skipping shifting... on 2004 BMW X5

When traveling from 30 to 50, the transmission acts like it wants to shift, but only (hiccups). Any ideas?

It is best to have a transmission shop or garage familiar with BMW vehicles check out this problem to determine if is transmission mechanical, transmission electrical, or even engine related. BMW do have a Service Bulletin SI B 24 13 07 regarding poor electrical connection at a main transmission electrical connector.
