2006 F150 2wd automatic 150k miles - Without warning it was like I bumped it into neutral, no gears, not even a sound like it trying! Park works, reverse light comes on, starts in neutral and park. Changed fluid / filter inspected valve assembly, no trauma, no broken clips, no burning smell or chunks of metal. I'm not getting any "Service Lights" no error codes. Shifter is connected, everything is hooked up. I'm stumped.
