Just wondering what you can tell me the differences are besides autotrac is push button and the manual is a shift on the floor.

With the manual, can you shift on the fly?

thanks

 

Their are design differences in the transfer cases as well. With part time 4x4 on the floor though you can "shift on the fly" at reasonable speeds.

 

i dont know how much the autotrack costs but it is a nice feature. you can hit the auto button and leave it there all winter if you want. the 4wd is there when you need it and not when you dont. it even seems to be a strong case, if you ever really start to push it 4hi works better than auto.

 

Fom an 4x4 standpoint the autotrac just has more crap to break.

For 99% of people though its a cool features like parish mentioned

 

It is a good no brainer when it works but read enough forums and you will see it is kinda trouble prone too. Firthermore personally, I like to decide when I want 4x4 not the truck. It also uses none standard fluid that is expensive to replace during changes. .

 

Trouble-prone ??....parish is putting 500+ hp through one and launching at the dragstrip in 4-hi, and I've NEVER heard of one breaking

Fluid.....it uses GM Autotrac II fluid, the same fluid that is recommended as a replacement fluid in ALL new GM tranfer cases, and it's only $4.16 a quart

 

i currently have a hd case from a 2500 but in my last truck i ran the autotrack with no problems at all. whipple at 10psi and a 100shot at the end. i was in the 500-600rwhp range.

 

I currently have an Autotrac and love it, I was just wondering if there was something signifigant about the HD case that I might want to consider.

 

i had an HD case for the 4l80e, i didn't have an autotrack that would just bolt on. the hd case is rated for twice the tq of an autotrack but no one has killed an autotrack that i know of.
