ZF6 Issue

i just bought a 2006 f250 with the zf6 in it. the trans feels quite notchy going into gears and it like to be rev matched for the gears to engage very smooth, otherwise you gotta give it a little pressure to go in. now the trucks only got 65,000m on it and it was quite well maintained also.

i was wondering if this is just normal for these trans or if theres a way to fix it, almost seems like the clutch is dragging but im pretty sure its not, kinda the same symptoms.

i figure a fluid change might help it some but im not sure what to use, i kno ford says mercon atf but im thinking a sythetic gear lube might help smooth it out some so if anyones got any opinons on this issue id appreciate it.

and i tryed looking all over the internet and this site but no one seems to have a definitive answer to this...
