P0700 is a general trans code, thrown by the PCM when the TCM side has a code in it for the trans.
The P1751 was a code for a malfunction in the shift solenoid B hydraulic circuit.
P0780 was a shift error of some sort.
P0739 is fairly common, and a code that says the pressure switch didn't close when the 3rd gear shift occurred. The MIL will come on, but the trans will still operate.
You can't do anything regarding the PCM if they want to change it, there is no plug and play, as the PCM has to be programmed to your keys. (all of them)
Wherever you were bringing the car, obviously doesn't know Honda autos very well. These units are not ones that are cheap or easy to properly to make work right. The unit should have been sent back as a core for a reman from a Honda authorized rebuilder. I doubt you'd be having the same problems over and over.
