Will doing the ABS mod effect my traction control?
if you are talking about the "Option B" mod, then no. you will still have fully functioning ABS, TC and Down Hill Control. assuming, of course, your issue isn't related to speed sensors.

Option B will enable the traction control to work properly. If you have the Boys from South of the Border due to the shuttle valve switch failure traction control and hill descent control are disabled, according to the RAVE.

Have you had the ABS codes read to confirm where the problem is?

I cant remember what the codes were. my downhill descent still works fine and I can hear the traction control buzzing and the light comes on at the dash... does that mean its not working? I only ask because I was going up hill and the rear was not spinning at all. With the diff locked and 4lo.
