Valve Body

Supply of remanufactured parts

Valve Body

An automatic hydraulic control that supplies oil pressure to the clutch and torque converter of an automatic transmission, allowing it to shift automatically to match the vehicle's speed.

Role and Structure

An automatic hydraulic control that supplies oil pressure to the clutch and torque converter of an automatic transmission, allowing it to shift automatically to match the vehicle's speed. It consists of solenoids, hydraulic valves, springs, and valve blocks.

Failure Symptoms

Debris from the friction clutch sticks to the solenoid or hydraulic valve, preventing smooth hydraulic pressure to the clutch, or damage to the solenoid or hydraulic valve, causing shock or slippage when shifting.

  • Jerks or slips when shifting while driving
  • Transmission warning light turns on (cogwheel symbol or engine warning light)
  • Hard to drive at high speed but the RPM increases
