Volvo Repair: Repalcing Volvo 850 radiator, volvo 850 wagon, leaking radiator

Question
My wife's Volvo 850 wagon (non-turbo) has a leaking radiator which needs to be replaced.  While checking out Kragen, AutoZone, etc for a replacement radiator, there seem to be different models available.  Some have are just the engine cooler, some are engine and tranny, and some are engine, tranny and oil cooler.  Which am I supposed to get?  I just assumed that the engine and tranny cooler were always part of the same radiator system, but this seems to not be the case.

Also, I saw an online procedure for removing the radiator that said it comes out the bottom.  This would require getting the front end pretty high.  Is it not possible to pull the radiator from the top as well?

Thanks,
PeterM

Answer
Peter, in a word, no.  There is no way to take it out from the top.  Your car should only have the tranny cooler lines.  Turbo models have both but just to make sure look at both sides of your rad and if there are lines going in at both sides then you have it.  Get a Nissens radiator.  Dont buy junk from Autozone.  Roger
