3rd gear???

Ok i may be completely retarded and to be honest ive never payed any attention to this but, today driving through town i shifted it down into 3rd, idk why and goin 35-40 it rides at 2500pm and increases as i go faster and wont shift down... is this because im in 3rd and theres nowhere else to shift? cuz i know on my old gasser with 35s didnt do that and i drove in 3rd all the time with it... guess i could say im confused, i swore ive driven my dmax in 3rd around town before but it doesnt rev that high... anyone???

the allison is different....it is really third gear...that is why it doesnt shift. if you want to go to only 4th gear, put in D and hold in the button on the end of the shifter....you will see a light with D and a line through it. I dont know why you would shift it into third unless you were towing heavy...if you want a little more power in town just put it in tow/haul...the rpms will be a little higher and your tranny temps will stay down since your torque converter is locked.

Alright thanks, yea i was really just curious, i never looked into it, i was just messing around and was shocked by the rpm increase, so i guess 3rd IS 3rd haha, i drove my yukon in (3) not (D)) and it was normal, so i was just curious if the duramax was the same or not, obviously it is not, but thank you for the response.
