I was talking to Dad last night, and he told me something that he found out while driving the truck around. Put it in tow/haul, then hold the button in for 10 secs, and the tranns acts totally different. As I'm down here in college till I go home for Spring Break and get to drive the truck once again, can anyone enlighten me as to what it's doing?

Not sure about on an LBZ but if Im not mistaken, all it does is locks out Over-drive. This is what it does on the LLYs and other TCMs that have the ODLO (over-drive lock-out) feature.

Hrmm, I'll have to find out if it locks out both OD's (6spd), or just one of them.

Anyone else have any thoughts?

That's what my thought would be..mine has a second light that comes on..it is the D symbol with a line through it. I'm not sure on the 6 speeds though.

You can tap the button twice and it will lock-out the OD.
