When did the LLY Duramax go to 6 speed?
When did the LLY Duramax go to 6 speed?
It was mated to a 5-speed Allison Transmission in years 2004 and 2005. In 2006, the Allison Transmission was upgraded to a 6 speed. Although our LLY Duramax specifications chart above does mention the turbocharger found on these trucks, it doesn’t mention the fact that these are one of the largest turbochargers found on any Duramax today.
Is the LLY Duramax the same as the LB7?
Similar to the LB7, the LLY Duramax is reliable, powerful, and lacks most of the emissions found on modern day diesel trucks like the L5P. LLY Duramax trucks don’t suffer from the same injector failure problems that LB7 trucks frequently had. Instead, many LLY Duramax problems stem from overheating.
What’s the tow capacity of a LLY Duramax 5th Wheel?
The LLY Duramax was sold from 2004-2006 and tow capacity varies between model years. Conventional tow capacity across all models is 12,000 lbs. 5th Wheel tow capacity varies between years and depends on cab configuration. Numbers generally fall between 15,000 lbs and 16,700 lbs though.
How big is a LLY Duramax diesel tank?

Are there any problems with the LLY Duramax?
In terms of LLY injector problems, GM had sorted out the internal failures with the 2004 ½ redesign, but the LLY Duramax would occasionally exhibit a trouble code for the injectors, but in most cases it turned out to be an issue with the injector harness rubbing through and causing a short or open in the wiring.
When did LLY 7.8L diesel engine come out?
• New LLY 6.6L and LG4 7.8L engine information is added for diesel engines sold after 1/01/2004. (See LLY and LG4 ECM Connectors and Location Drawings.) The new engines require new Engine Control Modules. The LLY ECM changes from a 2-way (on the LB7 ECM) to a 3-way connector, and the new LG4 ECM from a 5-way to a 2-way connector.
What makes a Duramax LB7 diesel so special?
The introduction of common rail injection powered by the Bosch CP3 injection pump made the LB7 Duramax stand apart from other diesels of the day with excellent power and efficiency.
What are the specifications of a LLY Duramax?

How many horsepower does a GM LLY have?
It was a stepping stone for GM as they begun to encounter stricter emissions requirements thanks to the federal government and California. Despite the added emissions, the LLY was very powerful and capable for the time producing 310 horsepower and 605 lb/ft of torque. It was mated to a 5-speed Allison Transmission in years 2004 and 2005.

What was the problem with the LBZ Duramax in 2006?
Glow plug failure was a concern on the 2006 model year LBZ and LLY Duramax models, but the problem should have been long corrected for owners of these years. The concern was that the glow plug module would over cycle the glow plugs, creating a scenario in which the tip of the glow plug could actually deform and/or break off in the engine.
What are the most common LLY Duramax engine problems?
The 6 Most Common LLY Duramax Problems. 1 1. LLY Bent Rods. While the LLY made competitive performance numbers back in 2004, the engine is certainly not competitive to the modern day diesels. 2 2. Head Gasket Failure – LLY Duramax. 3 3. EGR Valve Failure. 4 4. Glow Plug Failue – 2006 LLY Duramax. 5 5. Overheating in Pre-2006 Models.
Is there a lift pump for the LLY Duramax?
Although the injector issues of the LB7 Duramax didn’t carry over to the LLY, the second generation Duramax still has its fair share of problems. Just like the LB7, no lift pumps were included on these trucks stock. An aftermarket lift pump like a Fass or Air Dog should be one of the first upgrades you consider.
What’s the weight of a Duramax 4 wheel drive?
Numbers generally fall between 15,000 lbs and 16,700 lbs though. Duallies and two-wheel drive models also offer higher tow ratings. Larger cabs and 4wd models offer less 5th wheel tow capacity.
Are there any problems with the Duramax water pump?
This seems to be inherent of the factory water pump design. 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 do you need to know about the 6.6 Duramax?
Things like exhaust and intake are also very common mods. Diesels are known for being able to chug along for millions of miles. However, with the new emissions systems on modern diesels the longevity of the engine has decreased. The 6.6 Duramax has a few emissions systems that almost everybody ends up deleting:
