Transmission Management Systems

Delphi TCM8 High Feature Transmission Control Module

The Delphi TCM8 High Feature Transmission Control Module is an electronic device that assists in the control of automatic transmissions to help them operate more efficiently and more reliably. It offers a wide range of up-level features and the software can be easily tailored to meet a wide range of specific customer program requirements. Its robust design allows under-the-hood mounting, while its compact size also enables passenger compartment mounting.

The Delphi TCM8 High Feature Controller offers precise actuator control and provides manufacturers with flexibility for multiple applications. Software modifications help optimize vehicle performance while controlling both pulse width modulated and linear solenoid designs. Its high speed controller area network (CAN) communication system enables multiplexing, while flash programming provides in-vehicle memory updates.


  • Solenoid control:
    • Linear or pulse width modulated (PWM) with current feedback
  • 32-bit, 80 MHz microprocessor with up to 1.5MB integrated flash memory and 56Kb data RAM enable high-speed processing.
  • Facilitates upgrade of a manual transmission to automatic transmission without changing the engine control module.
  • Small package size uses a standard FR4 circuit board enabling mounting flexibility and manufacturing flexibility.
  • TCM8 input/output interface and hardware input/output software can be configured to meet specific customer requirements.
  • Mounting location flexibility:
    • Under-the-hood, or passenger compartment
  • Dual controller area network interface for vehicle and instrumentation communication.
  • Compact, waterproof designs allow packaging and mounting flexibility.
  • Single right angle single connector offers optimized design and increases harness and mating connection flexibility.
  • Flexibility for increased feature functions with additional low- and high-side driver capabilities available
  • CAN vehicle communication with CCP protocol for calibration instrumentation.  Keyword 2000 or LIN are also available.
  • Full-function operation capability:
    • 9 V to 16 V

Typical Applications

The Delphi TCM8 High Feature Transmission Control Module is suitable for most 4-, 5-, and 6-speed transmission programs. It can also be used to support clutch-to-clutch and free-wheeling transmission programs.

Performance Advantages
