sorry for the confusion let me start again

my cl starts and drives (its a automatic) and while driving it will kick it self into neutral
befor it does that the tranny shifts perfect all gears work but when it messes up no gears work . if i turn car off and put it in drive again it will go but also sometimes when i put it in drive it wont go but if i change it to another lower drive like 1 or 2 it will go after that when its going you can put if in regular gear and it will work until it messes up ..
it ran a pcm code saying the pcm faulted . i got a ecu off of ebay from a 2002 cl but it didnt even start my car when i installed it the ecu was a pge-a57 the factory one from my car is a pge-315 i wanted to know if the a57 would work like how p28 and pr4 ecu would start civic /integras because i was wondering if the ecu that i got off ebay was bad ? or i needed a pge-315 b/c thats what it had in it
