Trans codes are p1747 p0755 p0743. My o/d light is blinking and truck has loss of power. It will rev in drive, but in gear no power. It's a 2001 Ford F-150 4.6. I changed A and B solenoid, spark plugs, coils, fuel pump, fuel filter, and cleared codes. Started truck and codes came right back.
Check your fuses. There is a power-train control module that may not be getting power.
If not check the wiring harness' from the transmission. There are several. Check for chaffing anywhere along the line.
i found this
transmission turbine (overdrive) usually they crack and work for a while then just stop and keeps the truck from running smooth.
im guessing you checked fluid level and checked for leaks
dont know if this helps
