I have a 88 d 100 2wd 4 speed with a OD and trans is making a noise in and out of gear except 4th. When putting inR it grinds most of the time and 3rd use to. Going into 1st is hard most of the time.Stopped by a trans shop and he said it may/will need gears,orings and seals at least and will be $750.00 -800.00 and the most will be $1200.00 Going to tell the wife today and her Durango just replaced the wheel bearing/hub sat and needs outer tie rods on both sides,alignment,tires and trans flush or what joy
