I have an 04' with AT & A/C. I'm a bit short on cash and need to replace the radiator. So I have a few questions. Do I need a radiator with AC or can I buy the one without? Will that also save me the headache of decompressing the AC system? I am also planning to add a transmission cooler so I'm not too worried about it being for a MT unless the dimensions are different. Thanks in advance.
