1- is the trans electronically controlled?
2- if so does it have a separate trans computer or is it controlled via the main engine ecu.
3- how are trans fault codes shown? is the powershift light on the dash?
4- how do you check engine fault codes
5- is the dash supposed to have a ecu or check engine light?
6- what does the "powershift" button do? I assumed it was the O/D switch - but is O/D locked out when its on or off?
