1529 is request from TCM to the PCM to illuminate the MIL...

Kinda like me calling you to turn on the lights..

You will need to gain access to the TCM to obtain the codes in the trans control module..

If you find a code for output speed sensors, test it first, there is TSB, if good, program TCM with #18..... if sensor out of range, replace sensor and program TCM with #18..

There is a couple engine programs to upde too..

Hi, I got the same code read and it came along with code P0715 which means Input speed sensor (part of the tranny). I replaced the input speed sensor (cost $80) and both codes disapeared.
