Okay I'm at work at crapa auto parts and apparently I'm the diesel expert. :rolleyes:

I need some help figuring this one out. This guy needs a new ECM, its a '94 and he says it has an electronic pump. He's driving it in here for me to take a looksey but the only thing I've seen similar to this is the controller for a mechanical pump for the trans. the truck is an auto btw.

That number is for a 91-93 TCM . The 94 and up is 16196390 and yes that is for the 4L80E trans .
