Anyone know how to keep the allison out of OD? 5spd. I may lift eventually and i dont want to be running 5th gear....why couldnt they just put 4th on the column instead of 3rd!

Hold down the tow/haul button for a few seconds. You'll see the OD off symbol when it locks out OD.

And this goes for a 2002 ?

does it show a a od off symbol on your gear shifter?

go to kennedy diesel he has all the instruction for what u want 02 does not have this stock

I looked on that site but it wasnt under the transmission stuff.

Also, take a few minutes to fill out your signature. It will help people give you the correct answer the first time if we know what you have.

Damn, looks complicated. Does anyone sell a kit with everything included? And im sure this will work with the 8.1
