Chevy & GMC Vans

Just got a 98 awd and was wondering if the traction control/abs was the same as my 2000 When a wheel begins to spin on my 2000 awd the abs would flutter it with brake which was hugely beneficial on ice or deep snow and was wondering if the 98 had the same thing If not is there a way to make it the same?

'97 and up have the same electronic AWD system, but I'm pretty sure it's not traction control as you describe. It sends power to the front wheels, but no brake application. As far as I know the ABS system is separate (although, it may share same sensor input).

it didn't change to electronic transfer case till 1999

aaaah so what I was feeling when a tire began to slip was the transfer case redistributing power? It sure felt like the abs my concern is taking the 98 into deep snow and end up with one front tire spinning and one rear tire spinning Is the 98 awd less capable than the 2000 awd in the snow? Any input would be appreciated

Oops. Thanks Cobra.

I believe the pre-'99 TC's are mechanical and engaged full-time, whereas s the post-'99 TC's are electronic, engaging only when rear wheel slip is sensed. So you get better fuel economy, and some say, behaves better in the snow because the torque to the front wheels is feathered by a clutch.

I have a 1999 and a 1994 AWD, and I couldn't really tell any difference between them in the snow, other than the 1999 has a G80 and that would make the rear step out when pushed hard in deep snow.

I have no experience with the electronic cases, but it's tough to fault the viscous clutch case in the snow. Traction to the front is near instantaneous since the case runs a 40/60 (front/rear) split under normal conditions and goes to 50/50 when traction dictates.
