This might've been answered, but i suck at searching.

I realised recently that i've changed gears it seems harder to change into, especially 1 and reverse, I've never had this problem before while driving;

before it use to just slide into gears, now i have to apply extra force.


What i think might affect it so far is the manual transmission fluid, as its due for a change, as well as engine oil, could it be one of these two or otherwise?
