MY 2001 CHEVY TB HAS ALREADY HAD THE TRANSMISSION REBUILT AS THE RESULT OF A SUN SHIELD FAILURE AT 36K MILES. AS OF RIGHT NOW I AM AT 90K AND IT IS FAILING AGAIN. A QUICK SEARCH THROUGH EDMUNDS.COM SHOWS THIS IS NOT AN ISOLATED INCIDENT. CHEVY HAS DONE NOTHING TO RECTIFY THIS AND SINCE THEY WERE THE ONES WHO SUPPOSEDLY FIXED IT BEFORE, THEY HAVE OBVIOUSLY NOT ATTEMPTED TO ENGINEER AN ADEQUATE FIX FOR THIS FAILURE. IF THIS FAILS ON AN INTERSTATE THERE WILL BE A SERIOUS SAFETY ISSUE FOR ME AND MY FAMILY. *CN
