The 2019 Chevy Traverse, marketed as a family-friendly SUV, has unfortunately faced its share of transmission troubles, leaving many owners frustrated and searching for answers. These issues range from rough shifting and slipping gears to more serious problems that can compromise the vehicle's safety and reliability. Understanding the common transmission problems experienced by 2019 Traverse owners, knowing the potential causes, and exploring available solutions can empower you to navigate these challenges effectively and keep your Traverse on the road.

Uh Oh, My Traverse is Shifting Rough! What's Going On?

One of the most frequent complaints about the 2019 Chevy Traverse transmission revolves around rough or harsh shifting. This manifests as jerky movements between gears, especially during acceleration or deceleration. Sometimes, you might even feel a noticeable "clunk" when the transmission shifts. This isn't just uncomfortable; it can also indicate an underlying problem that needs attention.

Possible Causes:

  • Low or Contaminated Transmission Fluid: Transmission fluid is the lifeblood of your transmission. It lubricates the internal components, cools the system, and helps transmit power. Low fluid levels or contaminated fluid (dirty, burnt, or containing metal particles) can lead to friction, overheating, and rough shifting.

  • Faulty Solenoids: Solenoids are electromagnetic valves that control the flow of transmission fluid to different parts of the transmission. If a solenoid malfunctions, it can disrupt the proper fluid pressure and timing, causing shifting problems.

  • Worn Clutch Packs: Inside the transmission, clutch packs are responsible for engaging and disengaging gears. Over time, these clutch packs can wear down, leading to slippage and rough shifting.

  • Valve Body Issues: The valve body is a complex component that directs transmission fluid to the correct gears. Problems within the valve body, such as stuck valves or damaged passages, can significantly impact shifting performance.

  • Software Glitches: Modern transmissions are controlled by sophisticated computer systems. Software glitches or programming errors can sometimes cause shifting abnormalities.

Slipping Gears? That's Not a Good Sign!

Another common issue plaguing 2019 Traverse owners is transmission slippage. This occurs when the engine revs up without a corresponding increase in speed. It feels like the transmission is struggling to hold the gear, and the vehicle may hesitate or lose power. Slipping gears are a serious problem that can lead to further transmission damage if left unaddressed.

What's Causing the Slip?

  • Worn Clutch Packs (Again!): As mentioned earlier, worn clutch packs are a primary culprit in transmission slippage. When they lose their friction material, they can't effectively engage the gears, resulting in slippage.

  • Low Transmission Fluid Pressure: Insufficient fluid pressure can prevent the clutch packs from engaging properly, leading to slippage. This can be caused by a faulty pump, leaks in the system, or a clogged filter.

  • Torque Converter Problems: The torque converter is responsible for transferring power from the engine to the transmission. If the torque converter malfunctions, it can cause slippage, especially at higher speeds.

  • Internal Leaks: Leaks within the transmission can reduce fluid pressure and cause slippage. These leaks can occur in seals, gaskets, or internal components.

That Annoying Hesitation: Delayed Engagement

Have you noticed a delay when shifting into drive or reverse? This delayed engagement is another symptom of potential transmission problems in the 2019 Chevy Traverse. It can be frustrating and even dangerous, especially when you need to accelerate quickly.

Why is My Traverse Hesitating?

  • Low Transmission Fluid (Surprise!): Once again, low transmission fluid can contribute to delayed engagement. The transmission needs sufficient fluid to build pressure and engage the gears quickly.

  • Valve Body Issues (Round Two): Problems within the valve body can also cause delays in engagement. Stuck valves or damaged passages can prevent the fluid from reaching the correct areas in a timely manner.

  • Worn Seals: Worn or damaged seals can lead to fluid leaks and reduced pressure, resulting in delayed engagement.

  • Internal Damage: In more severe cases, internal damage to the transmission components, such as broken gears or damaged shafts, can cause significant delays in engagement.

The Dreaded "Check Engine" Light and Transmission Codes

The "Check Engine" light is never a welcome sight, and when it's accompanied by transmission-related symptoms, it's a clear indication that something is wrong. A diagnostic scan can reveal specific Diagnostic Trouble Codes (DTCs) that pinpoint the source of the problem.

Common Transmission Codes for the 2019 Traverse:

  • P0700: Transmission Control System Malfunction - This is a general code that indicates a problem within the transmission control system. It often accompanies other more specific codes.

  • P0716: Input/Turbine Speed Sensor "A" Circuit Range/Performance - This code indicates a problem with the input speed sensor, which monitors the speed of the transmission input shaft.

  • P0717: Input/Turbine Speed Sensor "A" Circuit No Signal - This code indicates that the input speed sensor is not sending a signal to the transmission control module.

  • P0729: Gear 6 Incorrect Ratio - This code indicates that the transmission is not shifting into 6th gear properly.

  • P0776: Pressure Control Solenoid "B" Performance or Stuck Off - This code indicates a problem with the pressure control solenoid B, which regulates fluid pressure within the transmission.

  • P0796: Pressure Control Solenoid "C" Performance or Stuck Off - Similar to P0776, this code indicates a problem with pressure control solenoid C.

  • P0842: Transmission Fluid Pressure Sensor/Switch "A" Circuit Low - This code indicates a problem with the transmission fluid pressure sensor.

  • P0872: Transmission Fluid Pressure Sensor/Switch "C" Circuit Low - This code indicates a problem with the transmission fluid pressure sensor C.

Important Note: These are just a few of the common transmission codes associated with the 2019 Chevy Traverse. A proper diagnostic scan is essential to accurately identify the specific problem and determine the appropriate course of action.
