Keep Looking - 2005 GMC Sierra 2500HD
By Ken - January 3 - 6:20 pmI have the Duramax/Allison combination. It is a very sloppy running engine. Sloppy in that it is not efficient at burning the $3 plus/gallon fuel it takes to run her. She smokes and run your finger on the inside of the tailpipe and youll see what I mean. My guess is that in the hoursepower wars, GM spared no expense in trying to get ahead of the competition. They should have left the 0-60 nad quarter mile bragging rights to a more appropriate vehicle like the Camaro or Corvette. Im looking for a new owner for this one.

Sierra Duramax/Allison - 2005 GMC Sierra 2500HD
By SMD - July 20 - 1:46 amFuel mileage is poor at best. Engine surge and hesitation. Driveability is very eratic. Vehicle runs hot, fan runs excessively. Tranny and engine temp gauges always show 210 or better. All this while running vehicle empty. When towing all of the above is off the charts. GM answer is that all is normal.
