I was driving about 55 -65mph for about a hour and the OD light starts blinking? Ck'd switch and still blinking? Pulled in for gas ck'd all fluids and all good. restart no light....drive about 1 mile got to 60mph and something goes twang and the engine revs high like it's out of gear and the noise is like a screwdriver in the spokes of a bike? It's like it's in netural ?Pull off and shut it off try to restart and it sounds like just the starter is running....tow it home (on trailer) jack it up and yep just the starter is running? That's as far as I got...HELP !!

Thanks
Randy

Something with the engine is done. Sounds like something blew if you heard a ping noise.
