The valve body in the Subaru CVT TR580 plays a crucial role in controlling hydraulic pressure and directing fluid flow to engage clutches and shift the transmission smoothly. It houses key components like solenoids and pressure regulators that ensure precise control of the transmission’s operation.
Common issues with the TR580 valve body include solenoid failure, which can cause harsh or delayed shifting, pressure loss, leading to slipping or erratic gear engagement, and hydraulic circuit wear, which impacts fluid flow and overall transmission performance. Symptoms of a faulty valve body include delayed engagement, shuddering, and failure to shift properly, particularly at low speeds or under load.
Repairs typically involve replacing faulty solenoids or rebuilding the valve body to restore proper fluid control. In some cases, updating the transmission control unit (TCU) software is also necessary to recalibrate the solenoids after repair.

Subaru CVT TR580 Overview:
The Subaru CVT TR580, used in models like the Impreza, Crosstrek, and Forester, is known for smooth performance but has common issues. These include torque converter shudder, delayed engagement, overheating, fluid leaks, and belt/chain slipping. Additionally, solenoid failures can cause erratic shifting, while whining noises may indicate worn internal components. Software-related issues may also lead to hesitation or jerky acceleration. Regular CVT fluid changes, avoiding heavy loads, and keeping the TCU software updated can help prevent major problems and extend the transmission’s lifespan.
