2006 Chevrolet W5500HD Tiltmaster
The 2006 Chevrolet W5500HD Tiltmaster is a cab-over-engine (COE) medium-duty truck popular for its maneuverability and relatively compact size, making it suitable for urban delivery and service applications. It’s often praised for its ease of maintenance due to the tilting cab design. However, some drivers find the cab-over design less comfortable on long trips compared to conventional trucks. The 2006 model year typically offered the Isuzu 4HK1-TC 5.2L Turbo Diesel engine, producing approximately 200 horsepower and 441 lb-ft of torque. The available transmissions were typically the Aisin A465 6-speed automatic. Dislikes often center around the utilitarian interior and limited driver amenities compared to modern trucks.

Summary
The 2006 Chevrolet W5500HD Tiltmaster can be a reliable workhorse, but potential buyers should be aware of common issues, especially those related to the engine and transmission. Turbocharger and injector problems are common on the 4HK1-TC engine and can be expensive to repair. Transmission issues such as harsh shifting and torque converter failure are also possibilities. Electrical and suspension problems can also arise as the vehicle ages. Addressing rust is also crucial for long-term durability. Overall, while some of these issues can be costly, a well-maintained W5500HD can still provide years of service.
