Can't find anyone with the same speedometer issue
I am a mechanic but I'm not to familiar with fords. My area is imports Toyota and Nissan but I did swap my Lincoln LS for a 99 F250 5.4 V8 2wd auto tranny. Picked it up and drove to the shop, looked a bit and locked it up. Came back the next day to drive it home and clean it up previous owner let it set. Went to crank and battery was crap. Got a good charged battery fired it and took off. Get going down the road and I notice the speedo needle bouncing up until I hit 20 mph then flat line. Slowed down and it started bouncing again g.went faster and nothing. Got home pulled the sensor outs the rear axle covered in metal paste an the odd metal flake cleaned it stuck it in and test drove nothing. Went to move it the next morning and the battery is dead again. Got a brand new one and then the speedo worked until 10-15 mph. No lights no code no flashing tow haul switch. Not sure if it was related to dead battery and I don't wanna start throwing parts at it. Anyone with some insight an advice on speedo and the draining battery would be helpful. Hard to work on my stuff and still get customer vehicles out

Oh I didn't just grab it either. Wanted a 250 cuz my buddie got a 03 6.0 diesel I'd like to get a beast but the cost of fuel is outrageous so I picked a gas burner planning on getting some headers and glass packs for it, look into some cams and power chips later on, cash flow needs to increase and weather needs to get warmer to allow more work to be done, hard to work when cold wind blows under the vehicle with me!!!

I don't think this will affect your battery.
This metal paste should be looked into, though.
Re-check your sensor again, to see if it's covered in it.
Could have water in your diff, if it does.
Once thats taken care of, see if your speedo does the same.
You could also have a defective psom.
I believe the battery drain is another issue.

I am gonna pull the cover off and check out the gears today and on the way to the shop I plugged my computer into the truck and pulled up the data logger function for my nifty expensive OBD2 program and my speedometer worked and displayed 5 miles off. While on my computer it didn't show anything for the speed. Got close to the shop and it bounced a bit then flatlined. And what is psom? Not recognizing the term.

Gears are fine, paste was original break in it looks like, popped the cover off and the oil reeked of something dead. Absolutely nasty smell, fresh 80-90 and went for a drive still no speedo. Hit the dash and it worked. Need a new cluster! Awesome. Anyone got one with low miles? Or a solution to a crap speedometer? An the other thing I'm trying to figure out, my trans does not have the sensor in the tail housing, what kind of transmission have I got in it? Manufacturer date is 11/98. Might help to ring a bell.
