2014 Chevy Silverado Parts And Accessories

So, you're having some trouble with your 2014 Chevy Silverado? Don't worry, you're not alone. The 2014 Silverado is a great truck, but like any vehicle, it has its common issues and parts that wear out over time. As a service advisor for many years, I've seen it all, and I'm here to help you diagnose and potentially fix some of these problems. We'll also touch on some popular accessories that can improve your truck's functionality and appearance.

Common 2014 Silverado Problems & Solutions

1. Transmission Issues (Specifically the 6L80 Transmission)

The 6L80 automatic transmission is a known weak point in some 2014 Silverados, especially those with higher mileage or that have been used for heavy towing. Owners often report hard shifting, slipping gears, or even complete transmission failure.

Diagnosis: First, check your transmission fluid level. Low or dirty fluid can exacerbate these issues. A simple dipstick check (refer to your owner's manual for the location and procedure) can give you a quick indication. Pay attention to the color and smell of the fluid; it should be reddish-pink and not burnt.

Solution:

• Fluid Change/Flush: Start with a transmission fluid change or flush. This is the least expensive option and can sometimes resolve minor issues. Be sure to use the correct type of fluid as specified in your owner's manual. A drain and fill can cost around $150-$300 at a shop, while a full flush can run $200-$400.
• Valve Body Issues: If the fluid change doesn't resolve the problem, the valve body might be the culprit. The valve body controls the flow of fluid within the transmission, and if it's malfunctioning, it can cause shifting problems. Replacing the valve body can cost between $500 and $1000, depending on the shop's labor rates and whether you opt for a new or remanufactured unit.
• Complete Transmission Rebuild or Replacement: In the worst-case scenario, the transmission might need a complete rebuild or replacement. This is the most expensive option, with rebuilds typically costing between $2500 and $4500, and replacement costing $3500 to $6000, or even more if you choose a performance transmission. Getting multiple quotes is highly recommended.

Preventative Maintenance: Regular transmission fluid changes (every 30,000-50,000 miles, depending on your driving habits) can help prolong the life of your 6L80 transmission. Avoid heavy towing if possible, or consider adding an aftermarket transmission cooler if you frequently tow.

2. AFM (Active Fuel Management) Problems

The AFM system, designed to improve fuel economy by deactivating four of the engine's cylinders, is another common source of trouble in the 2014 Silverado. Many owners experience oil consumption issues, leading to fouled spark plugs and potential engine damage.

Diagnosis: Keep an eye on your oil level. If you find yourself frequently adding oil between changes, AFM might be the culprit. Misfires, indicated by a flashing check engine light, are another common symptom.

Solution:

• AFM Disabler: An AFM disabler plugs into your OBD-II port and prevents the AFM system from engaging. This can eliminate oil consumption and misfire issues. These devices typically cost between $150 and $300.
• AFM Delete Kit: A more permanent solution is to install an AFM delete kit. This involves removing the AFM components and replacing them with standard, non-AFM parts. This is a more involved process and typically requires professional installation. Expect to pay between $1500 and $3000 for parts and labor.

Important Note: Deactivating or deleting the AFM system may void your warranty, so check with your dealership before proceeding.

3. Electrical Issues

Electrical gremlins can plague any vehicle, and the 2014 Silverado is no exception. Common problems include malfunctioning power windows, door locks, and infotainment systems.

Diagnosis: Use a multimeter to check for voltage at the affected components. A faulty fuse is often the simplest explanation.

Solution:

• Check Fuses and Relays: This is the first and easiest step. Consult your owner's manual to locate the fuse box and identify the fuse or relay associated with the malfunctioning component. Replacing a fuse is a cheap and easy fix.
• Wiring Harness Inspection: Inspect the wiring harness for any signs of damage, such as frayed wires or loose connections. Repair or replace damaged wiring as needed.
• Body Control Module (BCM) Issues: If the problem persists, the BCM might be faulty. The BCM controls many of the vehicle's electrical functions. Replacing the BCM can be expensive, typically costing between $500 and $1000, including programming.

4. Rust Issues

Depending on where you live, rust can be a significant concern for 2014 Silverado owners, particularly around the wheel wells and rocker panels.

Diagnosis: Visually inspect your truck for any signs of rust, especially in areas prone to moisture and road salt exposure.

Solution:

• Rust Repair: For minor surface rust, you can sand it down and apply a rust inhibitor and touch-up paint. For more extensive rust, you might need to have the affected area professionally repaired or replaced. This can range from a few hundred dollars to several thousand, depending on the severity of the damage.
• Rust Prevention: Apply a rust preventative coating to the undercarriage and other vulnerable areas. This can help protect your truck from future rust damage. Undercoating services typically cost between $100 and $300.

Popular 2014 Silverado Accessories

Now, let's talk about some accessories that can enhance your 2014 Silverado:

1. Bed Covers

A bed cover can protect your cargo from the elements and improve your truck's fuel economy. There are many different types of bed covers available, including tonneau covers (soft or hard), rolling covers, and folding covers. Prices range from $300 to $1500, depending on the type and quality.

2. Floor Mats and Liners

Protect your truck's interior with durable floor mats or liners. WeatherTech and Husky Liners are popular brands known for their high-quality, custom-fit products. Expect to pay between $100 and $300 for a set of floor mats or liners.

3. Nerf Bars or Running Boards

Nerf bars or running boards make it easier to get in and out of your truck, especially if it's lifted. They also add a touch of style. Prices range from $200 to $600, depending on the style and material.

4. Performance Exhaust System

A performance exhaust system can improve your truck's horsepower and torque, as well as give it a more aggressive sound. Magnaflow and Flowmaster are popular brands. Expect to pay between $500 and $1500 for a cat-back exhaust system, plus installation.

5. Towing Accessories

If you frequently tow with your Silverado, consider investing in towing accessories such as a weight distribution hitch, trailer brake controller, and tow mirrors. These accessories can improve your safety and make towing easier. Prices vary widely depending on the specific accessories you need.

Final Thoughts: Taking care of your 2014 Chevy Silverado involves addressing potential issues proactively and choosing the right accessories to enhance its functionality. Remember to consult your owner's manual for specific maintenance recommendations and always consult with a qualified mechanic for any complex repairs. Good luck, and happy trucking!
