2003 F150 V6 108000 MILES This morning I started my truck in park then shifted to reverse. The engine revved up then slammed into gear . Getting on the highway the transmission would not shift into 3rd or overdrive At first the symptoms seemed to be a broken servo retainer but after taking out the valve body the retainer was still in place ,the valve body was clean everything moved nothing stuck The filter was alittle dirty but no chunks anywhere the fluid was full and not burnt I dont have any codes my micky mouse autozone code scanner doesnt show anything but the shifter light was flashing so there has to be something Im thinking electrical rather than mechanical, Shift solenoid , tps TCC epc Bfd Where do I start?:::
