I have a 2002 GMC Sierra 2500HD w/ allison transmission. When I pull the shifter into drive the letter D does not highlight anymore showing that I'm in drive. The truck stills goes into drive until today when it would only go into park and reverse. It did go into drive after trying a couple of times. There isn't any noise or any other issues.
