Since no else has chimed in, I'll try to help. As you mentioned, the 95 is OBD, and the 96 and newer are OBD-II. As far as I know, this means that these are different computers. I also believe that the mtx PCM is different from the atx computer. Maybe someone else will either confirm or deny.



I confirm, you must have a 95 PCM that match your transmission (ATX or MTX).

Make sure you don't have a problem to communicate with the PCM before pointing to it as the problem.

When you replace the PCM, you have to take the information from the old one, with the NGS or the WDS ( your friend should know these) and then replace the PCM, and download the infos in the new one.
