Trailblazer LX V6

This transmission seemed to be slipping from day one. the bad thing is the new one does the same thing and I'm supposed to accept that because "that's the way they are"

Trailblazer LT 4.6L

  • Automatic transmission
  • 75,000 miles

General Motors has admitted that they have a problem with the 4L60E transmissions that they use in the Trailblazer, Envoy, and Bravada lines. The reaction sunshell and reaction sungears fail. These are faulty parts from the manufacturer and us as the consumers are having to pay for this. They admitted the problem in their TSB #00822B but don't want to help pay for or all of the repair cost. You can also find this problem on the NHTSA site under #10005474. Get the word out, GM needs to own up to this and help there customers.
