T-case Modification?

[jman_07]

So the questions has been bugging me for a very long time with this auto-trac t-case i have on my 2002 suburban i have heard to many different stories and read so many things even on this forum.

 

I want to get it cleared up does it split the torque when it detects slip and add more torque when it needs it?? Or is it a 50/50 split in auto mode??? I have a hard time believing it is 50/50 because if i turn the wheel all the way and step on it to spin the back tires the front pulls but there is no binding like AWD

 

If it is a 50/50 split is there any modification you could do so it makes it a torque split?? besides buying the AWD t-case because they are junk i want to work with the autotrac here.

 

 

Thanks.

Anybody someone mentioned something about you can modify it to be a full-time t-case with a torque split..

I think that it splits it like 75/25 or something close to that. Maybe 65/35 sounds about right. I wouldn't know how you are going to be able to do that but good luck.

Yeah i have had Gm technicians explain it to me and tell me its a torque split so i would think its gotta be like AWD mode because i never get any binding in that mode.

 

I ask this because i know Ford Explorer has a transfer case called Control-Trac that in auto is an awd mode that splits power. when its slips.
