That is a transmission code...

P1747 (EPC Shift Solenoid). Not uncommon for police interceptors...

Here is a discussion of other possible causes:

If you are trying to replace the pulley, best to remove fan (uses special tool available loan-a-tool) to gain access. Not sure, but i think the bolt is 15mm.

The police package interceptors had a common problem with the fans seizing up. There was a TSB ford released to correct the issue which called for the replacement of the electric fan assembly with an updated fan assembly.

did u check ur passin gear cable

They had a couple different alternators for that car,basically the same alternator but different regulators,might be where your trouble lies

Engine Misfire diagnosis can be complex and there are many reasons for misfires to occur. I suggest you read the article at this link that deals with engine misfires and the diagnosis of them and possible solutions to repair them.

The PCM is programed for the LS engine parameters and now that you have changed engines the signal from the new engine are out of parameters> Either see if you can get the PCM reprogrammed at a dealership or purchase a new PCM and program the chip with the police engine interceptor to the vehicle> you may also return to the place where you got the engine and purchase the PCM for the police vehicle.

I suggest that you look this up and the term interceptor refers to police package as in heavy duty suspension,brakes transmission etc. http://en.wikipedia.org/wiki/Ford_Crown_Victoria_Police_Interceptor

No start, back fires, bad compression at cylinder's.

i have ran into 2 issues in these vehicles---if it binds while sitting still also, check the steering shaft, i have found the u-joints in the shaft tighten up and binds dangerously tight---if they are free, sounds like you may have a steering box issue or restriction in a line---hope this was helpful!!
