Loss of radio sound solved!!!!!
I had the same issue as many posted when I performed a search about losing sound when the truck was put into DRIVE or REVERSE, Well I searched for a possible answer but all that came up was the Neutral safety switch, I took my truck to my local dealer and they found the issue.....it ended up by being the " transmission ranger sensor "
So not sure if this was already posted as a solution but here it is if it hasen't,
ciao for now!
