Transmission shifter issues
Shifted back to reverse and it moved, back to Drive and it moved but it now goes forward in any shifter position except park. Park holds and comes out just like normal. The shifter indicator moves like it's working but it's not. No grinding or scrubbing noises. Eased back into the driveway. Any thoughts or ideas appreciated. I have not made any close examinations yet. My shop is my gravel driveway, it has rained the last couple of days, it's 30 degrees outside and it's dark. I will check it over tomorrow but thought I would ask in case anyone can tell me what to look for. 
First thought was to post this in the 6.0 forum, but decided to try here first. Thanks
