Remove the transmission pan by unscrewing the bolts (ensure to have a new gasket ready).
Take out the old transmission filter and replace it with a new one.
Clean the transmission pan thoroughly and allow it to dry.

4. Install New Gasket and Pan

Place the new gasket on the cleaned transmission pan.
Reinstall the transmission pan and torque the bolts to the specified manufacturer’s torque setting.

5. Refill with New Transmission Fluid

Using a funnel, refill the transmission with the correct type and amount of new transmission fluid as per the manufacturer’s specifications.
Start the engine and cycle through the gears to allow new fluid to circulate.
