just picked up a v70 t5 with about 220k miles and its super weird to get it into 5th. coming out of 4th 100% of the time i cannot shift into 5th first try, i usually press where it should go, let off and press right back again and it goes in. sometimes this requires a little playing with, never more than 4 or 5 tries. i have had 2 different (competent) drivers test and confirm, so its not just me. any help?

P.S. its the m56h trans
edit-just discovered pumping the clutch solves this, so im guessing master/slave leaking?
