It controls fluid flow for smooth gear shifts and works with solenoids , sensors, and hydraulic circuits to automate shifting. Type of valve body : Your vehicle may have an electronic or hydraulic valve body, which can impact the price.

Low Transmission Fluid Your automatic transmission relies on hydraulic fluid pressure to operate. In a modern, electronically controlled automatic transmission, shift solenoids control the flow of transmission fluid. In older non-electronically controlled transmissions, shifting was controlled by shift valves, but the idea is the same.

This engages the torque converter, which uses this hydraulic pressure to shift to the correct gear. Transmission control solenoid: Regulates the pressurized hydraulic fluid (line pressure). Vehicle Sluggishness If a transmission solenoid breaks, the electronic control unit (ECU) on some vehicles may activate the “limp mode.”

Contaminated or Low Transmission Fluid Just as motor oil keeps your engine running smoothly, transmission fluid is essential for both automatic and manual transmission systems to function properly. The transmission fluid lubricates and maintains hydraulic pressure for smooth gear shifts. What’s worse? But that’s not all.

Electronic stability control (ESC) also went by another name when it was first introduced – roll-over mitigation. Both ABS and ESC use the same module to carry out corrections, the ABS hydraulic control module, or HCU. This module has three parts: the electronic module, hydraulic modulator and pump.
