The 2017 Honda Pilot, while generally a reliable family SUV, has unfortunately become associated with a specific gremlin: transmission troubles. Many owners have reported experiencing rough shifting, shuddering, and even complete transmission failure, turning what should be a smooth ride into a frustrating and potentially expensive ordeal. Understanding the nature of this problem, its potential causes, and how to address it can save you time, money, and a whole lot of stress.

What Exactly is Going On With These Pilots?

The main culprit behind the 2017 Honda Pilot transmission woes is often the ZF 9-speed automatic transmission. While ZF makes excellent transmissions, its implementation in the 2016-2017 Pilots (and some other Honda models) had some teething issues. The most common symptoms owners report include:

  • Rough Shifting: Jerky or abrupt gear changes, especially between lower gears. This can feel like the car is "bucking" or hesitating.

  • Shuddering: A vibration or shaking sensation, often felt at lower speeds or when accelerating gently. This is sometimes described as feeling like driving over rumble strips.

  • Hesitation: A delay in acceleration when pressing the gas pedal, particularly when trying to merge onto a highway or pass another vehicle.

  • Transmission Slipping: The engine revs up without a corresponding increase in speed, indicating that the transmission is not properly engaging the gears.

  • Error Codes: The check engine light may illuminate, accompanied by diagnostic trouble codes (DTCs) related to the transmission. Common codes include P0741 (Torque Converter Clutch Circuit Performance or Stuck Off), P0777 (Pressure Control Solenoid "B" Performance or Stuck On), and P0729 (Gear 6 Incorrect Ratio).

  • Complete Transmission Failure: In the worst-case scenario, the transmission can completely fail, rendering the vehicle undrivable.

Why is This Happening? Digging Into the Root Causes

Several factors are believed to contribute to the 2017 Pilot transmission problems:

  1. Software Glitches: The transmission control module (TCM) software is responsible for managing the shifting behavior of the transmission. Early versions of the software had glitches that could lead to rough shifting and premature wear. Honda has released software updates (TSBs) to address these issues.

  2. Torque Converter Issues: The torque converter is a fluid coupling that transmits power from the engine to the transmission. Some owners have reported problems with the torque converter, leading to shuddering and other transmission issues.

  3. Valve Body Problems: The valve body is a complex hydraulic control unit that regulates the flow of transmission fluid to different parts of the transmission. Malfunctions in the valve body can cause shifting problems and other issues.

  4. Fluid Degradation: Transmission fluid lubricates and cools the internal components of the transmission. Over time, the fluid can degrade, losing its lubricating properties and becoming contaminated with debris. This can lead to increased wear and tear on the transmission.

  5. Manufacturing Defects: It's possible that some transmissions were manufactured with defects that contributed to their premature failure.

Is There Anything Honda Has Done About It? (TSBs and Recalls)

Honda has issued several Technical Service Bulletins (TSBs) to address the 2017 Pilot transmission problems. A TSB is a notification to dealerships about common issues and recommended repair procedures. Here are a few key TSBs to be aware of:

  • TSB 17-040: Addresses shuddering issues related to the torque converter. This TSB typically involves a transmission fluid flush and a software update.

  • TSB 17-041: Addresses rough shifting and hesitation issues. This TSB typically involves a software update to the TCM.

  • TSB 18-132: An updated version of TSB 17-040, further refining the torque converter shuddering fix.

Important Note: TSBs are not recalls. A recall is issued when a safety defect is identified, and the manufacturer is required to repair the vehicle free of charge. TSBs, on the other hand, are more like recommendations for repair procedures. While Honda dealerships will often perform TSB-related repairs under warranty, they are not obligated to do so if the vehicle is out of warranty.

How to Check for TSBs: You can check for TSBs related to your 2017 Honda Pilot by:

  • Visiting the National Highway Traffic Safety Administration (NHTSA) website: www.nhtsa.gov
  • Contacting your local Honda dealership.

What Can You Do if You're Experiencing These Problems? (Troubleshooting and Solutions)

If you're experiencing transmission problems with your 2017 Honda Pilot, here's a step-by-step approach to take:

  1. Document the Symptoms: Keep a detailed record of the symptoms you're experiencing, including when they occur, how often they occur, and any other relevant information. This will be helpful for the technician diagnosing the problem.

  2. Check the Transmission Fluid: Inspect the transmission fluid level and condition. Low fluid level or dark, dirty fluid can indicate a problem.

    • Refer to your owner's manual for the proper procedure for checking the transmission fluid.

  3. Check for Error Codes: Use an OBD-II scanner to check for any diagnostic trouble codes (DTCs) related to the transmission. This can provide valuable clues about the nature of the problem.

  4. Consult a Qualified Technician: Take your vehicle to a qualified mechanic or Honda dealership for a diagnosis. Be sure to provide them with the detailed record of your symptoms and any error codes you found.

  5. Inquire About TSBs: Ask the technician if there are any relevant TSBs that apply to your vehicle. If so, discuss whether performing the TSB-recommended repairs is appropriate.

  6. Consider a Transmission Fluid Flush: If the transmission fluid is dirty or degraded, a transmission fluid flush may help to improve shifting performance. Important: Make sure the technician uses the correct type of transmission fluid specified for your vehicle.

  7. Software Update: Ensure your Pilot's TCM has the latest software update installed. This can often resolve shifting issues and improve overall transmission performance.

  8. Valve Body Replacement: If the valve body is identified as the source of the problem, replacing it may be necessary.

  9. Torque Converter Replacement: If the torque converter is faulty, replacing it may be required.

  10. Transmission Replacement or Rebuild: In severe cases, the transmission may need to be replaced or rebuilt. This is a more expensive option, but it may be necessary if the transmission is severely damaged.

Preventing Future Transmission Problems: Proactive Maintenance

While the 2017 Pilot transmission issues can be frustrating, there are steps you can take to help prevent future problems:

  • Regular Transmission Fluid Changes: Follow the recommended maintenance schedule for transmission fluid changes. This will help to keep the fluid clean and prevent it from degrading. Honda recommends changing the transmission fluid every 30,000 miles under severe driving conditions (towing, frequent stop-and-go traffic). Under normal driving conditions, extending to 60,000 miles is generally acceptable.

  • Avoid Aggressive Driving: Avoid aggressive acceleration and hard braking, as this can put unnecessary stress on the transmission.

  • Proper Towing Practices: If you tow with your Pilot, be sure to follow the manufacturer's recommendations for towing capacity and towing speed.

  • Address Issues Promptly: If you notice any signs of transmission problems, such as rough shifting or shuddering, take your vehicle to a qualified mechanic for diagnosis and repair as soon as possible.
