Hi guys I have a 2004 gtp that I'm replacing the radiator on. I ordered a spectra radiator off rock auto that is supposed to fit, part #cu2862, however the fittings for where the trans cooler lines go in are too small. The trans cooler lines themselves are larger than the openings on the radiator so it looks like I will have to order a different one. I ordered the spectra because it has a 1" core vs the 5/8" the stock size. My question is are there different trans cooler line sizes? Since mine doesn't have the ws6 package would I run into the same problem if I ordered the acdelco one with the ws6 package since it has a thicker core?
