System Operation
WARNING: This page is about a different variant/trim than selected.
The TCM and its input/output network controls the following operations:
- Shift timing
- Line pressure (shift feel)
This transmission is controlled by a standalone TCM. This transmission is controlled by 7 solenoids, SSA, SSB, SSC, SSD, SSE, LPC solenoid and the TCC solenoid. To control the transmission, the TCM uses inputs from the TFT sensor, TR sensor, TSS sensor and the OSS sensor. The TCM also uses engine inputs from the HS-CAN signal for gear and TCC scheduling and control.
