How should a Transmission Control Module be fitted and programmed on Volvo S80?

If a new control module is fitted, it must be programmed using dedicated Volvo test equipment, and this task should be entrusted to a Volvo dealer or a suitably-equipped specialist. The transmission control module (TCM) and the engine management ECM are located in the ECM box at the front right-hand side of the engine compartment. Begin by disconnecting the battery negative terminal and wait at least two minutes for any residual energy to dissipate from the main system relay. For four and five-speed transmissions, clean the top of the ECM box lid to prevent debris from falling inside, release the catch on the side of the ECM module box lid, and lift it off. To remove the TCM, use Volvo tool No 999 5722 or a homemade equivalent to push the top of the tool rearwards and pull the module upwards, taking care not to touch the control module terminal pins with bare hands due to the risk of static electricity. For six-speed transmissions, the TCM is located on the top of the transmission casing; remove the air cleaner assembly, disconnect the wiring plug from the TCM, undo the nut securing the selector lever to the shaft, and pull the lever upwards before removing the TCM by undoing three bolts. When refitting for four and five-speed transmissions, locate the TCM in the box, engage it with the connector, and use the tool to slide the connector rearwards before refitting the ECM box lid and reconnecting the battery negative lead. For six-speed transmissions, ensure the selector lever is in the neutral position, refit the TCM ensuring the arrows on the shaft and TCM align, tighten the retaining screws, refit the lever to the shaft, reconnect the wiring plug, refit the air cleaner assembly, and reconnect the battery negative lead.

Volvo S80 Transmission Control Module

The Volvo S80 Transmission Control Module takes control of all automatic gear changes, which provides the sedan with smooth acceleration that preserves fuel economy. The module, which is mounted on the network of electronic control units, continuously reads data from wheel speed sensors and the Volvo engine computer, and immediately chooses the optimum shift point to supply power or thrift. This Transmission Control Module contains proprietary Volvo code as well, to adjust the engine torque to the gear selection to pass confidently and cruise freely. Through thousands of calculations per minute, it also coordinates the clutch action and lockup of the torque converter so that the driver experiences smooth shifts and not jerks. The model had two general iterations in terms of lifespan. The early cars were based on a system of electronic automatic control, with the primary role of the module being to control the timing of hydraulic valves that actuate the internal clutches in the transmission. Subsequent versions added a semi-automatic mode, which allowed the driver to tap through the ratios without a physical clutch pedal and in that format the same logic unit also drove an electric clutch actuator, halting torque just long enough to allow a clean upshift or downshift. In spite of the different hardware, both versions have one objective, that of achieving a balance in performance, efficiency and quality of shift. The module uses sensor feedback to combine with pre-stored mapping and adjust in real time to the road grade, throttle position and load. In cases of unpleasant shifting, a driver may be able to perform a simple software update at the factory and have the Transmission Control Module return to factory operation, and any S80 would continue sliding like it was meant to whilst still maintaining the Volvo feel.

OEM parts are the only choice for top quality and real functionality. They pass strict checks, and they match Volvo's factory specs, so installation is easy.

Q: How should a Transmission Control Module be fitted and programmed on Volvo S80?

The transmission control module (TCM) and the engine management ECM are located in the ECM box at the front right-hand side of the engine compartment.

For four and five-speed transmissions, clean the top of the ECM box lid to prevent debris from falling inside, release the catch on the side of the ECM module box lid, and lift it off. To remove the TCM, use Volvo tool No 999 5722 or a homemade equivalent to push the top of the tool rearwards and pull the module upwards, taking care not to touch the control module terminal pins with bare hands due to the risk of static electricity. For six-speed transmissions, the TCM is located on the top of the transmission casing; remove the air cleaner assembly, disconnect the wiring plug from the TCM, undo the nut securing the selector lever to the shaft, and pull the lever upwards before removing the TCM by undoing three bolts. When refitting for four and five-speed transmissions, locate the TCM in the box, engage it with the connector, and use the tool to slide the connector rearwards before refitting the ECM box lid and reconnecting the battery negative lead. For six-speed transmissions, ensure the selector lever is in the neutral position, refit the TCM ensuring the arrows on the shaft and TCM align, tighten the retaining screws, refit the lever to the shaft, reconnect the wiring plug, refit the air cleaner assembly, and reconnect the battery negative lead.
