Function:
*ECM: Controls the TCM and receives signals from sensors and switches.
* TCM: Controls the solenoid valves and solenoids for gear shifting.
* Gearbox: Contains planetary gears and clutches that mechanically change the gear ratio.
* Sensors: Provide the TCM with information about rotation speed, shifter position and gear selection.
* Solenoid valves: Direct hydraulic pressure to activate clutches and brake bands.
* Solenoids: Control hydraulic pressure and flow to change gears.
Note:
*Actual diagram may vary depending on the model and year of your Honda vehicle.
*Always refer to your specific model repair manual for accurate information.
* Automatic transmission electrical work must be performed by a qualified specialist.
