So I do have an older trans in my car so that would explain why the speedo won’t work and the obd reads like 10 mph on the highway?1381-001 suggests older trans (1381-011 is newer), and the gear confirms it. I've not looked at what it takes to adapt the signal to the newer gauges.
Just wondering. Did you read all the information provided in the T45 tail shaft swap thread?could I maybe put a newer 99-01 sensor in my pcm is a 2002 btw would that make it work?
Yes I did I was looking for an easier route that didn’t have me changing the tail shaft however that seems like the way I need to go because the speed cals are no longer available. I don’t know where I will find a tail shaftJust wondering. Did you read all the information provided in the T45 tail shaft swap thread?
T-45 Tail Shaft Swap
T-45 Tail Shaft Swap
Please feel free to hit me up with any corrections I have overlooked... This write up is for the T-45 tail shaft swap. I had to change my tail shaft due to the magnetic speed sensor (found in the 99+ models) as appose to the gear driven sensor (96-98 models). Car getting the tail shaft swap...www.allfordmustangs.com
There is also a possibility that an extended range SpeedCal can change the signal to one that a 1999+ PCM can understand. A normal SpeedCal changes a new style to an older VSS style.

I have the totally wrong sensor a vss so the whole tail shaft most likely will need to be changedI had the same issue in my 99 gt manual. The speed sensor for mine was on the driver side underneath the car right where the driver seat would be. The magnetic diode gets weak over time. Usually you notice the speed needle bouncing from max speed to zero or intermittently working before it fails. 5 dollar part and it fixed mine.
