mate it depends if you are looking at doing a full flush or service. How many km's has your car got? If you are doing a service, drive the vehicle to warm the trans fluid. Drop the sump as there is no drain plug and let the fluid drain. Make sure you use a large drain pan. When you undo the sump make sure you drop one side only so the fluid is coming out of one side or else it will go every where. Remove the spring retainer that holds the filter and replace with a new one. Clean your sump and change the sump gasket. Reverse order to re assemble everything. Remember not to overtightn the sump bolts as they do not need a lot of torque, I think it's about 12nm. To refill you will find a plug towards the tailshaft yolk on the drivers side. Use a long hose and a funnel from the engine bay to fill with new fluid to the brim of the plug or until it starts to overflow. This should be about 4-4.5L. But before it is full, fill the the box with about two litres and then shift through your gear selector to distribute the fluid through the box. If you are looking to fully flush the box take it to a transmission shop to do for you. However if your car doesn't have many km's it is not necessary to flush. You will know once you do a service, if your oil comes out looking like crap you probably need to flush, but if it comes out nice and red then keep servicing it about every 10-15000kms. This way you are exchanging new for old fluid every time and keeping the box clean. Good luck!
