CompG Radiator Different?

[Aeroheadcww]

I was looking on RockAuto at radiators and noticed that the AC delco radiator has two listed for the GTP, one with the WS6 package and one without it. IIRC the WS6 is the CompG. I looked at GMPartsdirect and they showed the same thing. Anybody know the difference? The price is about twice as much. I'm thinking that maybe it had a different tranny cooler in it due to the TAP Shift. I was weighing my options on replacing it since I am replacing a failed transmission, but I can't afford a $350 radiator, I'll just put an external cooler on or try to have it flushed, maybe both.

WS6 is the compg package, but the package doesn't specify radiator from what I see. It very well could be larger. You don't necessarily need a delco radiator, though. You can measure yours and buy one of the same size. Can check in with local part stores. ZZP sells a 1.4" radiator for $300. I think their old radiator offering was a specrte 1.25". I think normal gtp is... .875"? Likely the compg would be 1.25" I guess.
