Honda CR-V automatic transmission solenoid valve
The automatic transmission solenoid valve (solenoid) is an important component responsible for shifting gears in an automatic transmission. The Honda CR-V uses the following solenoid valves:
Torque Converter Lockup Valve (TCC)
* Locks the torque converter under certain conditions, increasing engine efficiency.
* Located on the automatic transmission housing.
Line pressure valve (LPCS)
* Adjusts transmission fluid pressure depending on load and driving conditions.
* Located inside the automatic transmission.
Gear shift valve
* Shifts gears by directing transmission fluid to the appropriate valve body channels.
* Located inside the automatic transmission.
Signs of faulty automatic transmission solenoid valves:
* Slipping or hard shifting
* Gear delay
* Automatic transmission related fault codes
*Transmission fluid leak
Replacing automatic transmission solenoid valves:
Replacing automatic transmission solenoid valves requires special tools and knowledge. It is generally recommended that you have a qualified mechanic perform this task.
Genuine Honda Part Numbers:
* Torque Converter Lockup Valve (TCC): 28500-PNA-A01
*Line pressure valve (LPCS): 28530-P7W-A01
* Shift Valve: Various part numbers depending on model and year.
Notes:
* Some Honda CR-V models are equipped with additional solenoid valves such as the master cylinder pressure valve (MPC) and torque converter cut-off valve (TCCU).
* Before replacing the solenoid valves, it is recommended to diagnose the automatic transmission to determine the exact cause of the malfunction.
* Always follow the manufacturer’s instructions when replacing or adjusting automatic transmission solenoid valves.
