My 2000 F350 7.3L Powerstroke Turbo Diesel

My 2000 Ford F350 with 7.3L powerstroke turbo diesel engine, new turbo, superchips tuner, intake, exhaust and some add ons. Tranny just stopped working. Was told it's a common problem of the feed bolts backing out and might not cost much to fix. For sale $7500
