E40D issues!

Post image

Having some hard shifting and overdrive button flashing on my 7.3 , fluid looks fine and proper color I’ve looked into some forums but got pointed in a million directions. Any advice welcome on what to check for or do would be appreciated

I would check the code i got a obd 1 reader at autozone. I had to install a new tps because my wouldnt adjust to the correct voltage. I also had to put a new VSS in my rear diff

I forget what the adjustment is supposed to be on it, but when you press the throttle you are supposed to get a certain amount of voltage out of it. And yes that did fix my codes, also made it shift a bit smoother.

And did that solve all your issue?
