Shift Shock on 2005 Nissan Pathfinder

I have been experiencing a sudden shock or hesitation when shifting at 40 and 60 miles per hour in my Pathfinder. I reviewed the owner's manual and it states to turn the Over drive off during slower speeds to avoid shift shocks. Is this normal? I have been driving the vehicle since 2005 and I have 109,000 miles. Could this be a problem with the rear shock absorbers or an internal transmission problem? It is at upshifting that this occurs at 40-42 mph and it occurs at 60-62 during the upshift. It does shift fine with the OD off.

Are you talking about upshifting or down shifting or both. I also need to know, pretty exactly, what speed you are going, is it 40, 42, 45 etc and are you giving the Nissan gas or letting off? I ask all this stuff because it could be a torque converter clutch issue which comes on in a very specific way. Does your Nissan shift fine with the OD off? So, if your Nissan shifts fine with the O/D off, then it is an OD problem.
