4. Installation and Setup

Installation of a transmission valve body is a complex procedure that requires specialized tools and automotive knowledge. It is highly recommended that installation be performed by a certified professional mechanic.

General Installation Guidelines (Professional Installation Recommended):

1. Safety First: Ensure the vehicle is securely lifted and supported. Disconnect the battery.
2. Fluid Drainage: Drain the transmission fluid completely.
3. Access: Remove the transmission pan and filter to gain access to the valve body.
4. Disconnection: Carefully disconnect all electrical connectors and remove mounting bolts securing the old valve body. Note the position of all components.
5. Removal: Gently remove the old valve body.
6. Preparation: Clean the transmission case mating surface thoroughly. Ensure no debris remains.
7. New Gaskets: Always use new gaskets for the transmission pan and any other seals disturbed during the process.
8. Installation: Carefully position the new CFTGIW AW03-72LE valve body. Secure it with the appropriate mounting bolts, tightening to manufacturer-specified torque values. Reconnect all electrical connectors.
9. Filter and Pan: Install a new transmission filter and reattach the transmission pan with a new gasket, tightening bolts to specifications.
10. Fluid Refill: Refill the transmission with the correct type and amount of transmission fluid as specified by your vehicle manufacturer.
11. System Flush (Recommended): A complete transmission fluid flush is often recommended when replacing a valve body to remove any contaminants from the system.
12. Initial Check: Start the vehicle and check for leaks. Cycle through all gear positions while stationary.
13. Test Drive: Perform a test drive to confirm proper shifting and operation. Monitor fluid levels.
