I have a 2000 Accord 3 litre V6 in a desert buggy. It has the 37820-P8C-A61ECU in it. It had a bad driver affecting one cylinder confirmed with a noid light. There is no OBD port in the harness (not able to plug a scanner into system). I bought a used (working) computer off EBay. The locksmith tired to program it to match my key, but did not work. Said needs OBD port. I found a 2001 accord ECU 37820-P8C-A62 on ebay with the matching ignition and key. Is the ECU interchangable with mine? Also is there a seperate transmission ECU because my vehicle is a stick shift or a way to confirm if the ECU was for an automatic?

Any help is greatly appreciated.
