3x3x5 Parity help

[Youssif]

hi
need help with parity on Clavin 3x3x5 Cuboid
i solve the bottom 4 layers first, then solve the last layer using 3x3x2 Pll's
sometimes in the 2nd layer i get 2 centers swapped but the middle layer is solved, so when i fix them the middle layer gets parity, when i fix it, the 2 centers gets swapped again.
How do i fix this?

Perhaps you should try to do a 3 cycle, rather than a 2 cycle?

if you know U2 , you could use it to swap those 2 centers , like on a normal 4x4

I assume blue is opposite of green, and the blue face has 1 green on it, just opposite of that single blue in the green face. If you have the situation as in the picture you posted...

Hold the yellow face on front, and do the lowercase letters as slice moves:

Setup: d R2 d'

Replace one blue center on the L-face with another blue center: L2 u M2 u'

Replace the green center on L-face with a blue center: L2 u M2 u'

Undo setup: d R2 d'

Then learn commutators: http://www.youtube.com/watch?v=54SGrZbLcoE
