Duramax, Chevrolet and GMC Horse Power and Torque

 

This article is about the Chevrolet Silverado and GMC Sierra (GM) pickup trucks mated with Duramax diesel engine with some specifications and history.  The Isuzu and GM coop’d the 6.6l turbo diesel engine design that has put Chevrolet and GMC on the map for consumers and diesel truck lovers.  In 2001, the Duramax turbo diesel was introduced to the GM 3/4 ton, 1 ton trucks and commerical trucks.  In 2004.5, the EPA required a catalytic converters (Cat) and exhaust gas recirculation (EGR) on the LLY engines.  In 2008, the EPA again required stricter emissions and required the first Diesel Particulate Filter (DPF) as well as the Cat/EGR.  In 2011, improvements were made in the emissions systems by the new Urea injection system that didnt hurt performance.

The Allison 1000 automatic transmission has been the in the large amount of GM trucks built with the Duramax however you could order a 2001-2007 GM truck with a ZF S6-650 manual transmission.  Interesting enough, the ZF S6-650 manual transmission ZF Friedrichshafen AG was used in the 1999-2003 Ford F-250 and F-350 trucks previously.  This transmission was discountinued in 2007 by GM.
