You'll get over it...I'm still not sure what you figured out.
But I'm glad you did. Education cures ignorance.

There's also a little orange light that comes up on the dash that says "O/D off" when you push that button.

Actually this is partially true. You're od doesn't engage but your tc lockup does.
I think this is where the confusion comes. Our trannies are actually 3 speeds with a lockup converter and overdrive.
I am told you can disengage the tc but you have to dig into the pcm wiring harness.

I used to think that...until I started studying the manuals...I understand a whole lot more now than i did. Maybe only enough to be dangerous, but it least it's not some kind of "black art" any more.
Are you still haing an issue with the od or tc slippping? That could become a real issue!

When i turn my overdrive off it spikes the RPMs through all gears and keeps the truck at a higher range to make it easier for towing/accelerating with a trailer without putting too much strain on the truck. Jerrod's problem is that it doesn't do that. With the overdrive on or off it runs the same. However, that may just be how diesels are set up because the make stupid amounts of torque compared to a gas motor.
