If you’re a Duramax diesel enthusiast or truck owner, you’re likely familiar with the Allison 1000 transmission. Revered for its durability, smooth shifting, and ability to handle the power of diesel engines like the GM Duramax, it’s a popular choice in heavy-duty trucks. However, even the best transmissions aren’t immune to problems. In this detailed guide, we’ll combine insights on diagnosing common issues, troubleshooting tips, and upgrading your Allison transmission to ensure your truck keeps running strong under any condition.
David Schaefer’s 2015 GMC 2500HD Denali, known as "Time Bomb," is a remarkable achievement in the world of diesel performance. With a stunning 700 horsepower while maintaining full emissions compliance, this truck is a testament to what can be accomplished with thoughtful engineering and high-quality components. Let’s break down this comprehensive build, exploring the features that make it special and how they come together to create a never before achieved driving experience.
Diesel engines have many nuances when compared to their gas counterparts, fuel injectors being one of them. Unlike fuel injectors used on direct injection gasoline engines, diesel injectors often have a higher failure rate and shorter lifespan due to their more extreme operating conditions. When these injectors fail, it can lead to a cascade of performance issues, increased emissions issues, and even engine damage.
Adding power to your diesel, whether it be a Cummins, Powerstroke, or Duramax, can be a fun and rewarding experience. However, when it comes to upgrading an emissions in-tact truck options can sometimes be limited and results can often be underwhelming. But that doesn't mean you have to suffer with poor performance, complicated upgrades or the cost of removing your emissions components! Emissions in-tact custom tuning is a solution that will not only blow you away in terms of performance and ease of installation but it can also improve the performance gains from other aftermarket upgrades that may not be pulling their weight as they stand.
Unleashing Hidden Potential Without Compromising Emissions
Emissions In-Tact Custom Tuning is specifically designed to optimize the performance of your diesel truck while keeping all emissions systems fully operational. This means you can enjoy improved power, torque, and fuel efficiency without the need to remove or tamper with your truck’s emissions equipment.
As the winter months rolls around us diesel owners get an unexpected bit of stress added to our plate. Diesel fuel gelling is a very common issue most diesel owners who live in areas where the temperature drops below 32 degrees will face at least once in their lives. Not only is this issue frustrating and stressful when it occurs, the mere trauma from past experiences can lead to constant stress during these cold times. No one wants to get out of work in the pitch black freezing cold only to find that their truck won't start at all. But what should you do in the event that your truck won't start or stay running? Luckily we have a step by step guide on how to properly fix this issue once it has occurred.
As a preface, this issue is caused when the paraffin wax used in diesel fuels (for lubricity and proper viscosity) start to solidify. While gelling can take on varying levels of severity from cloudy fuel all the way to a squishy solid mass. Diesel fuel gelling is never a thing you want to expeirince. At its most mild levels it can cause poorer fuel economy, less power, and be pretty hard on your fuel system. At its worst I can clog fuel lines, filters, pumps and even injectors while potentially causing irreversible damage to your fuel system. If you live in a cold climate take precautions by adding anti-gelling agent into your fuel before severely cold temperatures start setting in to avoid all of these issues.
Over the years, GM has changed a lot regarding the turbos they use on Duramax engines. Not only have they changed manufacturers a handful of times but each RPO has its own unique measurements for key components. This can make it a headache when trying to track down exactly what the measurements of your stock turbo are. Luckily we've compiled this list of stock Duramax turbo specifications along with other helpful information so you can get a good idea of what you're already working with before you dive into the sea of turbo upgrades these trucks have to choose from. However, while some turbos may have the same peak power output, the size and shape of specific components can affect things such as exhaust gas temperature, drive pressure, and turbo efficiency range.
The 3.0L Duramax is a wildly capable inline 6-cylinder diesel engine designed for full-size half-ton pickup trucks and SUVs. Due to its amazing power-to-weight ratio and towing performance, GM has chosen to offer this engine in everything from Chevy Silverado 1500 to the Chevy Suburban and even the Cadillac Escalade. Clearly, GM is confident in its new design.
The new 3.0L Duramax shares very little in common with its predecessor the 4-cylinder 2.8L Duramax. It's been completely redesigned from the ground up and features many improvements such as a forged crankshaft, forged steel connecting rods, and a much stronger block design. The result is an engine that can produce 277 hp and 460 ft-lbs. of torque. Which is comparable torque to that of the more expensive 6.2L gas engine that is offered in most of the same vehicles that the 3.0L is offered in.
What's an RPO? Crucial Duramax Information!
This article will help you understand what an RPO is, how to find yours and when it will be needed. An RPO or Regular Production Option is a GM-specific code, made up of 3 characters, that helps the manufacturer specify what configuration of options has been or needs to be applied to a vehicle. This can include anything from paint color to powertrain options. For Chevy/GMC Duramax trucks each type of engine can be signified by a different RPO code.
