PURCHASED AN 05 MAXIMA TWO MONTHS AGO.DRIVING AROUND TOWN THE TRANS SHIFTING IS WAY TOO EXCESSIVE.TURNING A CORNER AT MODERATE SPEED IT PICKS A GEAR TOO LOW THEN A SECOND LATER IT UP SHIFTS AND THEN AGAIN ALL WITHIN 20-30 YARDS.THE SHIFTS ALSO ARE ANYTHING BUT SMOOTH, THE TRANNY IS ALWAYS LOOKING FOR A SHIFT WHEN THE TORQUE WILL PULL THE WITHOUT A CHANGE. IS THIS A COMMON PROBLEM.
