P1574 Nissan -

Question

I just replace trans does it  need to be programed

Answer 1

P1574 ASCD vehicle speed sensor

No you do not reprogram, the ASCD ( automatic speed control device), you need to find where the code originates from such as the ABS module or the TCM module, with P1574 there should be another code displayed with it, it does not code by itself.
