2000 Exp Has 15 Error Codes

Hi My 2000 Expedition has 15 error codes going on all at the same time.

It started with the Transmission going down , the check engine light came on and the overdrive light started blinking. I have 67,000 miles on the truck.

Anyone have any Ideas what could be causing this?

thanks

Mark
