The 2017 Chevrolet Silverado is an incredible truck, renowned for its strength, durability, and power. However, even the most reliable vehicles can sometimes face transmission issues, which can be incredibly frustrating when they occur. Transmission problems in your Silverado can lead to difficulty driving, poor acceleration, rough shifting, or even complete breakdowns if left unaddressed. But don’t worry; these issues are often manageable with the right steps. In this article, we will discuss how to quickly fix common transmission problems in the 2017 Silverado.
Common Transmission Problems in the 2017 Silverado
Before you can fix your 2017 Silverado's transmission issues, it's important to first understand the problems that could be causing them. Here are some common transmission-related issues that Silverado owners often face:
Rough Shifting
One of the most common transmission problems is rough shifting. This happens when your truck has difficulty changing gears, causing jerky or hard shifts. It can occur if the transmission fluid is low, dirty, or if the shift solenoids are faulty.
Delayed Shifting
Delayed shifting happens when there's a noticeable delay between pressing the accelerator and the truck shifting into the correct gear. This issue can be caused by old or contaminated transmission fluid, faulty sensors, or issues with the transmission control module (TCM).
Transmission Slipping
Transmission slipping occurs when the engine revs, but the truck doesn't accelerate as expected. This is often due to low fluid, worn gears, or malfunctioning sensors.
Grinding or Clunking Noises
Unusual sounds like grinding or clunking from the transmission area typically point to internal damage. This can be caused by worn gears or other mechanical failures.
Overheating
Transmission overheating can be caused by low fluid levels or a malfunctioning cooling system, and it can lead to serious damage if not addressed quickly.
Check Engine Light
If you see the "Check Engine" light on, it could indicate a problem with the transmission system. Transmission-related issues often trigger this warning light.
Understanding these issues is the first step in resolving your transmission problems. Now, let’s discuss how you can fix these problems.
Step-by-Step Guide to Fixing 2017 Silverado Transmission Problems
1. Check and Top Off Transmission Fluid
Transmission fluid is essential to keeping your vehicle's transmission system running smoothly. Low or dirty fluid can cause rough shifting, slipping, and overheating. Therefore, the first step in fixing your Silverado's transmission issues is to check and top off the fluid.
How to Check and Top Off Transmission Fluid:
- Locate the Dipstick: In the 2017 Silverado, the transmission dipstick is usually located near the engine, marked with a brightly colored handle (typically yellow or red). Some models may have a sealed transmission system that doesn't have a dipstick, requiring professional inspection.
- Check Fluid Level: With the engine running and the truck in "Park," remove the dipstick, wipe it clean, and then insert it back into the tube. Pull it out again to check the fluid level, which should fall within the marked range.
- Inspect Fluid Quality: Healthy transmission fluid is red and slightly sweet-smelling. If the fluid is brown or smells burnt, it's a sign that it needs to be replaced.
- Add Fluid if Necessary: If the fluid level is low, use the appropriate type of fluid recommended for your Silverado (refer to your owner's manual). Add small amounts of fluid at a time and recheck the level to avoid overfilling.
If the fluid is in good condition and at the right level but the problem persists, further steps are necessary.
2. Inspect and Replace the Transmission Filter
A clogged or dirty transmission filter can restrict the flow of fluid and cause shifting problems. If your Silverado has high mileage or hasn't had the filter replaced in a while, it's a good idea to check it.
How to Inspect and Replace the Transmission Filter:
- Remove the Transmission Pan: To access the filter, you will likely need to remove the transmission pan. This will require lifting the truck and draining the fluid.
- Inspect the Filter: Check the filter for any visible clogs or debris. A filter that looks dirty or worn out should be replaced.
- Replace the Filter: Purchase a replacement filter that matches your Silverado's specifications. Install it carefully, making sure the new filter is properly seated. Also, replace the gasket for the transmission pan before reattaching it.
3. Reset the Transmission Control Module (TCM)
The Transmission Control Module (TCM) is responsible for regulating shifting and adapting the transmission’s performance based on driving conditions. If the TCM has lost calibration or is malfunctioning, it could cause issues like delayed or rough shifting.
How to Reset the TCM:
- Disconnect the Battery: To reset the TCM, first, disconnect the negative terminal of the truck's battery.
- Wait for 15 to 30 Minutes: Leave the truck for 15-30 minutes to allow the TCM to reset completely.
- Reconnect the Battery: After waiting, reconnect the battery and start the truck. The TCM should now be reset, and the shifting issues may be resolved.
If resetting the TCM doesn't work, further investigation may be needed.
4. Inspect and Replace the Shift Solenoid
The shift solenoid controls the flow of transmission fluid through the system. A malfunctioning solenoid can cause delayed shifting or rough gear changes, and it may need to be replaced.
How to Inspect and Replace the Shift Solenoid:
- Locate the Shift Solenoid: The shift solenoid is typically located inside the transmission, requiring you to remove the transmission pan to access it.
- Test the Solenoid: Use a multimeter to test the solenoid for electrical continuity. If it's not functioning properly, it may need to be replaced.
- Install a New Solenoid: Purchase a replacement solenoid that fits your 2017 Silverado. Carefully install the new solenoid and ensure all connections are secure before reassembling the transmission pan.
5. Check for Transmission Leaks
Leaking transmission fluid can cause low fluid levels, which in turn leads to shifting problems and overheating. If your Silverado is leaking transmission fluid, it's essential to identify and fix the source of the leak.
How to Check for Transmission Leaks:
- Inspect the Transmission Area: Look for signs of transmission fluid around the transmission or under the truck. Wet spots or puddles of red or pink fluid are a clear indication of a leak.
- Check the Seals and Gaskets: The seals and gaskets around the transmission pan and input/output shafts are common areas for leaks. If you find any damaged or worn seals, they should be replaced.
- Repair the Leak: Replacing damaged seals or gaskets is usually a straightforward task, but if the leak is more serious, you may need professional help to repair it.
6. Consult a Professional Mechanic
If you've tried all the above steps and your transmission problems persist, it may be time to consult a professional mechanic. Transmission issues can sometimes be caused by deeper, more complex mechanical or electrical failures that require specialized knowledge and tools to fix.
A mechanic will be able to run diagnostics, pinpoint the exact issue, and recommend a solution, whether that means replacing internal transmission components or even rebuilding the entire transmission.
I Hope This Helps You Fix Your 2017 Silverado Transmission Problems. Transmission issues in the 2017 Silverado can be frustrating, but with the right knowledge, you can often fix them quickly and easily. Regularly maintaining your transmission by checking fluid levels, replacing the filter, and addressing minor issues as they arise can help keep your truck running smoothly. If the problems persist, don't hesitate to take your Silverado to a trusted professional for further assistance.
