Magnum V6-2.7L VIN T (2007)
Control of the transmission is accomplished by fully adaptive electronics. Optimum shift scheduling is accomplished through continuous real-time sensor
feedback information provided to the Transmission Control Module (TCM) portion of the Powertrain Control Module (PCM).
The TCM is the heart of the electronic control system and relies on information from various direct and indirect inputs (sensors, switches, etc.) to
determine driver demand and vehicle operating conditions. With this information, the TCM can calculate and perform timely and quality shifts through
various output or control devices (solenoid pack, transmission control relay, etc.).
The TCM also performs certain self-diagnostic functions and provides comprehensive information (sensor data, DTC's, etc.) which is helpful in proper
diagnosis and repair. This information can be viewed with the scan tool.
TRANSMISSION IDENTIFICATION
The 42RLE transmission can be identified by a barcode label that is affixed to the upper left area of the bellhousing.
The label contains a series of digits that can be translated into useful information such as transmission part number (10), date of manufacture (4, 5),
manufacturing origin (2), assembly line identifier (6), build sequence number (7), etc.
If the tag is not legible or is missing, the "PK" number, which is stamped into the left rear flange of the transmission case, can be referred to for
identification. The entire part number, build code, and sequence number are stamped into the flange.
