Transmission speed sensor not reading accurately

Good afternoon,

What year and model did your donor transmission come from?

I attached a picture of the speed sensor for you. If the transmission is different from the original, it will not read correctly. The sensor goes over a tone wheel inside the transmission to produce the signal for speed. If that tone ring is different, this is the result.

Thank you,
The replacement transmission came from a 2004 Ford mustang, is there a way to correct the problem?

I appreciate the help, would you be able to post the picture again but a full diagram so i can see the enitre wiring diagram?

You would need to find a speedometer guy that can fit an adapter for you to get the correct speed. The only other way is to either get the correct transmission or replace the shell inside the transmission.

That is the largest I can make it without distorting it.

I still have my original transmission, what do you mean by adapter? And where can i find someone who can assist me in this? again i really appreciate you helping it has been weeks that we have been trying to figure this out.

What part of the original transmission is the shell located?

It is internal. The transmission has to be disassembled to access the shell that holds the clutches and planetaries.

I attached a picture for you to view.

You need to do a Google search in your area for someone who does speedometer repairs.


Roy

what is a adapter? also i would need to get a 2203 transmission right?

2003 Mustang transmission will be the correct one????

Yes, did you get a 4R70 or 4R100?

I attached some possibilities for you to view. The site www.car-part.com is very good.
