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.
