  2. Air Bleeding Made Easy

    Sometimes it's the little things that make your life better. Although it is widely known that under-hood temperatures in diesel trucks can fatigue sensitive components like wiring, connectors, hoses, and more, it's important to note that time also plays a big role in the degradation of these parts. The longer trucks are in service, the greater the possibility of there being more failures.

  3. Fixing the Dreaded GM “Pump Rub”

    Owners of four-wheel-drive General Motors pickups from 1997 to 2010 should all be aware of the dreaded "pump rub" issue. It doesn't matter if you drive a Silverado 1500, Sierra 3500, or even an Avalanche, if your truck has a transfer case, this story is for you.

  4. Flow To Go!

    The Bad

    When the LLY engine was designed, the intake was made to be free-flowing, but the post-turbocharger intake horn was not. In fact, it’s much, much smaller than the turbocharger inlet, which creates a bottleneck, especially at wide open throttle or when towing. Remember that the turbo will still try to force the air into the engine, creating higher boost pressures and hotter air (and therefore higher exhaust gas temperatures and engine operating temperatures.)

  5. Chevy 2500HD Allison Transmission Rebuild

    When we first rolled our 2002 Chevy Silverado 2500HD into the bay at PPE Diesel's shop in Montclair, California, we thought for sure the transmission was toast. Interestingly, upon inspection it was actually in relatively good shape despite likely having more than 200,000 miles on a truck that was pushed hard enough to melt a piston and head. This just further reinforced the notion that with regular fluid and filter changes the Allison 1000 transmission should outlast the truck.

  6. Duramax Tuner 2001 to 2005 Allison Six-Speed Conversion Kit

    There's an interesting thing about early Chevrolet Silverado and GMC Sierra trucks equipped with the Duramax diesel engine and Allison transmission. From 2001-2005, these trucks were equipped with a five-speed Allison automatic transmission. In 2006, the trucks received a big update, a "new" six-speed Allison transmission. The interesting discovery came after the new transmission was torn down for the first time. It quickly became apparent that the internals were, for the most part, exactly the same.

  9. 2020 Pickup Truck of the Year

    Pickup Truck of the Year doesn't happen in a vacuum—it requires the involvement of dozens of people and agencies spread all across the country, and we'd be remiss if we didn't at least give them a shout-out. First and foremost, we must say thank you to the men and women who make up the marketing and communications teams at each of the OEMs. Without their help and support this test wouldn't happen. In addition, we would like to thank the West Coast vehicle prep companies, Page One Automotive and Motus One, which handle the difficult logistics of getting the plethora of pickups to us.

  10. Maximum 'Torc

    It’s not often you run across a diesel-powered vehicle that’s unlike any other, yet that’s exactly the case with Weaver Customs’ ’70 Cuda. Nicknamed “Torc” (for obvious reasons), the 6.7L-powered Cummins Cuda is a unique blend of a high-end show car, a muscle car, and a diesel drivetrain swap. When looking over the car, there are no spots where we could find any body errors, turbo oiling or exhaust issues, or diesel clearance problems. Randy Weaver clearly thought this one out from the ground up when he debuted his newest creation.
