Which is the best Duramax 6.6L turbo diesel?

Perhaps the shortest lived of the 6.6’s, the LBZ Duramax is one of the most desirable amongst diesel enthusiasts today. The LBZ has the best performance and horsepower potential with bolt-on mods and was paired with a stronger Allison transmission than found in the LLY Duramax.

What kind of transmission does a Duramax diesel use?

It was the first to come bolted to the six-speed Allison transmission which provides a lower cruising RPM and greater fuel efficiency when compared to the five-speed on the LB7 and LLY.

Overheating issues with the Duramax diesel seems to be a hit-or-miss problem; some owners experience it, while others never will. Regardless, it’s more common with the Duramax than other engines.

What happens when a Duramax engine goes down?

Not only does this mean game-over for the engine, but it results in a truck that’s down for weeks (if not months) and a huge chunk of change missing from your wallet. The failure is most common in higher horsepower engines, but can still occur in moderately modified and even stock power plants.

Why is my Chevy Silverado having transmission problems?

When a torque converters wears, its vanes start to bend, which means that it cannot accurately control the movement of fluid inside the bell housing, causing erratic performance.

When was the Duramax LBZ engine phased out?

When you couple the performance potential with the reliability, and lack of emissions regulating systems, it’s no wonder the LBZ is still the fan favorite over 13 years since its discontinuation. The engine was phased out in 2007 solely for the purpose of emissions regulations.

What should the temp of an Allison Transmission be?

How hot should your Allison transmission run? If you own a 2001-2004.5 LB7 Duramax your normal operating temperatures will run around 160-180 degrees.

What causes a Duramax diesel engine to heat up?

When the engine is working hard, the turbocharger is drawing in a ton of air, and the restrictive stock turbo inlet tube can effectively choke the VGT turbocharger causing the compressor outlet temperature to skyrocket, heating up the intercooler, and ultimately raising the temperature of combustion and the coolant temp.

Why is the odometer on my GM Truck not working?

First.it’s not a thermostat issue.

Where is the temp sensor on a GM Truck?

Replace the “temp switch”. It’s on the right side of the block, in between the exhaust headers, it’ll have a single green wire going to it from past the alternator. They cost like $20, and it’s an easy replacement. Be sure to get the “temp SWITCH” and NOT the “temp SENSOR”.
