No power in drive

[Andrew]

I have a 2003 ford f150 with about 79,000 miles on it and everytime i put it into drive it would have just about no power and my overdrive light is flashing and it seems like reverse has more power than drive. In drive I could floor it and it would barely move and i have pulled these codes: P0443, P0403, P1451, P1747, P0755, P0743, P0135, and P0155. Does anyone know what happened?

Looks like those codes point to a few things; some issues with the EVAP system and some issues with the transmission solenoid, torque converter.

How’s the fluid level in the transmission? How are your fuses?
Have you inspected the wiring that runs to the transmission? I wonder if something rubbed or melted. On some of those vehicles they run the wiring harnesses above the exhaust at one point. I’ve seen them melt or rub against the body of the vehicle and short to ground.

I’ve also seen squirrels chew through things and cause fun issues.

Probably; Fuse F23 in the under hood fuse box is open, caused by the passenger side o2 sensor wiring harness grounded against the exhaust manifold.
