I just bought this truck a week ago. I had to put an alternator on, and changed the glow-plug controller. Now it has the P0708 code. I have read some of the other forums and it is mentioning the nsbu switch. I am starting to think that is the problem. I am want to make sure before I spend 225 dollars on the part.

This is a Allison OEM? should of started a thread there. How to http://www.dieselplace.com/forum/showthread.php?t=338137&highlight=P0708

I appreciate the response. I changed out the switch and everything is working great.
