    Default 2010 Silverado lunge and stall

    I am having trouble with my 2010 Z71 wanting to lunge and sometimes stall when I come to a stop. Has anyone had this problem or know what is causing this?

    Sounds like the transmission tork converter is not unlocking untill you come to a stop, bring it back to the dealer and have them run a diagnostic on the powertrain. If you want to see if the converter is unlocking drive the truck at say 60mph then while your foot is on the gas to maintain speed, gently touch the brake pedal just hard enough to to turn on the brake lights, watch the tach needle it should jump up about 300-400 rpm, if it does not then you have problems. Good luck, be carefull.
