Whether you are a seasoned mechanic or an amateur DIY enthusiast, this guide will equip you with the knowledge needed to diagnose and fix this pesky problem once and for all. The common causes and diagnostic processes for these problems are discussed.

1. Low Transmission Fluid

While driving a Chevy Silverado and suddenly the P0711 code flashes on the dashboard, there’s a high chance that you’re dealing with low transmission fluid. Low transmission fluid could result in slower shifting, harsh gear engagement, or even complete transmission failure if left untreated. It’s crucial to address this problem promptly before it causes further damage.

Low transmission fluid can cause mechanical issues, decrease fuel efficiency, and increase the risk of overheating. Insufficient lubrication can lead to increased friction and reduced fuel efficiency. Timely action to replenish fluid can prevent costly repairs.


To detect low transmission fluid in a Chevy Silverado: 

  • Regularly check fluid level using a dipstick or fluid level indicator.
  • Inspect the vehicle for leaks and repair if found.
  • Add appropriate transmission fluid if the level is low.
  • Check for overheating and ensure the cooling system is working properly.
  • Performing regular maintenance and changing the fluid at recommended intervals helps maintain the transmission’s longevity and efficiency, and avoid costly repairs.

2. Damaged Wire

The P0711 Chevy Silverado can also be caused by a damaged wire. Wiring issues can occur over time due to wear and tear or rodent damage. Detecting the damaged wire can be challenging, but careful inspection can reveal signs of damage such as fraying or exposed wires. Once located, the wire needs to be repaired or replaced. It’s essential to consider simpler causes like a damaged wire when troubleshooting automotive issues. By addressing these problems promptly, time and money can be saved in the diagnostic process. Don’t overlook wiring problems, as they could be the solution to error codes like P0711.


The P0711 Chevy Silverado indicates a transmission fluid temperature sensor issue. Damaged wires can cause:

  • False readings and trigger the error code.
  • Inspect and repair/replace damaged wires.
  • It may require the disassembly of transmission components.
  • Seek professional assistance (if needed).
  • Promptly addressing the issue can prevent further damage and expensive repairs.

3. Dirty Transmission Fluid

The P0711 Chevy Silverado can be a source of frustration for any truck owner. It is usually triggered by dirty transmission fluid, causing the transmission to operate improperly. While it may seem like a minor issue, dirty transmission fluid can actually lead to significant damage down the line if left unaddressed.

The main reason that dirty transmission fluid triggers the P0711 code is that it hampers the efficiency of the pressure control solenoid. This solenoid regulates hydraulic pressure inside the transmission, ensuring smooth gear shifts. When contaminants build up in the fluid, they can clog or block these solenoids, causing them to malfunction and trigger diagnostic trouble codes (DTCs) like P0711.


  • Regularly changing transmission fluid is important for the truck’s health.
  • Flushing old fluid and replacing it can resolve the error code.
  • Automatic transmission fluid needs to be changed every 80,000 miles while Manual transmission fluid needs to be changed every 50,000 miles.
  • Inspecting and replacing the transmission filter can prevent future complications
  • Addressing warning signs promptly saves time and money.
  • Changing the fluid is necessary before it causes damage to the transmission.

By sticking to manufacturer-recommended service intervals and replacing old fluid with fresh clean lubricant, you can help extend the life of your trucks’ transmission system while avoiding costly repairs down the road. Remember: prevention is always better than cure!

4. Faulty Transmission Fluid Temperature Sensor

The P0711 error code is a common and frustrating problem that Chevy Silverado owners often face. This error code indicates a fault in the transmission fluid temperature sensor. A faulty sensor can lead to improper shifting, overheating of the transmission, and potentially serious damage if left unresolved.

Regularly checking and maintaining transmission fluid levels can prevent faulty temperature sensor issues. External factors can also cause false codes, so a professional diagnosis is important.


  • Diagnose faulty TFT sensor with OBD-II scanner.
  • Resetting the fault code by disconnecting and reconnecting the truck’s battery.
  • Replacing the faulty sensor with technical know-how and basic tools.
  • Upgrading to a higher-quality sensor for a more permanent fix.
  • Consulting a professional for expert guidance and repairs to ensure the truck remains in good condition.

5. Defective PCM

A faulty PCM (Powertrain Control Module) can cause rough shifting in the automatic transmission. It is responsible for controlling various aspects of the engine and transmission performance, including pressure control solenoids. If the PCM in your Silverado is faulty, it can disrupt the communication between the transmission system and the engine, leading to error code P0711. Water damage can lead to code P0711. This code indicates a problem with the transmission fluid temperature sensor circuit. 

A defective PCM can result in poor shifting quality, delayed gear engagement, or even complete transmission failure. It’s essential to address this issue promptly to avoid further damage to your vehicle. While a defective PCM might not be extremely common, it is still worth considering as a possible cause when troubleshooting transmission problems in your Chevy Silverado.


Seek assistance from a professional auto mechanic to fix the issue with your car. Technicians can use specialized equipment to identify the cause of PCM defect.

  • Updating/reprogramming PCM software may fix the problem.
  • If not, replacing the faulty module may be necessary
  • Don’t ignore or delay repairs.
