[mytrucksux]

Anyone ever heard of this! 2004 f-250 4X2 6.0. going down the HWY at about 80mph truck goes into reverse. Barely kept control. turned off and restarted all is OK drive it to work. open up tranny and change trans range sensor. as per dtc code. two weeks later same thing. replaced wire harness to pcm about three weeks later reverse again. replaced pcm two weeks later reverse. studied wire diagrams and found everything is connected to this tranny. I'm a learjet tech. and really good with electrical problems but this one is beyond me. any help is greatly appreciated. out of money and patience. thanks!!
