Common Transmission Problems in Chevy Silverado

There are several transmission issues that have been reported by Chevy Silverado owners over the years. Some of the most common problems include:

  1. Erratic shifting and hard shifts: Silverado owners have reported experiencing harsh or rough shifting between gears, as well as sudden jerking when accelerating.
  2. Transmission fluid leaks: Leaking transmission fluid can lead to a variety of problems, including low or burnt transmission fluid, which can cause damage to the vehicle’s transmission system.
  3. Clunking noise when shifting gears: A clunking noise when shifting between gears may indicate a problem with the transmission system.
  4. Jerking: The transmission system may cause the vehicle to jerk, leading to discomfort for the passengers.
  5. Manufacturing defects: Some Silverado models have been reported to have manufacturing defects that can lead to transmission issues.

Models Affected by Transmission Issues

The Chevy Silverado 1500 models from 2012 to 2019 have been reported to have the most common transmission problems. These issues include high fuel consumption, selector switch failure, and transmission issues that can occur after crossing a million miles.

Transmission Problems in Specific Silverado Models

Various Silverado models have different transmission issues. Here is a breakdown of some specific models and the problems they face:

Chevy Silverado 1500 with 4L60E / 4L65E Transmission (Most Early Models 2011-Down)

  1. Faulty 1-2 Accumulator: A delay or harshness during the 1-2 shift may be due to a faulty 4L60E 1-2 accumulator.
  2. 3-4 Clutch Failure: The total loss of 3rd and 4th gears may be caused by premature wear of the 3-4 clutch pack.

Chevy Silverado 1500 with 4L80E Transmission (1500 HD Only)

  1. Failed Shift Solenoids: Shift solenoids control the hydraulic shifting systems, and if they fail, the vehicle may experience slipping between gears, failure to shift, or a failure to shift into overdrive.
  2. Overheating: Towing heavy loads or constant shifting in stop-and-go traffic can cause the transmission to overheat, potentially leading to blown seals and damage to clutches, bands, and the valve body.

Chevy Silverado 1500 with 6L80 Transmission (Most Late Models 2007+)

  1. Pressure Regulator System: Problems with the 6L80 pressure regulator system can lead to harsh shifts, soft shifts, failure to engage Drive, slipping in-and-out of gear, and overheating.

Causes of Silverado Transmission Problems

The common transmission problems in the Chevy Silverado can be linked to different reasons, including:

  1. Transmission Control Module (TMC) Failure: The TMC sends signals from sensors in different parts of the vehicle to the transmission. A malfunctioning TMC can lead to transmission problems.
  2. Torque Converter Failure: A deteriorating torque converter can lead to transmission fluid spillage and eventually the failure of the transmission system.

Technical Service Bulletins (TSBs) and Recalls

Over the years, Chevrolet has issued several Technical Service Bulletins (TSBs) and recalls to address transmission problems in the Silverado. Some of the most notable TSBs and recalls include:

  1. TSB 01-07-30-023B: This TSB addresses harsh 1-2 upshifts with a failed transmission system in various Chevy Silverado models.
  2. NHTSA Recall 14V152000: This recall was issued for 2014 Silverado 1500 models with a transmission oil cooler line that is not securely seated in the fitting, posing a risk of transmission fluid leaks and vehicle fires.

Preventive Measures and Maintenance

Proper maintenance of your Chevy Silverado’s transmission is crucial in preventing transmission problems. Some preventive measures and maintenance tips include:

  1. Regularly check and replace transmission fluid as needed.
  2. Inspect transmission cooler lines for leaks or damage.
  3. Install an auxiliary transmission cooler to prevent overheating.
  4. Schedule regular transmission inspections with a certified mechanic.

Addressing Transmission Issues

If you experience any transmission issues with your Chevy Silverado, it is essential to address them promptly to avoid further damage to your vehicle. Some recommended steps to take include:

  1. Consult a certified mechanic to diagnose and repair the problem.
  2. Consider replacing the transmission system if necessary.
  3. Research any TSBs or recalls related to your specific Silverado model and have the necessary repairs made.
  4. Regularly perform preventive maintenance to minimize the risk of transmission problems.

What’s the worst year for Chevy 1500?

The worst year for the Chevy Silverado 1500 is the 2014 model due to various problems such as faulty A/C unit, stalling while driving, heavy oil consumption, electrical issues, and transmission problems.

Other years to avoid are 2005, 2008, 2015, and 2016. It is recommended to purchase the most reliable year models that include the first, second, and fourth generations, the 2020 model, and 2003 for its design, 2006 for its ruggedness, 2009 for its engine power, and 2012 for its reliability.

Has Chevy fixed the transmission problems?

There have been ongoing transmission problems reported by drivers of Chevy Silverado 1500 models, particularly those built between 2015 and March 1, 2019.

General Motors has reportedly released technical service bulletins and made attempts to fix the issue, including replacing the transmission control module and reprogramming the software starting in 2023. However, there is no clear indication of whether these efforts have fully resolved the transmission issue.

It is important to note that limp mode, which may cause the vehicle to operate differently, is a safety feature designed to alert the driver to a potential problem with the transmission, rather than an indication of the need for a new transmission.

If you are considering purchasing a Chevy 1500, it is recommended that you research the reliability and common problems of each model year, and consider purchasing the most reliable year models.

How long will a Chevy transmission last?

The lifespan of a Chevy transmission depends on various factors, including the model, maintenance, and driving habits. Generally, a well-maintained Chevy transmission can last up to 150,000 miles or more.

However, there have been ongoing issues with transmission problems in Chevy Silverado year models 2015-2017. It is unclear if Chevy has fully resolved these problems.

It is advisable to research the reliability and common problems of each model year before purchasing a Chevy truck or SUV. Regular maintenance, such as changing the transmission fluid every 45,000 miles, is crucial to extending the lifespan of your Chevy transmission

Why are transmissions so expensive to replace?

Transmissions can be expensive to replace due to their complex design and the cost of labor involved in removing and replacing the transmission.

Additionally, the cost of the replacement parts can be quite high. Therefore, regular maintenance is crucial to extending the lifespan of a transmission and avoiding costly repairs.

For example, changing the transmission fluid every 30,000-40,000 miles and upgrading to synthetic fluid can help prevent common transmission problems and resist heat and oxidation.

Finding a quality repair shop and servicing the transmission every 30,000 miles can also enhance its performance and prolong its life.

Is it cheaper to buy a new transmission or rebuild?

It depends on various factors such as the make and model of your vehicle, the extent of the damage to your transmission, and the cost of labor.

A transmission rebuild is a cost-effective option that utilizes newer gaskets and seals while retaining optimal performance for your specific vehicle.

On average, a remanufactured transmission can cost between $1,300 and $3,400, depending on the make and model of your vehicle, while the cost of a rebuilt transmission can range from $1,500 to $3,500.

However, a new transmission can cost significantly more than both of these options. In addition, regular maintenance is crucial to extending the lifespan of transmission and avoiding costly repairs, no matter which option you choose.


While the Chevy Silverado is a reliable and high-performing pickup truck, it is not immune to transmission issues.

By being aware of common transmission problems and their causes, as well as performing regular maintenance, Silverado owners can minimize the risk of experiencing these issues.

If you encounter any transmission problems with your Silverado, consult a certified mechanic to diagnose and repair the problem promptly.
