2018 Infiniti Q50 3.0t 7-Speed Automatic Transmission | JR710E | VR30DDTT | 69k Miles | OEM RWD/AWD | Tested

This is a used OEM JR710E 7-speed automatic transmission pulled from a 2018 Infiniti Q50 3.0t equipped with the VR30DDTT twin-turbo V6, and it’s the exact Jatco-built 7AT that Infiniti used across the Q50 and Q60 3.0t lineup from 2016-2022, so it’s a direct replacement for any RWD or AWD Q50 3.0t that needs a gearbox, and with only 69k miles it’s well below the average lifespan for these units when maintained, and the JR710E is a major evolution over the old RE5R05A 5AT with two extra gears, faster shift logic, and much higher torque capacity specifically designed for the 300hp/295tq and 400hp/350tq VR30 variants, and the gear ratios are 4.783 1st, 3.103 2nd, 1.984 3rd, 1.371 4th, 1.000 5th, 0.871 6th, and 0.776 7th, which keeps the VR30 in boost and gives the Q50 aggressive acceleration plus sub-2000rpm cruise at 120km/h for quiet highway driving, and the transmission uses full electronic control with an integrated TCM mounted on the valve body, adaptive learning, and rev-matched downshifts in manual mode, and the torque converter has a multi-plate lockup clutch that engages as early as 2nd gear to reduce heat and improve throttle response, and the case is VR30-specific with the correct bellhousing pattern, starter location, and input shaft for the 3.0t, so it bolts straight to any 2016-2022 Q50/Q60 VR30 without adapters, and the output configuration matches RWD or AWD depending on the donor car, with AWD units including the transfer case mount, and the JR710E is known to handle full bolt-on and tuned VR30 power reliably, with stock transmissions living at 500-550whp when trans temps are managed and Nissan Matic S or equivalent LV fluid is serviced every 40-50k miles, and this 69k mile unit was road-tested for shift quality, lockup engagement, and limp-mode codes before removal, with no slipping, flaring, or harsh 2-3/3-4 shifts that sometimes show up on neglected units, and it includes the torque converter, valve body, and TCM, so your Q50’s ECU will recognize it after a basic TCM relearn, and it uses the factory cooler lines and 36-spline output for RWD or front driveshaft flange for AWD, and if your Q50 3.0t is stuck in fail-safe, slipping under boost, or has the common valve body pressure solenoid codes P0744/P17F0, replacing the whole unit with a low-mile tested gearbox is faster and more reliable than rebuilding, and this JR710E gives you back factory smooth shifts, manual mode paddle control, and the strength Infiniti built into the VR30 platform for daily driving and tuned street performance without going to a built Level 10 or Pure Drivetrain unit yet.
