The OBDSTAR TCM-023 is an adapter cable featuring a 58-pin connector on the vehicle side for the transmission control module and a 15-pin DB15 connector on the device side. The 58-pin side connects directly to the original TCM connector of the ZF 9HP automatic gearbox, whose control unit is typically mounted internally within the transmission; the vehicle's OBD2 port remains unused.
The ZF 9HP is a nine-speed automatic transmission deployed under licence by various manufacturers; in Stellantis models, the same transmission carries the licensed designation Chrysler 948TE. Its proprietary, highly-pinned TCM connection enables bench programming: the diagnostic system bypasses the vehicle network and communicates directly with the control unit. This allows software data to be read and written even when vehicle network communication fails—for example, with a faulty or non-responsive TCM. The cable provides access to this transmission control module only. Which operations are actually possible depends on the connected OBDSTAR device and its software support; the cable itself adds no additional vehicle coverage. For bench use, the TCM must also be supplied with separate power and ground connections.
ADVANTAGES
CONSIDERATIONS
Applications and capabilities
The TCM-023 establishes a bench connection between a ZF 9HP transmission control module and the DB15 port of your OBDSTAR device.
Control units you can access
- ZF 9HP transmission control module: The nine-speed automatic TCM via the original 58-pin connector.
- Non-communicating unit: Even a faulty or silent TCM remains accessible via this method, independently of the vehicle network.
What you can do
- Read TCM data: Retrieve current software content and configuration data through the 58-pin connection, independent of the vehicle network.
- Write TCM software: Write modified or replacement software, for example when replacing the control unit or performing a software update.
- Identify TCM: Read hardware version, software version and calibration identifiers for verification before or after a programming operation.
- Perform bench programming: Access and programme the unit outside the vehicle, even if the control module is non-communicating.
- Note: The functions listed are only available if the connected OBDSTAR device supports them; the cable provides the connection only.
