You didn't say what kind of truck you have, or if you know about the Doug Nash unit. So please excuse me if I sound like a know-it-all. I'm not, believe me. The dne2 is an overdrive that installs behind the tranny- in place of the tail stock on the tranny and hooks up to the drive shaft. It's electrically controlled by a toggle switch in the cab of the truck. The switch engages or disengages the overdrive thru a solenoid that slides a fork for engaging.
Anyway- could the overdrive be partially engaged?
