2. Inspect and Replace Shift Solenoid A

Remove Transmission Pan
- Use a socket set to remove the bolts securing the transmission pan.
- Carefully lower the pan and drain the transmission fluid into a suitable container.
- Clean the transmission pan and magnet inside for debris.
Access Shift Solenoid A
- Locate the shift solenoid A within the valve body.
- Remove any retaining clips or bolts holding the solenoid in place.
Remove and Replace Solenoid
- Disconnect the electrical connector from the solenoid.
- Pull the old solenoid out and replace it with the new one.
- Reconnect the electrical connector securely.

3. Reassemble and Refill

Reinstall Transmission Pan
- Apply a new gasket or sealant to the transmission pan.
- Reattach the pan and tighten the bolts to the manufacturer’s specifications using a torque wrench.
Refill Transmission Fluid
