I hope this is the right forum for this question and if not mods put it in correct forum. I went and test drove a 2500HD Dmax w/ the Ally 5-speed and I noticed that there were only 1 2 3 D on the selector. How does the 5 speed work? Does it have two OD's? Little help please.

You can engage and disengage 5th gear or OD by pushing in and holding the tow/haul switch till the no OD light comes on.

Then you are still in D which is 4th and then 3 2 1

Thanks Dragon. I'll be driving somemore tomorrow I'll give it a try.
