I don't think torque is an issue with the 235, I have an S10 with a 2.8, far less torquey than my 235, it turns a 700R4 just fine. I beleive that the 200 4R weighs less, and might be narrower in width, and I'm certain it costs less, but the 700 has a better first gear and is a stronger trans (GM used them in 3/4 tons trucks). Either one would be fine, although I would think the 700 would have a better in town performance due to the first gear.
