what year is the truck? does the odometer
work? check engine light on? post codes.August 16, 2013 at 8:28 pm #539532Odometer works, 2001 ford XLT 4.6 engine have changed the trans speed sensor and have taken the cluster apart too. All that stuff in there is solid state how would that go bad? But everything goes bad sooner are later. I wonder if a person can take the speedometer out of a junkyard one, you still would have your mileage.
Talk to me let me know what you think>>>August 16, 2013 at 9:34 pm #539538No chech engine light no codes
August 17, 2013 at 1:13 am #539549does this truck have the sensor on the rear diff on the top?

MJB here.
August 17, 2013 at 3:53 am #539564with a scan tool.see if when you read live data you can
see the vehicle speed. if you can replace the cluster with
a salvage unit. if not seen wiring issue.August 17, 2013 at 7:04 pm #539607Collage Man I thank you for your interest but all I have is a ohm meter. This is what I am going to do
next. I will take the front gages off and see if I am getting any volts there is four pins that control the speed (not ask me how)but I’ll let you know what I get out of it.
Can Eric help me in this I have only been a member for four days.
Collage man is there a way I can contact Eric the car guy.
August 18, 2013 at 2:57 am #539674You can Private Message (PM) Eric, but 98% of all questions people have are usually appropriately answered and diagnosed well by College guy, Wysetech and Wrench turner. ETCG only gets on here and posts once a week or so, so maybe he will address this…
What College guy is telling you is good start… Ensure the ECM is getting the proper speed from the sensor…. Yes or no here changes where you have to look next.
You can get a decent scanner at HF for around $60 with a coupon… This will give you the live data…and a powerful tool for a long time… Without it, a proper diagnosis is much more difficult.
I wish you luck with your diagnosis technique…

Eric is on vacation. I will leave him a message.
August 18, 2013 at 3:53 am #539682August 18, 2013 at 6:47 pm #539722This is MJB thought I would give you all an update of how things are going, for people that might have the same problem as I.
I have checked the voltage on the tach and speedometer the tach checks 1.2 to 1.6 volts the speedometer checks 1.5 to 1.7 but one pin checks 10.3 volts so what I am Going to do is get a junkyard cluster take the motor out of it and see if that works. But first I’ll see if the junkyard one works in my truck.I’ll let you all know what comes of it.
The reason why I did not use a service manual is I am a retired machinist and have NO money to spare.But I do keep up with the truck and car repairs.
See all you good people soon…August 18, 2013 at 8:23 pm #539725I think you’re on the right track. If the odometer works then the cluster must be getting a signal from the speed sensor.
