Some owners feel the interior is dated and basic, even for its time.
Engine
5.3L Vortec V8
- Oil Consumption
- Description/Symptoms: Excessive oil consumption, requiring frequent top-offs between oil changes. Can lead to fouled spark plugs and catalytic converter damage if left unaddressed. Blue smoke from the exhaust is a common symptom.
- Solution: Replacing valve stem seals, piston rings, or complete engine overhaul/replacement.
- Estimated Cost to Fix: $500 - $3000+ depending on the severity and chosen repair.
- Recalls: None Found

- Estimated Cost to Fix: $300 - $600
- Recalls: None Found
6.0L Vortec V8
- Piston Slap
- Description/Symptoms: A knocking or slapping sound, especially noticeable at cold start. Often diminishes as the engine warms up. It is caused by the pistons moving slightly within the cylinders, creating excess noise.
- Solution: Some owners live with the noise if it’s not severe. Others opt for an engine rebuild or replacement to address the root cause (piston/cylinder wear).
- Estimated Cost to Fix: $0 (if ignored) - $3000+ (engine rebuild/replacement)
- Recalls: None Found

- Description/Symptoms: The truck starts to stall out randomly, or have difficulty starting. A check engine light will often illuminate.
- Solution: Replacement of the crankshaft position sensor.
- Estimated Cost to Fix: $100 - $250
- Recalls: None Found
6.6L Duramax Turbo Diesel V8
- Fuel Injector Failure (LB7 Engine Code)
- Description/Symptoms: Rough running, white smoke from the exhaust, poor fuel economy, and potential engine knock. The LB7 engine, used in the early Duramax trucks, is particularly prone to injector failures.
- Solution: Replace the failed fuel injectors. It’s often recommended to replace all injectors at once due to the labor involved.
- Estimated Cost to Fix: $2500 - $8000+ (replacing all 8 injectors)
- Recalls: Yes, there was a recall for fuel injector issues on early Duramax engines. Check with a dealer using your VIN.
- Glow Plug Issues
- Description/Symptoms: Hard starting in cold weather, excessive smoke on startup, and a possible check engine light.
- Solution: Replace the faulty glow plug(s) and potentially the glow plug controller if it’s also failed.
- Estimated Cost to Fix: $100 - $500+ depending on how many plugs are replaced and if the controller is also replaced.
- Recalls: None Found
Transmission
4L60E/4L65E (Four-Speed Automatic)
- Transmission Slipping
- Description/Symptoms: Transmission slipping between gears, especially noticeable under heavy acceleration. Delayed or harsh shifts.
- Solution: Can range from a fluid flush and filter change to a complete transmission rebuild or replacement. Often caused by worn clutches or valve body issues.
- Estimated Cost to Fix: $150 (fluid/filter) - $3000+ (rebuild/replacement)
- Recalls: None Found
- 3-4 Clutch Pack Failure
- Description/Symptoms: Loss of 3rd and 4th gears. The transmission may rev freely without accelerating when attempting to shift into these gears.
- Solution: Transmission rebuild or replacement.
- Estimated Cost to Fix: $2000 - $3000+
- Recalls: None Found
Allison 1000 (Five-Speed Automatic)
- Torque Converter Failure
- Description/Symptoms: Shuddering or vibration at certain speeds, especially under load. Transmission slipping, poor acceleration.

Summary
The 2000 Chevrolet Silverado 2500 is a generally reliable truck, but certain configurations and model years are prone to specific issues. Engine issues such as oil consumption and fuel injector failure on the Duramax diesel can be costly to repair. Rust is a significant concern, especially in regions with road salt. Electrical problems, such as instrument cluster malfunctions, are also common. While some issues are relatively inexpensive to fix, others, such as transmission rebuilds or engine replacements, can be quite costly. Potential buyers should carefully inspect the truck for rust, electrical issues, and signs of engine/transmission problems before making a purchase. The severity and cost of the issues vary greatly depending on the specific configuration, maintenance history, and location of the vehicle.
