TCM or ABS Module or both?

CHEVROLET VENTURE

I have a 1998 Chevy Venture minivan 3.4l 6cyl FWD with 123k miles. The positraction no longer works. I have had two different opinions on what may be wrong. One GM dealer says the Traction Control Module needs to be replaced and will cost about $1300 including labor to fix. Another mechanic who has worked on GM cars says its the ABS module that is bad(controls the traction control) and will cost under $400 to replace. Is either or both correct? Does the 1998 Venture have both kinds of modules?
I don't want to get ripped off, but I would like to have an honest answer from someone knowledgable with this type of vehicle.

Thanks very much for your help.

Your van has both they are located in front of the gas tank. Should be a silver cover protecting them. Also they connect to each wheel sensor could be a blowed relay, fuse broke or chewed on wire[ puppies love to chew where they curve] do the abs/tcm lights work in the dash? I backed mine up on a set of ramps and found a chewed wire on mine. Just go up under it and look around. If your going to work on get yourself a haynes manual your make and year as it has wiring diagrams in it. Where as chilton not as much wiring diagrams
