Common Transmission Problems

The transmission is an integral part of any vehicle, including the 2015 Infiniti Q70. It is responsible for transferring power from the engine to the wheels, allowing the vehicle to move. However, like any mechanical component, the transmission is prone to problems. In this article, we will discuss some common transmission problems that 2015 Infiniti Q70 owners might encounter.

Transmission Slipping

One of the most common transmission problems experienced by drivers is transmission slipping. This occurs when the transmission fails to maintain a consistent power delivery to the wheels. As a result, there may be a noticeable loss of acceleration or a sudden drop in RPM without a corresponding change in speed. Transmission slipping can be caused by various issues, such as worn out clutch plates, low transmission fluid levels, or a faulty torque converter.

Delayed Engagement

Delayed engagement is another common transmission problem that 2015 Infiniti Q70 owners may experience. This occurs when the transmission takes a few seconds to engage after shifting into drive or reverse. It can be frustrating and potentially dangerous, especially when trying to quickly accelerate or park. Delayed engagement can be caused by low fluid levels, a faulty transmission pump, or worn out clutch plates.

Hard Shifting

If you notice that your 2015 Infiniti Q70’s transmission is shifting gears with a noticeable jolt or jerk, it may be experiencing hard shifting. This can occur when there is a problem with the transmission’s hydraulic system or the electronic controls that regulate gear changes. Hard shifting can also be caused by low transmission fluid levels or worn out clutch plates.

Transmission Overheating

Transmission overheating is a serious problem that can lead to significant damage if left unaddressed. Signs of transmission overheating include a burning smell, fluid leaks, or warning lights on the dashboard. Overheating can occur due to a variety of reasons, such as a malfunctioning cooling system, a clogged radiator, or towing heavy loads without proper cooling precautions.

Symptoms of Transmission Problems

It is essential to be aware of the symptoms that may indicate a transmission problem in your 2015 Infiniti Q70. Identifying these symptoms early can help prevent further damage and costly repairs. Here are some common symptoms to look out for:

Dashboard Warning Lights

If you notice any warning lights, such as the check engine light or the transmission overheat light, illuminated on your dashboard, it is a clear indication that something is wrong with your transmission. These lights are designed to alert you to potential issues and should not be ignored.

Gear Shifting Issues

If you experience difficulty shifting gears or notice the transmission hesitating or slipping between gears, it is likely a sign of transmission trouble. This can manifest as a delay in acceleration or a sudden loss of power.

Burning Smell

If you detect a burning smell coming from your vehicle, particularly when you are running the air conditioning or after extended periods of driving, it could be an indication of transmission problems. This smell is often caused by overheating transmission fluid or a malfunctioning transmission component.

Fluid Leaks

Fluid leaks can signify several issues, including worn out gaskets, seals, or damaged transmission lines. If you notice reddish fluid pooling under your vehicle, it is crucial to address the issue promptly to prevent further damage to the transmission.

Causes of Transmission Problems

Understanding the underlying causes of transmission problems can help you prevent them from occurring or worsening. Here are some common causes of transmission issues in the 2015 Infiniti Q70:

Fluid Leakage

One of the primary causes of transmission problems is fluid leakage. Low transmission fluid levels can lead to decreased lubrication and increased friction within the transmission components, resulting in premature wear and failure.

Clutch Problems

The clutch is a crucial component of the transmission system that allows for smooth gear shifting. If the clutch plates become worn out or damaged, it can cause slipping, hard shifting, and other transmission issues.

Faulty Solenoids

Solenoids are electronically controlled valves responsible for regulating fluid flow within the transmission. When solenoids malfunction, it can lead to problems with gear shifting, delayed engagement, or transmission slipping.

Damaged Valve Body

The valve body is the control center of the transmission, responsible for directing fluid flow and regulating gear changes. If the valve body becomes damaged or clogged, it can result in hard shifting, delayed engagement, or other transmission problems.

Transmission Repair Options

When faced with transmission problems in your 2015 Infiniti Q70, you have several repair options. The specific repair needed will depend on the nature and extent of the issue. Here are some common transmission repair options:

Transmission Fluid Flush

If the transmission problem is caused by contaminated or deteriorated fluid, a transmission fluid flush may be recommended. This involves draining the old fluid, flushing the system with new fluid, and replacing the filter.

Clutch Replacement

If the clutch plates are worn out or damaged, a clutch replacement may be necessary. This involves removing the transmission, disassembling it, and replacing the worn out or damaged clutch plates.

Solenoid Repair

If the transmission problem is caused by faulty solenoids, repairing or replacing the affected solenoids may be necessary. This can often be done without removing the entire transmission.

Valve Body Replacement

If the valve body is damaged or clogged, it may need to be replaced. This is a more involved repair that requires removing the transmission and replacing the valve body.

Common DIY Fixes for Transmission Problems

While some transmission problems require professional expertise, there are some DIY fixes you can try before seeking professional help. Here are a few common DIY fixes for transmission problems:

Checking Fluid Levels

Regularly checking and maintaining proper fluid levels can help prevent transmission problems. Refer to your vehicle’s owner’s manual for instructions on how to check the transmission fluid level and add fluid if necessary.

Replacing Transmission Filter

A clogged or dirty transmission filter can restrict fluid flow and lead to transmission problems. By replacing the filter regularly, you can help ensure proper fluid flow and prevent damage to the transmission.

Inspecting and Adjusting Cables

The cables connecting the transmission to the shifter can become loose or misaligned over time. Inspecting and adjusting these cables can help improve gear shifting and prevent shifting issues.

Cleaning Solenoids

If your transmission problem is caused by dirty or clogged solenoids, cleaning them may help restore proper function. Remove the solenoids, clean them with a suitable cleaner, and reinstall them.

When to Seek Professional Help

While DIY fixes can be effective for some transmission problems, there are instances when it is best to seek professional help. Here are some situations when you should consider consulting a professional:

Persistent Issues after DIY Fixes

If you have attempted DIY fixes but are still experiencing persistent transmission problems, it may be time to seek professional assistance. A professional technician can diagnose the underlying issue and provide the necessary repairs.

Major Transmission Failure

In the case of major transmission failure, such as a complete loss of power or severe internal damage, professional help is essential. Major transmission repairs will require specialized tools and expertise to ensure proper and reliable repairs.

Unusual Noises

Unusual noises coming from the transmission, such as grinding, whining, or clunking sounds, should not be ignored. These can be indications of serious transmission problems that require professional attention.

Check Engine Light

If the check engine light is illuminated, it is a clear indication that there is a problem with your vehicle’s system, including the transmission. A professional technician can use diagnostic tools to identify the specific issue and recommend the appropriate repairs.
