A refresh followed with all 2010 models, including new interior door panels (which moved the handle forward and added an additional cup holder) and a six-speed automatic transmission on regular cab models with the 5.3L V8 was also made standard. The Vortec 6200 V8 was given wider availability, now being optional on LT and SLE extended and crew cabs, completely supplanting the light-duty Vortec 6000 V8 in the process. The new Z71 Appearance Package was optional on LT and LTZ, it included: body-color grille and front fascia, body color door handles and mirror caps, unique Z71 box side decals, chrome sill plates, and a unique Z71 gauge cluster. Two new exterior colors were added: Taupe Gray Metallic and Sheer Silver Metallic.
