Ford has historically had transmission issues when dinghy towing.
Have you checked the Owners Manual for towing instructions?
For some models, there is a Service Bulletin recommending adjusting the transmission fluid level for towing.
I know it is a statement that annoys many people, but please do read and follow the instructions!
