When my transmission goes into overdrive, transmission slips like it is in neutral. 1st, 2nd, and 3rd are o.k. If I shut off overdrive truck runs fine. Is this a transmission problem or is it something with a switch or computer issue ??

Hey FORDQUESTION0785,

It sounds like you could have a pressure control solenoid that may be out. Here are instructions and diagrams below to show you how to replace it, if this does not work then there is a chance the transmission is going out and needs a rebuild or replacement. I would recommend a service but it is too late for that, the overdrive clutches are burned up.

If so here is a video on how to remove the transmission on a similar vehicle so you can get a rebuilt unit.
