A PCM (Phase Change Material) heat sink heater plenum chamber is a component designed to enhance thermal management in heating systems. It utilizes phase change materials to absorb and store excess heat, which can then be released when needed, providing consistent temperature control. The plenum chamber facilitates the distribution of heated air, improving efficiency in heating applications. This technology is often employed in building HVAC systems and industrial processes to optimize energy use and maintain comfort.
ISC(IDLE SPEED CONTROL)ACTUATOR. the isc actuator wich is under pcm(powertrain control module) control controls the amount of air entering the intake plenum at idle.
THE PCM IS ON THE PSSENGER FIREWALL THE PCM IS ON THE PSSENGER FIREWALL
The PCM is located on the firewall in front of the driver's side. It is the vertically mounted flat aluminum box with heat sinks.
The PCM will not affect the transmission in your car. The PCM is not related to the transmission in any way.

The pcm refers to the "power control module".
You can change the PCM yourself, however the PCM needs to be programmed by a dealership service tech.
