So my OD light decided to start flashing tonite. Just about a year ago I replaced the solenoid pack (Ford repalcement) along with filter and Amsoil ATF to fill it up. I hooked up my scanner tontite no codes stored or pending. The OD light will not come on until you get past 50MPH after you shut the vehicle off. Any ideas what I am looking at when I take it to the dealer on Monday?
