7th Place Chevrolet Silverado 2500 LTZ Crew 6.6L Duramax
What’s New
he truck is new for 2020 and General Motors matched its Duramax L5P 6.6L V-8 to a clean-sheet, GM-built, Allison-branded 10-speed gearbox. The 10L1000 comes with a list of features designed to get all of the Silverado 2500 LTZ’s 910 lb-ft of torque straight to the ground, including a variable-rate pump; high-performance clutch packs and solenoids; a factory-installed PTO pump option; and a stiffer, one-piece housing that bolts directly to the transfer case instead of having to use an adapter like the previous Allison six-speed.
