Im having trouble diagnosing the codes my truck is throwing which are: p1886 Shift timing solenoid, p1860 Tcc pwm solenoid circuit - electrical, p1864 4-5 shift solenoid valve control circuit low voltage, as well as p0758 and p0753. The truck ran fine one day and quit the next. When I got in the truck the tachometer, speedometer, and the indicator light for gear selection wasn't working. The transmission is also like its in a failsafe mode and stuck in third gear. Its real sluggish on takeoff and will not shift up or down. Not really sure where to look on this issue. I've read several things about several different sensors that would cause this but im at a standstill right now. I have a brand new pcm that I tried but the same codes came right back and I've also replaced the shift interlock solenoid on the column with no luck.
