Has anyone experienced a surging while at highway speed? It feels like a trans slip but the trans shifts fine from a dead stop to top gear. It seems to me the trans is shifting in and out of OD at highway speed after driving for awhile on the freeway, it also seems to me that OD kicks in earlier than it should as I am merging onto freeway getting up to speed it shifts fine through all the gears then hits overdrive too early and falls on its face, if i get more into the throttle it will kick down a gear as it should but then shift back into overdrive too early I think. Anyone had this issue?
I am having the same problem.. but new brake switch did not fix it for me. Any other suggestions?
I don't think it has ever done it cruising less than 50 mph. It is just on occasion on fairly level or slightly sloped road... never observed it going up hills or down. It is very brief by the time you feel it and look down to see the tach jump it's over.
