So don’t worry — with the Chevy Silverado, there’s not much you can’t tackle. Whether it’s a load of lumber for your next renovation project or an RV trailer for your next vacation, the Chevy Silverado delivers.

And when it comes to safety, the Silverado believes in giving you clear vision. You get 15 camera views with the latest model. It helps you tow with safety in mind so you can drive with confidence. more

There are two backseat storage compartments for stowing your extra gear while preserving legroom and sitting room space. [links]

First of all, let’s talk about what exactly tow haul does for truck owners. Tow haul mode is a feature that empowers your truck to tackle those heavier hauls with safety in mind. here

Just like the LBZ was the best pre-emissions 6.6 Duramax engine, the L5P is the best post-emissions Duramax. All the problems associated with emissions system and injection pump have been taken care of, and for 2017 GM switched suppliers of the injection pump from Bosch to Denso. Mechanically, the L5P Duramax is stout and very few major problems have been reported. One common problem is with the MAP sensor however, as it tends to clog with soot and throw a check engine light, but a simple MAP sensor spacer and a can of electrical cleaner can get you back on the road worry free and prevent the soot from building up again.

While it may not be the first place you think to look, the stock air intake system can actually contribute to a hotter running LLY Duramax. Many people add a cold air intake with hopes of increasing horsepower and efficiency, but on the LLY you need to take it one step further and add a less restrictive turbo mouthpiece, a part which doesn’t come with most cold air intake kits. 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. However, if you install a stock LBZ or aftermarket turbo inlet, you can let the engine breath freely which will lower air temps and keep the coolant temps under control.

Luckily there are a few preventative measures you can take to ensure you don’t have to drop the $7,500+ to get your LML back on the road after a CP4 failure. Just like an LB7, you can install a lift pump with better filtration which helps to clean air and debris out of your fuel which will minimize wear and extend pump life. Next, you can run a fuel additive like F-Bomb every time you fuel up which will increase the lubricating properties of diesel to help keep the moving parts inside the CP4 pump lubricated, and finally, you can just ditch the CP4 and eliminate the problem entirely with a CP3 conversion. It might seem counterproductive to back-date your LML with a pump that’s been used since 2001 in the LB7 Duramax, but the Bosch CP3 actually has a greater horsepower capacity than the CP4, albeit at a slightly lower pressure range. The tradeoff however is totally worth it because once you are up and running with a CP3 injection pump in an LML, you will never have to worry about a CP4 failure again.

In an effort to keep up with the ever-tightening emission regulations, GM redesigned its Duramax for the 2011 model year, and this time the code name was LML. Power was at an all-time high coming in at 397hp and 765 pounds of torque, and in order to provide this much power while still keeping pollutants low, GM needed to be able to increase the pressure in the fuel system to levels above what the tried-and-true CP3 could safely deliver.

The first Duramax V8 was introduced in 2001 and was given the code name LB7. 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. As the first batch of trucks started reaching the 100,000 mile mark, it became apparent there were some issues with the new engine, and one of the first symptoms exhibited would be a rough idle from the LB7, excessive smoke from the exhaust, long cranking times, and even fuel diluting the oil in the crank case. more

On paper, higher fuel pressure sounds good, but you can’t talk about common LML problems without mentioning the ticking time bomb of an injection pump. A class action lawsuit was even filed against GM for its use of the CP4, alleging the injection pump was designed around European fuels which have more lubricating properties than the ultra-low sulfur fuel which we’re accustom to stateside. As a result (allegedly), the lack of lubrication in the fuel can cause a premature failure of the injection pump, to a point where it won’t allow the LML Duramax to run. You can be driving down the road and everything seems normal, and when the pump fails, the truck just shuts off. At first you might think you can just swap out the pump for another and hit the road, but sadly this is not the case. Because of the nature of the CP4 failure, large amounts of metal shavings are produced inside the pump, and they get sent straight into the rest of the fuel system which contaminates pretty much everything. In order to properly repair an LML after a CP4 failure, you’ll need a kit which comes with a new injection pump, high and low pressure fuel lines (all the way to the tank and back) a fuel filter, a set of eight injectors, a pair of new fuel rails with bypass valves and you’ll even have to drop the tank to clean out any debris. here

I’m writing this as I sit in the waiting room of Courtesy Motors in Chico, CA. Two hours ago I brought my 2016 Cadillac ATS-V in, with 15,000 miles on it, for shifting shudders in the 8 Speed transmission. GM published a TSB calling for a fluid flush with Mobil 1 Synthetic LV ATF HP fluid. I was just now informed it will cost me $573 to flush the transmission because the bumper-to-bumper warranty has expired and they say the power train warranty doesn’t apply. Needless to say I’m not a happy camper. Time to leave GM after 39 GM cars over the past 53 years.

Sadly after many decades I decided to leave GM. It’s really a shame that they don’t have a viable fix for their faulty transmissions. I Traded the CTS two days ago, the Silverado in April. I’m not sure what I will do if the shudder comes back on my Stingray ☹️
