Ensure the vehicle is on a level surface and the engine is turned off.
Disconnect the battery to prevent accidental short circuits.

2. Drain Old Transmission Fluid

Tools Required: Socket set, drain pan
Remove the transmission pan bolts using a socket wrench.
Carefully lower the pan to avoid spilling fluid.
Allow the old fluid to drain completely into the drain pan.

3. Replace Transmission Filter

Remove the old transmission filter.
Install the new filter, ensuring it is seated properly.
Replace the transmission pan gasket with a new one.

4. Reinstall Transmission Pan

Tools Required: Torque wrench
Reattach the transmission pan and tighten the bolts to the manufacturer's specified torque (typically around 10-12 Nm).
Ensure the pan is sealed correctly to prevent leaks.

5. Refill Transmission Fluid

Tools Required: Funnel, new transmission fluid (check the manual for the correct type, usually Volvo ATF)
Using a funnel, refill the transmission with the recommended type of fluid.
Start the engine and allow it to warm up, then check the fluid level again, adding more if necessary.
