Turn signals/emergency button= trans downshift ?
I have a 1996 F-250 7.3 Crew Cab. Over the past year and out of the blue the trans would shift out of overdrive locke out at steady throttle for a second or two then go back into lockout. Recently the wife was driving the truck on the freeway and said everytime she used the turn signals the speed control kicked out. Low and behold I was finally able to duplicate that but also discovered that while driving without the s/c, but at steady throttle, the trans would kick out of overdrive lockout when I used the turn signals... That was intermitten... I decided to activate the emergency flasher button during steady throttle and I kicked the trans out of overdrive lockout everytime
