2010 xc 90 T6 hard shifts

[raquette]

well replaced the serpentine belt and idler that had a bearing set up last weekend. That is an interesting project since the air conditioning compressor AND the power steering pump must be removed to install the belt.

the xc90 with 104k miles occasionally has a hard shift. replaced the trans fluid with no change. have read about this is common on some older xc90's and a reflash of the computer may help. I guess that is the next step to diagnose the problem.

with those that have this year and same hard shift problem, what has been the remedy?
