Does a replacement PCM need to be programmed?
PERFORMANCE REPROGRAMMING A PCM Reprogramming is usually required after installing an aftermarket performance cam, bigger cylinder heads, a different intake manifold or fuel induction system to compensate for changes in airflow.
What does resetting the PCM do?
When the PCM (Powertrain Control Module) is not working properly, the vehicle will have problems such as warning lights displaying on the dashboard or even stalling and sputtering. Resetting the PCM on your vehicle will help to clear all codes from it after a problem is fixed.
What happens if you don’t reprogram transmission?
If your computer needs reprogramming or rebooting, your transmission may start acting up. Automatic transmissions are tied to sensors and solenoids that communicate with your car’s computer. As the bands and clutches in the transmission wear out, this communication can break down.

Do you need to reprogram the OBD-2 computer?
As rear wheel drive technology began to merge with front wheel drive systems, the transmission controls migrated to the powertrain control module (PCM). With the exception of the RE and RH units, all of the PCMs can, and should, be quick learned. Most of the OBD-II computers have programming update capability.
