GA8G45AW Automatic Transmission Valve Body Assembly 24338744991 For BMW X1 F48 With Single Oil Temperature Sensor Version

The GA8G45AW automatic transmission valve body assembly is a critical hydraulic control component, managing gear shifts and clutch application via precision solenoid valves and fluid passages. Key features:

1. Hydraulic Control – Directs ATF flow to clutches/bands for smooth shifts.

2. Solenoid Valves – Electronically controlled (PWM or ON/OFF) for precise pressure regulation.

3. Valve Block – Houses spool valves and check balls for flow direction.

4. Pressure Regulation – Modulates line pressure via the pressure control solenoid (PCS).

5. Common Issues – Sticking valves, solenoid wear, or clogged passages causing harsh shifts or slippage.
