Causes Behind Nissan CVT Stuck In Low Gear

Transmission Fluid Issues

  • Low transmission fluid can lead to problems within the CVT. 
  • Inadequate fluid levels may hinder the transmission’s ability to engage higher gears properly, causing it to remain stuck in a lower gear.

Faulty Transmission Solenoids

  • CVTs rely on a series of solenoids to control the flow of transmission fluid and regulate gear changes. 
  • If these solenoids become damaged or fail to function correctly, the CVT may not shift into higher gears as intended, leaving it stuck in a lower gear.

Sensor Malfunctions

  • Modern vehicles, including Nissan, utilize various sensors to monitor engine speed, throttle position, vehicle speed, and other critical parameters. 
  • If any of these sensors provide incorrect or erratic readings, the CVT’s computer may not receive the correct information to initiate gear changes, resulting in a low lock.

CVT Belt or Chain Issues

  • CVTs use a belt or chain to continuously transfer power between different gear ratios. 
  • If this belt or chain becomes worn, damaged, or slips out of place, it can disrupt the transmission’s operation and prevent it from shifting into higher gears.

Mechanical Failures

  • Internal components, such as pulleys or bearings, may experience wear or damage, impeding smooth gear changes.

Electrical Problems

  • The CVT’s control unit relies on an intricate network of electrical connections. If electrical issues, such as short circuits or damaged wiring, the control unit may not receive the proper signals, leading to gear shift problems.


  • CVTs are sensitive to heat, and prolonged exposure to high temperatures can damage the transmission. 
  • Overheating may lead to degraded transmission fluid, warped components, or reduced performance, including getting stuck in low gear.

Various Troubleshooting Steps You Can Take

  • Start by checking the transmission fluid level. Ensure the vehicle is on a level surface and the car is in “Park.” 
  • If you notice a transmission fluid leak, have it repaired immediately and refill the transmission fluid.
  • Try resetting the transmission’s electronic control unit (ECU) by disconnecting the vehicle’s battery for about 30 minutes and reconnecting the battery, and starting the car to see if the issue persists.
  • Inspect the transmission solenoids and sensors to ensure they are functioning correctly. 
  • Have a qualified mechanic inspect the belt or chain and replace it if necessary.
  • Check for any clogs in the transmission cooler or radiator that could hinder the cooling process.
  • Check with a Nissan dealership or authorized service center to see if a software update is available for your vehicle.

FAQs Of Nissan CVT Stuck In Low Gear

Q: Is a Nissan CVT covered under warranty for this issue?

A: Warranty coverage varies depending on the vehicle’s age, mileage, and specific warranty terms. If your Nissan is still within the warranty period, the repairs for a CVT issue might be under coverage.

Q: Is a CVT replacement the only solution for a severely stuck transmission?

A: A CVT replacement might be necessary if the transmission has suffered significant damage.
