Symptoms of Transmission Problems

Slipping Gears

One of the most common signs of transmission problems is when your Suburban’s gears start slipping. This means that your vehicle might unexpectedly shift gears while driving, causing a loss of power or a sudden drop in RPMs. If you notice your engine revving higher than usual without gaining speed, it’s likely that your gears are slipping.

Delayed Shifting

Another symptom of transmission problems is delayed shifting. You may experience a noticeable delay when shifting gears, especially when moving from park to drive or reverse. This delay can cause the engine to rev higher, making it difficult to control the vehicle’s speed and acceleration.

Erratic Shifting

If you notice your Suburban shifting gears in an inconsistent or unpredictable manner, it could be a sign of transmission problems. Erratic shifting often results in jerky movements or sudden acceleration or deceleration. This can make driving hazardous and should be addressed immediately.

Burning Smell

A burning smell coming from your transmission is a clear indicator that something is wrong. This smell is usually caused by overheating transmission fluid or a failing clutch. Ignoring this symptom can lead to more severe transmission damage and should be addressed promptly.

Leaking Fluid

Transmission fluid is essential for the proper functioning of your Suburban’s transmission. If you notice reddish fluid pooling underneath your vehicle or find low fluid levels, it’s a sign of a transmission fluid leak. Leaking fluid can lead to a lack of lubrication, resulting in excessive heat and wear on the transmission components.

Causes of Transmission Problems


One of the leading causes of transmission problems in the 2013 Suburban is overheating. Operating your vehicle under extreme conditions, such as towing heavy loads or driving in hot climates, can cause the transmission to overheat. This can lead to fluid breakdown, component damage, and ultimately, transmission failure.

Lack of Maintenance

A lack of maintenance can also contribute to transmission problems. Regularly servicing your Suburban, including fluid changes and filter replacements, is crucial to keep your transmission functioning properly. Neglecting routine maintenance can result in dirty or degraded fluid, which can lead to shifting issues, slipping gears, and other transmission problems.

Fluid Contamination

Contaminated transmission fluid is another common cause of transmission problems. Dirt, debris, and particles can find their way into the transmission system, causing blockages and impairing the transmission’s ability to operate smoothly. Regular fluid changes and using high-quality transmission fluid can help prevent fluid contamination.

Worn Clutch

The clutch is an essential component of a manual transmission system. Over time, the clutch can wear out due to normal use, resulting in slipping gears, grinding noises, and difficulty shifting. Regularly checking and maintaining the clutch can help extend its lifespan and prevent transmission problems.

Valve Body Issues

The valve body is responsible for controlling the flow of transmission fluid and directing the appropriate gears. If the valve body becomes damaged or faulty, it can cause issues with shifting, resulting in erratic or delayed gear changes. Replacing or repairing the valve body is necessary to restore proper transmission function.

Diagnosing Transmission Problems

When you experience transmission problems in your 2013 Suburban, it’s essential to correctly diagnose the issue before proceeding with any repairs. Here are some common methods used to diagnose transmission problems:

Warning Lights

The Suburban is equipped with a check engine light and a transmission warning light. If either of these lights illuminates, it indicates a potential problem with your transmission. It’s crucial to have the vehicle’s onboard computer system scanned to retrieve any error codes that can help identify the specific issue.

Fluid Inspection

Inspecting the transmission fluid can provide valuable insights into the condition of your Suburban’s transmission. Healthy transmission fluid should be a clear, reddish color and have a slightly sweet smell. If the fluid appears dirty, has a burnt smell, or contains metal particles, it indicates transmission problems.

Computer Diagnostic

Modern vehicles, including the 2013 Suburban, have sophisticated computer systems that can be used to diagnose transmission problems. The vehicle’s computer can be connected to a diagnostic tool that reads and interprets error codes, providing detailed information about the specific issue affecting the transmission.

Test Drive

Taking your Suburban for a test drive can help identify any noticeable symptoms of transmission problems. Pay attention to how the transmission shifts, if there are any unusual noises or vibrations, and if you experience any difficulty engaging or disengaging gears. This information can assist a technician in diagnosing the problem accurately.

Transmission Pan Inspection

Removing the transmission pan and inspecting the contents can reveal valuable information about any internal issues within the transmission. Metal shavings, excessive debris, or a burnt smell in the pan can indicate serious problems that require further investigation and repairs.

Repairing Transmission Problems

Once the cause of the transmission problem has been determined, there are several repair options available. The appropriate repair method will depend on the specific issue. Here are some common repair options for transmission problems:

Transmission Flush

A transmission flush involves removing and replacing all the transmission fluid. This procedure helps remove any contaminants, such as debris or metal shavings, that may be causing transmission problems. Flushing the transmission and replacing it with fresh, high-quality fluid can help restore proper transmission function.

Replacing Solenoids

Solenoids are responsible for controlling the flow of transmission fluid. If a solenoid fails, the transmission can experience shifting issues or fail to shift at all. Replacing the faulty solenoid(s) can resolve the problem and restore proper transmission functionality.

Clutch Replacement

If the clutch is worn out or damaged, it may need to be replaced. Replacing the clutch involves removing the transmission and replacing the worn or damaged component. This repair ensures smooth and efficient gear engagement and prevents slipping or grinding gears.

Transmission Overhaul

In severe cases, a transmission overhaul may be necessary. This involves disassembling the transmission, replacing worn or damaged components, and reassembling it to like-new condition. A transmission overhaul is a more extensive and expensive repair option but is often the only solution for severe or irreparable transmission problems.

Torque Converter Replacement

The torque converter is responsible for transmitting the engine’s power to the transmission. If the torque converter fails, it can lead to slipping gears, shuddering, or complete transmission failure. Replacing the faulty torque converter can resolve these issues and restore proper transmission function.
