Consumer Description

I HAVE A 2003 GMC ENVOY, 80,700 MILES ORIGINAL OWNER. WHILE MERGING ONTO HIGHWAY TRANSMISSION LOCKED IN 2ND GEAR. ENGINE RPM'S INCREASED TO 5,000 SPEED DROPPED TO 20 MPH CREATING A DANGEROUS SITUATION WITH ONCOMING TRAFFIC. THIS HAPPENED WITHOUT WARNING OR ANY INDICATION OF A PROBLEM. I HAD VEHICLE TOWED TO GMC DEALER, ASKED IF THERE WERE ANY KNOWN PROBLEMS WITH GMC ENVOY TRANSMISSIONS AND WAS TOLD THERE WERE NONE. THE DIAGNOSIS, MY TRANSMISSION EXPLODED INTERNALLY WITH A FAILURE OF THE SUN SHELL GEAR AND TORQUE CONVERTER. TRANSMISSION COULD NOT BE REBUILT AND THE COST OF INSTALLING A RE MANUFACTURED TRANSMISSION WAS $3700! GM HAS BEEN HAVING THESE TRANSMISSION FAILURES SINCE 2002 WITH NO ACKNOWLEDGMENT OF LIABILITY! *TR
