today when starting his escape, my boy found that the automatic gear shifter does nothing. you put the brake on, and the lever can go to any gear but the transmission actually doesn't do anything (ie it just stays in park).

i think the transmission shift cable has broken or somehow became disconnected. it is being towed to a repair shop in the morning.

how easy or hard is it to repair/replace/reconnect this cable? any estimated cost?

finally, could it be something else? if so, what would be your best guess?
