Default looking for the Omighty code breaker?

93 jeep grand cherokee laredo 93 motor swapped for the 95 inline 6 with the 42re transmission. Had complete overhaul 3 months ago on both motor and trans had some issue with the overdrive and clutchconver solenoid during the overhaul we figured it had something to do with third gen tech tras had no gear at all so we went back to old solenoids and the trans worked fine till now

check engine light flashes codes 12,53,55. code 12 is battery disconnected in the last 50 cycles, code 53 pcm internal fault condition detected, code 55 end of code transmission


overdrive dash button flashes 11,24,55 Code 11 - No Engine Speed Sensor Signal, Code 24 - Overdrive Off Lamp Circuit code 55 is a end code same on check engine light.

Code in red I need explained further in depth I am figuring not everything is going to crap out all a once. I figure one of these is the source of the problem.

New development now when i turn the key forward I get not power. Checked battery voltage and it reads 12.8v but no power to anything else checked for blown fuses and all fuses are good. I am going to have to say bad PCM/ECC. Any input?
