Sounds like her bush was damaged. Linkage hasn't dropped out but there's looseness when selecting gears. When slotted into what appears to be D, she must have remained in N. When in N, engine will only rev to 3K. Only need to glance at the meter cluster to see which gear is engaged.
I believe the bush on it's own, is tough enough for normal usage. Problem arise when starting the car's with a weal battery, you may hear tak tak tak sound from the gear selector. I suspect the voltage dip caused locking solenoid to temporarily seize up. So, some people managed to start the engine but couldn't move out of P. Hence in their alarm, resorted to 2 handed pull to move out from P. It's more of a solenoid issue rather than the bush
Solenoid seize may be resolved by stopping the engine and unplugging the car's battery for several seconds.
