I AM CHANGING MY FROM STANDARD SHIFT TO AUTOMATIC. DO I HAVE TO CHANGE THE ECU AND HARNESS?

1985 Mazda RX7 • 4 cylinder Manual •

When I install the transmission will I have to change the ECU and the ECU wiring harness? Can I use the standard shift ecu wiring harness? Are there any other sensors or electronic parts that are different on an automatic car?

We only recommend direct fit parts. As far as this is concerned, everything that is related to the transmission will need changed to comply with the different trans.
