Ok, I'm out of idea's here. My 96 7.3 auto is still having speedo issues. It's still bouncing the needle so its also still having shifting problems. I've replaced VSS, PSOM, Speedo motor and checked the tone ring in the rear. It holds mph then loses it, it might hold it for 10 seconds at a time. It also likes certain speeds where it almost straightens up. I crawled under it again today to check wires and noticed the gear position sensor is new. Can that have anything to do with this?
Also disconnected the ABS module and that slowed the bounce but it's still there. Tried yet another known working VSS and nothing. Weirdest thing is... no codes. Nothing.
Here's a vid.
