I know it's probably a long shot but figured I would ask anyways. Long story short I had my truck in 4high (towing through mud) afterwards with no trailer hooked up I hit the road in front of my house to knock all the mud off just a couple short launches nothing to bad. Afterwards pulled back into my driveway and went to back up and turn around. Realized I had no reverse it just acted like it was still in D. Immediately noticed column shifter wasn't smooth and every gear does the same thing but almost feels like it's in limp mode also. I've been looking and reading and leading me to think it might be the trans position sensor inside the pan. I tried changing fluid and filters but that didn't do anything and also checked for codes but there wasn't any showing up. Any help would be awesome.
