Where are the solenoids located in a transmission?
The opening and closing of the solenoids is controlled electronically by the vehicle’s Engine Control Module (ECM) or Transmission Control Module (TCM), depending on the vehicle. A modern-day transmission uses solenoids to engage and shift gears, called shift solenoids, which are normally mounted to the transmission valve body.
How much does a transmission solenoid pack cost?
