Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery cable for safety.

2. Fluid Change

Drain Transmission Fluid
- Locate the transmission drain plug, place a drain pan underneath, and remove the plug to drain the fluid.
- Dispose of the old fluid properly.
Replace Transmission Filter
- Remove the transmission pan by unscrewing the bolts (typically 10-12 mm).
- Carefully lower the pan to avoid damaging the gasket.
- Remove the old filter and install the new one, ensuring it is seated properly.
Clean Transmission Pan
- Clean any debris from the inside of the transmission pan.
- Inspect the magnet for metal shavings, which could indicate internal wear.
Reinstall Transmission Pan
- Apply a new gasket or sealant to the pan and reinstall it, tightening the bolts to the manufacturer's torque specification (typically around 10-12 Nm).
Refill Transmission Fluid
- Replace the drain plug and refill the transmission with the appropriate type of fluid (consult the owner’s manual for specifications).
- Start the engine and allow it to warm up, then cycle through the gears while checking the fluid level, adding as necessary.

3. Solenoid Replacement (if necessary)

Locate and Remove Solenoids
- Remove any covers obstructing access to the solenoids.
- Disconnect the electrical connectors and unbolt the solenoids.
Install New Solenoids
- Install the new solenoids by reversing the removal steps, ensuring proper torque specifications are followed.
