LT 2009 Used Automatic Gasoline Chevrolet Trailblazer 2009 Gearbox Clean, God willing, it has no issues. The gearbox type is 4L60E, it might fit other cars. The reason for selling is that after a wrong diagnosis from several places assuming the gearbox was damaged, but the gearbox is fine. The problem was with the flywheel, and after that, I bought a new one and no longer need to change the gearbox. For sale for 3000. Contact via WhatsApp.
