Common Transmission Issues in 2009 Infiniti G37

The 2009 Infiniti G37 is known for its luxurious features, powerful engine, and sporty handling. However, like any other vehicle, it is not immune to transmission problems. In this article, we will discuss some of the common transmission issues that you may encounter with your 2009 Infiniti G37 and the steps you can take to identify, address, and prevent these problems from occurring.

Slipping Gears

One of the most common transmission problems in the 2009 Infiniti G37 is slipping gears. This occurs when the transmission fails to properly engage or disengage the gears, resulting in a loss of power and difficulty accelerating. You may notice a sudden drop in RPMs even when you press the gas pedal, or your engine may rev high but your vehicle won’t move as expected.

Delayed Engagement

Delayed engagement is another transmission issue that can occur in the 2009 Infiniti G37. This is when there is a noticeable delay between shifting gears and the transmission actually engaging. You may experience a lag in acceleration or a hesitation when you try to shift from park to drive or reverse.

Transmission Fluid Leaks

Transmission fluid leaks are a common problem in many vehicles, including the 2009 Infiniti G37. Leaks can occur due to worn seals, gaskets, or transmission lines, and they can lead to a loss of fluid, which in turn can cause overheating and damage to the transmission. If you notice red or pink fluid pooling under your vehicle or a burning smell, it’s important to address the issue promptly.

Symptoms of Transmission Problems

Recognizing the symptoms of transmission problems in your 2009 Infiniti G37 can help you take the appropriate steps to address the issue. Here are some common symptoms to look out for:

Jerking or Shuddering

If you experience a jerking or shuddering sensation when accelerating or shifting gears, it may be a sign of transmission problems. This can occur due to worn or damaged components within the transmission system.

Difficulty Shifting Gears

Difficulty shifting gears, such as needing to apply excessive force or experiencing resistance when trying to shift, can indicate transmission problems. This can occur when the transmission is not properly engaging or disengaging the gears.

Strange Noises

Strange noises, such as whining, grinding, or clunking sounds, coming from your transmission can be a cause for concern. These noises can indicate a variety of issues, including worn bearings, damaged gears, or low transmission fluid.

Causes of Transmission Problems

Understanding the common causes of transmission problems in the 2009 Infiniti G37 can help you identify the root of the issue and take appropriate action. Here are some common causes:

Worn Clutch

A worn clutch can cause slipping gears and difficulty shifting in manual transmissions. Over time, the clutch can become worn due to friction and require replacement.

Faulty Solenoids

Solenoids are responsible for regulating the flow of transmission fluid within the system. If a solenoid becomes faulty or fails, it can result in transmission issues such as slipping gears or delayed engagement.

Low Transmission Fluid

Low transmission fluid can cause a variety of transmission problems, including slipping gears, delayed engagement, and overheating. Regularly checking and maintaining the proper level of transmission fluid is crucial to preventing these issues.

Burning Smell

A burning smell emanating from your vehicle, especially when accompanied by slipping gears or fluid leaks, can indicate overheating or burning transmission fluid. This is a clear sign of a significant transmission problem that requires immediate attention.

Complete Transmission Failure

If your 2009 Infiniti G37 experiences a complete transmission failure, you will no longer be able to shift gears or drive the vehicle. You may hear grinding noises, feel a loss of power, or notice a burning smell. In this situation, your transmission will need to be replaced or rebuilt.

Diagnosing Transmission Problems

When you suspect transmission problems in your 2009 Infiniti G37, it is important to properly diagnose the issue before taking any repair or maintenance actions. Here are some diagnostic steps to follow:

Checking Transmission Fluid

One of the first steps in diagnosing transmission problems is checking the level and condition of the transmission fluid. Low or dirty fluid can cause a variety of transmission issues, so make sure to follow your vehicle’s owner’s manual for instructions on how to check and add transmission fluid if necessary.

Performing a Transmission Flush

If your transmission fluid is dirty or contaminated, a transmission flush can help to remove the old fluid and debris from the system. This can be done by a professional mechanic or at a reputable service center.

Scanning for Error Codes

Modern vehicles are equipped with onboard diagnostic systems that can provide valuable information about transmission problems. By using a diagnostic scanner, a mechanic can retrieve error codes stored in the vehicle’s computer and pinpoint the potential issues more accurately.

Common Solutions for Transmission Problems

Once you have diagnosed the transmission problem in your 2009 Infiniti G37, there are several common solutions that can address the issue. Here are three of the most common solutions:

Replacing the Clutch

If a worn clutch is causing transmission problems in your manual transmission vehicle, replacing the clutch assembly may be necessary. This involves removing the transmission, replacing the clutch disc, pressure plate, and release bearing, and reassembling the system.

Repairing or Replacing Solenoids

If faulty solenoids are causing transmission issues, they can often be repaired or replaced. Solenoids are relatively inexpensive parts, but labor costs can vary depending on the vehicle and the accessibility of the solenoids.

Fixing Transmission Fluid Leaks

If your 2009 Infiniti G37 is experiencing transmission fluid leaks, it is crucial to address the source of the leak and repair it promptly. This may involve replacing worn seals or gaskets, repairing damaged transmission lines, or tightening loose fittings.

Replacement Parts

The cost of replacement parts for transmission repairs can vary depending on the specific components that need to be replaced. In general, OEM (Original Equipment Manufacturer) parts tend to be more expensive than aftermarket parts but can offer better quality and reliability.

Additional Expenses

In addition to labor costs and replacement parts, there may be additional expenses such as taxes, shop fees, and the cost of any additional repairs or maintenance needed during the transmission repair process. It is important to discuss these potential expenses with your chosen repair shop before proceeding with the repairs.
