My tow haul switch just comes on at any given time and starts flashing. It does not turn off unless I restart my engine. Is there a fuse that I can disconnect it by? I drive a 2005 Ford 3500 cargo van for FedEx and I do alot of stop and go. Won't this hurt my tranny?

A flashing tow haul light is an indicator of a diagnostic code stored in the TCM. You need to have the codes read and find out what's wrong with it.
