography for your approval, and palletized freight. Seven-speed units get a valve-body and solenoid check under load, CVT units get a belt and pulley inspection, and AWD units have the transfer output inspected. Rejected units never reach the buyer.

You pay a fraction of dealer-new pricing for the same Infiniti engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and have 30 days from delivery to return for any reason — no restocking fees. The warranty printed on the listing — with extended coverage up to 3 years available — covers you if anything goes wrong after install. Across 100K+ engines and transmissions in stock, we hold a 0% fitment-related return rate.
