P0730 on Nissan vehicles indicates incorrect gear ratio. Au7o has documented this code across 13 Nissan models — most commonly on 370Z, Altima, GT-R. This code means the transmission computer detected that the actual gear ratio (calculated from input vs. output shaft speeds) does not match what it should be for the commanded gear. In other words, the transmission isn't delivering the correct gear, which often shows up as slipping, flaring RPM during shifts, or being stuck in the wrong gear. It can stem from internal mechanical wear, low or contaminated fluid, or faulty solenoids and sensors. The vehicle may shift harshly or enter limp mode. Typical repair costs on Nissan range from $150 to $20,000, depending on the specific model and root cause.

Common Causes of P0730

  • •Low or contaminated transmission fluid
  • •Worn clutches or bands (internal slipping)
  • •Faulty shift solenoids
  • •Dirty or sticking valve body
  • •Faulty input or output speed sensor
  • •Internal hydraulic/line pressure problems
  • •Torque converter problems
  • •General high-mileage transmission wear

P0730 on Nissan by Model

Nissan 370Z(1 issue)

  • Manual Transmission Synchro Wear (2nd/3rd)2009-2020

    The CD009 6-speed manual transmission can develop synchro wear, particularly affecting 2nd and 3rd gears. This results in grinding when shifting, especially under aggressive driving. The synchros are brass and wear faster than some competitors.

Nissan Altima(1 issue)

  • CVT Transmission Failure/Shudder2013-2023

    The CVT transmission is known for reliability issues including shuddering, jerking, and complete failure. Nissan extended the CVT warranty on some model years to 10 years/120,000 miles due to widespread problems. High-mileage CVTs are particularly at risk.

Nissan GT-R(1 issue)

  • GR6 Dual-Clutch Transmission Judder and Failure2009-2024

    The Nissan GT-R GR6 dual-clutch transmission (built by BorgWarner) develops judder during low-speed maneuvers, parking, and first gear takeoffs. The clutch packs wear unevenly, and the transmission control module software can cause harsh engagement. Track use accelerates wear dramatically. Nissan extended the transmission warranty on early models. Replacement costs are exceptionally high.

Nissan Juke(1 issue)

  • CVT Transmission Failure (Jatco CVT7)2011-2017

    The Juke CVT (Jatco CVT7/JF015E) paired with the turbocharged engine is stressed beyond its design capacity. The turbo's torque output accelerates CVT wear, leading to shuddering, slipping, and failure often before 100,000 miles. AWD models add additional strain on the CVT.

Nissan Kicks(2 issues)

  • CVT Overheating During Highway Driving2018-2024

    The Nissan Kicks CVT transmission (Jatco CVT7 W/R) overheats during sustained highway driving, particularly in hot weather or hilly terrain. The transmission enters limp mode to protect itself, limiting speed to 40-50 mph. The small displacement 1.6L engine forces the CVT to work harder at highway speeds, contributing to heat buildup.

  • Excessive Engine Noise and Vibration (HR16DE)2018-2024

    The Kicks HR16DE 1.6L engine produces excessive noise and vibration that transmits into the cabin, particularly at highway RPMs where the CVT holds the engine at 3,000-4,000 RPM. The lack of sound insulation and the CVT's tendency to keep RPMs high under load amplifies the issue.

Nissan Maxima(1 issue)

  • CVT Transmission Shudder and Failure (Jatco CVT8)2016-2023

    The 2016-2023 Maxima (8th generation) uses the Jatco CVT8 paired with the VQ35DE engine. Despite being a flagship sedan, the CVT suffers from shuddering, hesitation, and premature failure. The high torque output of the 3.5L V6 exacerbates CVT wear. Nissan TSB NTB16-076 addresses CVT judder for these models.

Nissan Murano(1 issue)

  • CVT Transmission Failure and Shudder2009-2020

    The 2009-2020 Murano equipped with the CVT (Jatco JF010E and later JF016E) is prone to premature failure. Symptoms include shuddering, slipping, and complete loss of drive. The 2009-2014 models with JF010E are particularly problematic. Nissan extended CVT warranties on some model years but many owners face failures outside coverage.

Nissan Pathfinder(2 issues)

  • CVT Transmission Failure (Jatco CVT8/JF016E)2013-2020

    The 2013-2020 Pathfinder uses the Jatco CVT8 (JF016E) which suffers from premature failure under the heavier loads of the SUV. The transmission overheats during towing, climbing, or sustained highway driving. Nissan issued TSB NTB15-024 for CVT judder and extended the warranty under CSI P8242. A class-action settlement provided additional coverage for some owners.

  • 9-Speed Automatic Harsh Shifting, Shift Shock, and Delayed Engagement2022-2025

    The redesigned 2022+ Pathfinder switched from the CVT to a ZF-based 9-speed automatic, and many owners reported harsh 1-2 or 2-3 shifts, lurching at low speed, hesitation when selecting Drive or Reverse, and occasional banging into gear. Nissan issued service information and software updates addressing shift quality and transmission control behavior, indicating this is a recognized field issue rather than isolated driver perception. Complaints commonly describe the problem as most noticeable when cold, in stop-and-go traffic, or during parking maneuvers.

Nissan Quest(1 issue)

  • CVT Transmission Failure Under Load2011-2017

    The Quest CVT (Jatco JF010E/RE0F09B) paired with the VQ35DE V6 suffers from premature failure, particularly when the vehicle is fully loaded with passengers and cargo. The combination of a heavy minivan with a CVT designed for lighter vehicles leads to overheating and accelerated wear. Failures commonly occur between 60,000-120,000 miles.

Nissan Rogue(1 issue)

  • CVT Transmission Failure/Shudder2014-2020

    The Nissan Rogue's CVT transmission is prone to premature failure, shuddering, and jerky operation. Nissan extended the CVT warranty on many affected vehicles to 10 years/120,000 miles due to widespread issues. High-mileage CVTs are particularly at risk for complete failure.

Nissan Rogue Sport(1 issue)

  • CVT Transmission Shudder and Premature Failure2017-2022

    The Nissan Rogue Sport uses the same Jatco CVT (Continuously Variable Transmission) that has been problematic across the Nissan lineup. The CVT can develop shuddering during acceleration, hesitation, and in severe cases, complete failure. The belt and pulley system wears prematurely, and the transmission fluid degrades faster than Nissan service intervals account for. Nissan extended the CVT warranty to 10 years/120,000 miles for some model years due to the widespread nature of this issue.

Nissan Sentra(1 issue)

  • CVT Transmission Failure (Jatco CVT7/JF015E)2013-2021

    The 2013-2021 Sentra uses the Jatco CVT7 (JF015E) transmission which is prone to premature failure, shuddering, and overheating. Nissan extended the CVT warranty to 10 years/120,000 miles under Customer Service Initiative P8242. The transmission can fail as early as 60,000 miles. Common failure modes include belt slipping, valve body failure, and bearing wear.

Nissan Versa(1 issue)

  • CVT Transmission Failure (Jatco CVT7/JF015E)2012-2021

    The 2012-2021 Versa CVT (Jatco JF015E) is one of the most failure-prone transmissions in Nissan's lineup. The combination of a budget vehicle with heavy use leads to premature CVT failure, often before 100,000 miles. Nissan extended the CVT warranty on 2012-2017 models to 10 years/120,000 miles due to a class-action settlement (Batista v. Nissan).
