It's very unlikely that having the wrong tires will cause a P0755 code.

If the fluid level and condition is OK and you are still having the same problem, then you may have a problem with the solenoid or an electrical problem. What model and year is your Ford?

The information above is the same for the 2001 F150 Super Crew Cab. You probably have a faulty shift solenoid 2 valve.

2004 focus auto 16v, replaced solenoids 1&2, filter, 1gal fluid, gasket, still throwing 0755. Not much debris in pan, cleaned it all up. Still shifts rough, but better than before replacements.

2006 Ford E250 Super Duty with 4R70W Transmission. Truck has
the CEL on and the OD light is flashing. Truck seems to drive fine but when trying
to accelerate from a complete stop it slam into gear unless it is manually
shifted into first gear. Engine code is P0755.
Took the truck to a local Ford Dealer and was told I needed
to replace Shift Solenoid B. Solenoid was replaced. Replacing the solenoid made
absolutely no difference in performance.
Took the truck to a Transmission Repair shop and was told it
needed a complete transmission rebuild.
Complete transmission overhaul made no difference in performance. Truck
still has the same problems.
Was told by a second Transmission shop that the valves were
sticking and it needed a new valve body. New valve body came with new shift
solenoids. Installation of the new valve body has made absolutely no difference.
Any ideas of what to do next would be greatly appreciated.

It throws codes p0750 and p0755. Shifts fine, reverse fine. But the overdrive light is flashing and it won't kick into overdrive. Could it just be those solenoids?

What model and year is your vehicle? You probably have to replace the solenoid pack.

Hello. My problem ended up being a faulty wire in the transmission's internal harness that connects to the shift solenoids. Hope this helps.

You probably have to replace the solenoid pack, but before replacing the solenoids, you could start by just changing the transmission fluid and filter.
