My 2003 Ranger with a M5OD is finally done. She’s headed to the transmission shop tomorrow to have it rebuilt. It never shifted great but a fill of John Deere Low-Viscosity Hygard solved almost all the issues except 5th gear whine. It is popping out of first and giving a harsh grind into second, it acts terrible in reverse. It feels like it tries to lock up when in reverse, grinds, bangs, the truck shakes and then moves fine for a bit. Told the shop to do everything, I don’t know how bad the damage is yet but I don’t want to open the transmission again after this for anything but a fluid change. I’ll post carnage pics here if there’s anything worth posting.
