my dads truck (93 f350 7.3 E40D hypermax turbo) keeps jumping the rpm up by like a couple hundred rpm or so, only does it when its in overdrive. when he told me about it I thought maybe it just kept shifting out of OD but after driving it myself it isn't shifting, its just jumping up the RPM and then dropping it again for some reason. any ideas why its doing this?
here Is a video of what its doing, kinda hard to hear but you can hear the engine kick up and then drop back down.
it does it worse at higher speeds too, It was just easier to get the video on a back road at slower speed with less traffic.
