Transmission problems

my daughter has a 2005 Chrysler minivan – v 6 automatic – the transmission will not lock in park – it free wheels – only stops moving when emergency break is applied –
the wheels will move separately – will not move the other wheel when in park – if picked up one wheel – and in park – it still moves – there is a gear that is rubbing the cover in back of transmission – the upper gear iseems loose – and wobbly – is there a simple repair there

@jcr it sounds like your parking pawl is not engaging.

Somebody familiar with your transmission would have to chime in.
