New at posting but have been here reading many times, Thanks. I have an 86 f350 6.9 4 speed manual, It sits in my shop with a camper on just waiting for hunting season most of the time, I've owned it for about 30 years. It sat all winter, I usually start her up every couple months during winter. I went camping 3 weeks ago and drove about 500 miles, everything ran good. Last week I loaded up for a scouting trip 450 miles away. I got up and left at 5am, when I backed up to leave the tranny ground really hard going into reverse, I headed down the road and it ground hard and didn't like changing gears, I pulled over 3 times and re-started, each time it would grind hard going into every gear, so I decided I had to bag the trip, I turned around in a driveway and headed back home, as I shifted though the gears it went smooth so I pulled over three times on the way back home (1 mile) and went through the gears, it worked good, problem was gone, so I turned around and headed back out. I drove over 900 miles in the following 5 days with my fingers crossed and considerable anxiety with no problems. I'd like to know what was causing this so I can fix it or stop worrying about it. My suspicion is that the clutch was not releasing all the way, it's adjusted good and has plenty of fluid. Is it possible for a piece of friction material to break of the clutch and lodge between the clutch and flywheel and cause a drag until it was spit out??That's what it felt like. I checked all the bushings and adjuster rod under the dash and all was tight. Maybe the linkage to the tranny? Any Ideas????
