1996 GMC Sierra V8 Four Wheel Drive Automatic 212000 miles
My '96 GMC 1500 has a rebuilt automatic transission with around 60,000 miles on it. The issue is that when the truck is in gear there is a scraping noise. When I put the truck in neutral or park the sound goes away. The transmission has been serviced about 20,000 miles ago. The fluid looks good and is at a good level. Ideas?
