FAQ About Infiniti CVT Transmissions
Are Infiniti CVTs reliable?
Modern CVTs, including those from JATCO, are generally reliable when properly maintained. Regular fluid changes are crucial to extending the lifespan of the transmission.
What is the recommended maintenance for an Infiniti CVT?
Infiniti recommends specific CVT fluid change intervals in their owner’s manuals. Following these guidelines is essential. Using the correct CVT fluid is also critical.
Can I modify my Infiniti CVT for better performance?
Modifying a CVT is generally not recommended. It can negatively affect its reliability and void the warranty. Furthermore, CVTs are designed for efficiency and smooth operation, not necessarily high performance.
Where can I find more information about my Infiniti’s transmission?
Consult your Infiniti owner’s manual or contact an authorized Infiniti dealer for specific information about your vehicle’s transmission and recommended maintenance procedures.
Troubleshooting Common Infiniti CVT Issues
While modern CVTs are generally reliable, certain issues can arise. Being aware of these potential problems can help you address them promptly and prevent further damage. Listen for unusual noises like whining or buzzing during acceleration, which could indicate a problem with the CVT’s internal components. Pay attention to any slipping or hesitation during gear changes, as this can signal a loss of hydraulic pressure or belt wear. If you experience any of these symptoms, it’s crucial to have your vehicle inspected by a qualified technician specializing in CVT transmissions.
Preventative Measures for Long-Term CVT Health
The best way to avoid CVT issues is through proactive maintenance. Stick to the recommended CVT fluid change intervals outlined in your owner’s manual. Using the correct type of CVT fluid is also essential, as using the wrong fluid can damage the transmission. Avoid aggressive driving habits, such as frequent hard acceleration and sudden stops, as these can put excessive strain on the CVT. Regular inspections by a qualified technician can also help identify potential problems early on, allowing you to address them before they escalate into more significant repairs.
Understanding Infiniti’s CVT Warranty
Familiarize yourself with the terms of your Infiniti’s warranty regarding the CVT transmission. Understand the duration of the warranty and what types of repairs are covered. Keep accurate records of all maintenance performed on your vehicle, as this may be required to validate warranty claims. In the event of a CVT failure, contact your Infiniti dealer promptly to discuss your warranty options and arrange for necessary repairs. Be prepared to provide documentation of your vehicle’s maintenance history to support your claim.
When to Seek Professional Help
While some minor CVT issues can be addressed with simple maintenance, more complex problems require the expertise of a qualified technician. If you experience any significant drivability issues, such as severe slipping, jerking, or complete loss of power, do not attempt to diagnose or repair the problem yourself. Instead, have your vehicle towed to a reputable repair shop specializing in CVT transmissions. A professional technician will have the tools and knowledge necessary to accurately diagnose the problem and perform the necessary repairs.
Making Informed Decisions About CVT Repairs
When faced with a CVT repair, gather as much information as possible before making a decision. Obtain multiple quotes from different repair shops to ensure you’re getting a fair price. Ask the technicians to explain the diagnosis and repair process in detail, and don’t hesitate to ask questions. Consider the cost of repairs versus the cost of replacing the entire transmission. In some cases, replacing the CVT may be a more cost-effective option in the long run. Ultimately, the decision should be based on your budget, the vehicle’s overall condition, and the long-term reliability of the repair.
Resources for Infiniti CVT Owners
Numerous resources are available to help Infiniti CVT owners stay informed and make informed decisions. Consult your owner’s manual for specific information about your vehicle’s transmission and recommended maintenance procedures. Visit the Infiniti website for technical service bulletins and recall information. Online forums and communities dedicated to Infiniti vehicles can provide valuable insights and advice from other owners. Consider subscribing to automotive publications and websites that offer unbiased reviews and comparisons of CVT transmissions. By staying informed and proactive, you can ensure the long-term health and performance of your Infiniti’s CVT transmission.
