My 2010 T&C lost reverse. When I pulled fuse M28 the check engine light went off after plugging back in. When starting the van normally ill have all gears. Within 20-30 I'll loose reverse. Fluid is full. No leaks, at least nothing on the garage floor. Afraid to drive to get code checked, the nearest auto part store is 20 min away. Don't want to lose all gears in route. Lots of posts point towards solonoid. But I've read others say just to change fluid and filter. I don't feel its that simple but maybe I'm wrong. 172k on the van. No issues until recently.
