problems with DT12 transmission
symptoms of the fault are:
check engine light on
amber light on
power lost
transmission not shifting right
transmission goes back to neutral
transmission fault on the dashboard
Shop talk:
ALL DT12 TRANSMISSION ARE EQUIPPED WITH A SENSOR CALLED "GEAR POSITION" THIS SENSOR IS DIRECTLY IN CONTACT WITH THE SPLIT PIN. NORMALLY, THE SPLIT PIN GETS DEBRIS AND RESIDUES FROM THE TRANSMISSION AND THIS FORCES THE PIN TO STAY IN ONE SOLID POSITION CAUSING ELECTRONIC PROBLEMS.

My DT 12 stucks from 6-7 and 7-6 in winters, but once I heat it up by idling to transmission temp above about 75 f , it gets better, above 90 f the problem completely goes away.

[@paulcarlos454]

Exactly the same for mine

Hey buddy I getting main shaft speed sensor circuit code

[@goldygill7297]

How did you fix it? I’m getting the same issue

[@alvaradoenergy3264]

Hello I have a code on my transmission SPN-521007 FMI 14. Truck does not start but as soon as we disconnect the drive shaft truck works like normal. It seems like the transmission is stuck. Do you have any tips or tricks on this issue. Thanks in Advance.
Buenas noches mira que me saco ese código SPN-521007 FMI 14. La verdad nomas se apago así de repente la troca pero una ves que desconectamos el drive shaft la troca prende bien. El problema es nomas cuando esta conectada ala transmisión. Si tienes algún tip de lo que sea o como arreglarse se te agradece. Muchas gracias.
Troca es una 2019 cascadia

No le pudieron encontrar lo que tenia, compre una usada en Felix transmissions en Dallas,TX.
Mechanic could not find what the fault was so I replaced it with a used DT12 Felix Transmission in Dallas,Tx
