It's why you should never tow an auto! Certainly can't tow/bump start them!

Actually, that's not quite correct. The BMC ADO16 1100/1300 that had the Automotive Products autobox could be towed without destroying the box; IIRC the innards were configured in some strange fashion that permitted this; possibly because the box sat in the sump and space was at a premium?
