my 2001 f250 7.3l has a problem. the over drive is not working . when i press the button to turn if off nothing happens at all. i dont have any ideas to what it could be... does anybody know of any ideas to what might be wrong and any ways that i could check to see ???

 

so is the problem that your O/D cancellation button is not working? or is it actually not shifting to OD?

 

its actually not shifting into o/d
