Dear Scott, I just bought a 1997 Honda Civic DX coupe from my father.   It is automatic transmission.  It has 183xxx miles. It is showing code p0700 which is a transmission related issue. My father is a mechanic not the best but he does everything. He only has a 20 year old craftsman scanner tool, so he cant see if its the tranny the ecu or the tranny sensors. He went to pick your part today and found a 2000 civic ex with a good clean tranny with clean oil. He bought all the automatic transmission sensors but are the vtech ex cars tranny sensors compatible with a DX non vtech tranny?  I know this generation of civic from 1996 to 2000 got a face lift in 98 or 99 with different lights gold fenders and bumpers.  If it is the ecu, since the TCM is in the ecu in this car.  I assume the car we pull the ecu from at the pick your part would have to be a DX or lx right? Since ex si and others have different engine I assume ecu changes too.  What year and base trim level can I pull ecu from for my 1997 honda civic DX coupe?
