F-150 ov erdrive
I have a 1999 F-150 4X4 a couple of days ago I was driving along and was in overdrive as I started to push throttle down it started to buck, and has been doing it on and off, but when I get out of overdrive it seems to be fine, is there a overdrive sensor.

First thank all of you for your replies, one COP and 8 platinum plugs were changed less then a year ago, now when I first start it up in the morning t runs fine, but after it warms up it and I stop then start it again it runs rough until I get to 35 MPH then mellows out, I put my code reader on truck several times but NO codes, I took it to a local auto repair shop and they said that I should change #4 cop, but if it was bad wouldn't it show up on reader, when asked what there reader said I got no answer. Any more help would most appreciated.
