NHTSA Complaint #10331690 — 2003 GMC ENVOY

THE TRANSMISSION FAILED IN MY 2003 GMC ENVOY WITH APPROX 95,000 MILES. WHILE DRIVING DOWN THE ROAD I WENT TO PASS A SLOW MOVING VEHICLE. AS THE TRANSMISSION DOWN SHIFTED THERE WAS A "BANG" SO I PULLED OVER TO LOOK UNDER THE TRUCK, AND MADE SURE NOTHING HAD FALLEN OFF. I GOT BACK IN THE S.U.V. AND MADE MY WAY BACK HOME WITH NO PROBLEM. THE NEXT DAY WHEN I WENT TO BACK OUT OF MY DRIVE WAY THERE WAS NO REVERSE. I CALLED A LOCAL GM DEALERSHIP AND WAS TOLD THAT THE PROBLEM APPEARS TO THE SUNSHELL GEAR. ACCORDING TO MULTIPLE POST ONLINE, SEEMS TO BE A COMMON FAILURE AMONG ENVOY'S AND TRAILBLAZER. I CHECKED THE FLUID AND IT APPEARS TO BE FINE, NOT LOW, NOT BURNT, AND STILL RED AND CLEAN. *TR
