Powertrain Control Module
WARNING: This page is about a different car, the 2002 Mazda 626 and 2001 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
The PCM receives inputs from various engine or vehicle sensors and driver demands to control shift scheduling, shift feel and Torque Converter Clutch (TCC) operation. The PCM has an adaptive learn strategy to electronically control the transaxle which will automatically adjust the shift feel. The first few hundred miles of operation of the transaxle may have abrupt shifting. This is a normal operation. If the battery has been disconnected for any reason, it will need to be kept disconnected for approximately 20 minutes to reset the adaptive shift pressure strategy or the scan tool should be used to clear the transaxle keep alive memory (KAM) tables. PCM is located in center of instrument panel. See Fig 1.
