Yesterday I woke up to discover transmission fluid all under my 2006 Chrysler300 on 2006 Chrysler 300

towed in and it seems the transmission harness has failed = what is that and what would be an estimate of the cause and also a guesstimate of the repair costs?

maybe the module sprung a leak, have a shop check what is leaking first.
