After my last thread on here 2010 Ford Focus won't start (no crank) or shift out... , I replaced the shifter as suggested and replaced the starter related fuses as a precaution.

It starts, but won't shift out of park. Doing so with the override, reverse doesn't seem to work. Would an issue with the selector lever wiring harness cause that too?

Both issues came up at the same time, so it seems likely that they are connected. Section 307-05 of the workshop manual talks about checking for an open and a ground issue on the vehicle side of the harness, but doesn't talk about where it connects in much detail. It is up by the ignition switch in the steering column or is it around the junction box on the drivers side?

" reverse doesn't seem to work. " could be affected by worn linkage and not moving into the correct position . You never answered whether the brake lights were operating correctly .Is the interlock actuator operating / getting power ?

That makes sense. Apologies if I'm asking stupid questions :) The brake lights are operating correctly at this time, but the actuator doesn't allow moving the shifter lever - any movement at all requires using the override. I am not aware of any electronic issues. The workshop manual mentioned checking the fuses. I've replaced each with an equivalent new one.

If the cable is off enough that park on the shifter puts the transmission into neutral, would that keep the actuator from operating when the car is running and the brake pedal is pressed?

I'm going to take a look at the linkage on the transmission in the morning to see if anything isn't right.

An open circuit in the shift interlock electrical system can cause the shifter to become stuck in Park if the open circuit interrupts communications between the brake light switch or the ignition switch and the interlock solenoid.

Check for power at the shift interlock solenoid. With the ignition switch in the “ON” or “RUN” position and the brake pedal depressed, use an digital multi-meter to check for power at the solenoid. If power is present, the shifter interlock solenoid is bad.

If no power , have you checked fuses in all locations ?

I've localized the problem to the shifter cable. When I push the selector into PARK, it's still leaving the transmission in neutral. I can manually shift it into PARK using the manual lever on the drivers side of the transmission. Once I do that, the selector is able to come out of park normally. This seems to indicate that the TR sensor is involved in determining when to send power to the actuator and let it work. The workshop manual mentions the sensor as a possible cause being unable to shift from PARK, but it doesn't seem to cover this particular circumstance :)

The bushing appears to be fine, but it's hard to be certain as I was working from an awkward position with little space. When the cable is attached the manual lever, it doesn't seem to have any play if I push or pull it up and down respectively. If I try to rock the cable clip a bit, it does move (the lever stays in place) - but I wouldn't expect such motion to explain what's happening.

I'm going to see if I can get a new bushing locally (as the kit you mentioned earlier is more expensive than the replacement cable itself) and see if that helps at all. Otherwise I guess I'm looking at replacing the cable.
