When I am driving between 90 and 110 KM,. the tranny seems to shift out of the final gear for a second then re-engages the final gear. It does this at random and not necessarily when I am going uphill.I don't get a big jerk but do notice it. Similar to what happens when the tranny normally chages gears but in this case it is the final gear and goes back to the same gear. Any suggestions as to why it is doing this? I just have the tranny oil/filter replaced but it didn't help.
Thanks.

a tranny guy test drove my car and says it's not the tranny. He thinks it could be inadequate fuel (like a clogged fuel filter) or spark plug causing a miss. I would have thought if this was the case then it would do this when accelerating from rest. Can the "miss" occur only at cruising speed? I don't have a check engine light. Any ideas or suggestions?

It looks like the I am not getting lockup of the tranny. only occasionally it locks up then disengages the lockup and that is what I am noticing. Any ideas why I am not getting lock up?
Thanks
