1999 Boxster manual transmission fluid change

[Vidyashankara]

I am due for a transmission fluid change. I looked up the diy instructions and it's relatively simple. The part I am not sure of is whether the 5 speed manual transmission also has a filter inside. Upon draining the transmission, do we also open up the oil pan and replace the gasket and the oil filter like the automatic transmission?

Thanks for your help in advance,
