Xsara picasso 1.6 NFV engine 2003 70kw gearbox

Hy can I know somehow what kind of gearbox my car have inside ?

My gearbox is still working but the second shift is does not operate so good :/

I would like to buy an other one but I can not see the number on it

I figured out 20DM64 or 20dm66 is possible but I'm not sure

Or they are fit maybe both on the car ?
