problem #1

May 132008

Sierra 1500 5.3L V6

  • Automatic transmission
  • 13,049 miles

I bought two of these pieces of junk, neither one can keep a tranny in. Also replaced a transfer case, drive shafts, exhaust systems, power steering pumps, front diff, rear diff's, alternator's, power windows don't work, the 2wd gets 11 mpg and the 4wd gets 8mpg. A long way off the 27mpg the window sticker says. Stay away from GM, there's a reason they are bankrupt!
