2013-2017 Dodge Viper Flywheel: Diagnosis, Inspection, and Replacement Guide
Learn the symptoms of a failing Gen 5 Viper flywheel, what to inspect on a used unit, and why replacement is almost always better than resurfacing.
- This part is a flywheel, specific to the manual-transmission-only 2013-2017 Gen 5 Viper.
- Do NOT resurface the flywheel; replacement is the recommended procedure to avoid clutch engagement issues.
- Replacement is a major, transmission-out job (5/5 difficulty), so always replace the clutch, pilot bearing, and rear main seal at the same time.
- When buying used, visually inspect the friction surface for heat cracks and the ring gear for damage, and buy from a source that guarantees it is not warped.
Understanding the Flywheel in Your Gen 5 Viper
The 2013-2017 Dodge Viper was exclusively offered with a TREMEC TR6060 six-speed manual transmission. This means the part connecting the engine to the transmission is a flywheel, not a flex plate (which is used in automatic transmissions). This component is fundamental to both starting the engine and putting its massive power to the ground. While generally robust, issues with the flywheel can cause noticeable drivetrain problems. There are no specific recalls or Technical Service Bulletins (TSBs) from Dodge for flywheel-related issues on the Gen 5 Viper, indicating that widespread defects are not a known concern. Failures are typically related to high mileage, aggressive driving, or collateral damage from a failed clutch.
Symptoms of a Failing Flywheel
A bad flywheel can manifest in several ways. Because it's part of the clutch assembly, its symptoms can often be confused with a bad clutch disc or pressure plate.
- Vibrations: A warped or unbalanced flywheel can cause vibrations that are felt through the clutch pedal or the entire car. This is often described as "clutch chatter" and is most noticeable when engaging the clutch from a stop.
- Grinding or Whirring Noises: If the teeth on the starter ring gear are chipped or worn, you may hear a loud grinding or whirring sound when you try to start the engine. In severe cases, the starter may fail to engage the flywheel at all.
- Clutch Slippage: If the flywheel's friction surface is glazed (shiny and smooth) or contaminated with oil from a leaking seal, the clutch may slip. You'll notice the engine RPMs increase when you accelerate, but the car's speed doesn't increase accordingly.
- Burning Smell: Extreme friction from a slipping clutch or a warped flywheel can generate intense heat, creating a distinct burning smell similar to burnt toast. This indicates severe wear and potential damage to the clutch and flywheel surfaces.
- Difficulty Shifting: A warped flywheel or damaged friction surface can prevent the clutch from disengaging cleanly, making it difficult to shift gears, especially into first from a stop.
Warning: Some light rattling or chatter at idle in neutral can be normal for a Viper's drivetrain and may not indicate a flywheel problem. However, if the noise changes or disappears when you press the clutch pedal, it often points to an issue within the transmission or clutch assembly that warrants inspection.
Buying a Used 2013-2017 Viper Flywheel
A used OEM flywheel can be a cost-effective choice, especially given the high price of a new unit. However, careful inspection is critical to avoid installing a bad part, which requires repeating a very labor-intensive job. Here’s what to check:
- Inspect the Friction Surface: This is the most important area. Look for signs of extreme heat, such as dark blue or black spots. Check for hairline "heat cracks" that look like a spiderweb on the surface. Run your fingernail across the surface to feel for deep grooves or scoring. A perfectly flat, dull gray surface is ideal. Avoid any flywheel with visible cracks or deep scoring.
- Examine the Ring Gear: Carefully inspect every tooth on the outer ring gear. Look for any chipped, broken, or excessively worn teeth. The edges should be relatively sharp, not rounded or mushroomed over. Damaged teeth can cause starting problems and damage your starter motor.
- Check for Warpage (The Invisible Killer): The biggest risk with a used flywheel is warpage, which is impossible to see with the naked eye. A warped flywheel will cause clutch chatter and engagement problems. This is why it's crucial to buy from a reputable automotive recycler that guarantees the part is straight and serviceable. Ask about their testing process and return policy.
- Verify Part Numbers: Ensure the part is a genuine Mopar 5038699AA or 05038699AA. This flywheel is specific to the 2013-2017 Gen 5 Viper and is not compatible with earlier generations.
Replacement Difficulty & Labor Costs
Replacing the flywheel is a major undertaking that requires removing the entire transmission.
- Difficulty Rating: 5 out of 5 (Professional level). This is not a typical DIY job. It requires a vehicle lift, a transmission jack, and specialized tools.
- Estimated Time: A professional technician typically takes 5-8 hours to complete a clutch and flywheel replacement.
Pro Tip: Since the transmission must be removed to access the flywheel, it is highly recommended to replace the clutch disc, pressure plate, pilot bearing, and rear main engine seal at the same time. The cost of these additional parts is small compared to the cost of the labor should they fail later.
Cost Comparison
Prices can vary based on location and supplier. The estimates below are for comparison purposes.
| Part/Service | Estimated Cost | Notes |
|---|---|---|
| New OEM Flywheel | $700 - $1,200+ | Price and availability can be challenging. A 2008-10 OEM flywheel was listed for over $700. |
| New Aftermarket Flywheel | $700 - $1,400 | Includes lightweight aluminum options from brands like Fidanza, which may alter driving characteristics (e.g., more idle chatter). |
| Used OEM Flywheel | $250 - $500 | A good value if properly inspected and guaranteed to be flat. |
| Shop Labor (Flywheel & Clutch) | $500 - $800 | Based on an estimated 5-8 hours of labor. RepairPal estimates labor costs for a Viper clutch job between $489 and $718. |
Frequently Asked Questions (FAQ)
Can I resurface my 2013-2017 Viper flywheel?
It is strongly recommended that you do NOT resurface the Viper flywheel. Service manuals and expert consensus advise against it. Removing material can alter the precise geometry required for the hydraulic clutch system to work correctly, potentially leading to disengagement problems. Given the high labor cost, replacing the flywheel with a new or guaranteed-good used unit is the safest option.
What's the difference between a flywheel and a flexplate?
A flywheel is used with a manual transmission and provides a friction surface for the clutch. A flexplate is used with an automatic transmission and connects the engine to the torque converter. The 2013-2017 Dodge Viper only uses a flywheel because it was only sold with a manual transmission.
Do I have to replace the flywheel when I replace my clutch?
While not strictly required if the flywheel is in perfect condition, it is highly recommended. The flywheel surface wears along with the clutch disc. Installing a new clutch on a worn, glazed, or heat-damaged flywheel will significantly reduce the new clutch's performance and lifespan. Considering the labor involved, replacing both at the same time is a wise investment.
What causes a flywheel to fail?
The most common causes are heat and friction from normal clutch use over many miles. Aggressive driving, such as hard launches or slipping the clutch excessively, can accelerate wear and cause overheating, leading to warpage and cracks. Oil contamination from a leaking rear main seal can also ruin the friction surface.
