The Shifter of my van does not move into R or D, is transmission problem?

Chrysler Recalls 2001-2002 Dodge Models Because Park Shift Interlock System May Fail (RepairPal Expert Overview) Chrysler is recalling certain 2001-2002 Dodge Dakota, Durango, Ram 1500, Ram 2500, and Ram 3500 models because the park shift interlock system may not function correctly. When this system fails, the shifter can be moved out of the "Park" position with the ignition in the "lock" position. The ignition key can also be removed when the shifter is not in the "Park" position. Either of these conditions could allow the vehicle to roll away unexpectedly, possibly resulting in a crash. Dealers will replace the gearshift blocker and bracket assembly.
