The torque converter and shift control solenoids in an automatic transmission are typically located in the following locations:
Torque converter:
* Inside the torque converter
Gear shift control:
* Solenoid Control Unit (SCU): An external module, usually located in or near the transmission pan.
* Automatic transmission housing: Inside the housing where the valve plate and pistons are installed.
Typical solenoid placement:
* Torque converter lock-up solenoid: In the torque converter.
* Shift solenoids: In the automatic transmission housing, next to the corresponding shift pistons.
* Mode shift solenoid (P-N-R-D): In the automatic transmission housing, next to the mode selection piston.
* Pressure relief solenoid: In the automatic transmission housing, relieves pressure in the gear shift circuits.
* Pressure solenoid: In the automatic transmission housing, adjusts the hydraulic fluid pressure in the gear shift circuits.
Note: Solenoid locations may vary depending on transmission design. Refer to your automatic transmission service manual for specific information.
