I have pretty good seapage which appears to be coming from the passenger side at the bottom of the radiator or around that general area. What would this be an indication of?

Where is coming from raditor or oil pan

Touch the seepage with a paper towel and look for the green color.

On the passenger side you have transmission cooler lines, a coolant level sensor and the side housing of the radiator.

If the radiator plastic looks cracked where the seepage is, it'll be time for a new one or new endcaps on your current one.

If the fluid is red, that'* a transmission line leak.

If the leak is at the electrical connector then you probably need to pull your sensor and check the seal.

Thanks for the fast response. Will check those items and see if I can find the problem. Don't think it is from the oil pan because there is a lot of oil coating the undercarriage right at the front where the plastic piece that covers the AC compressor is. The oilpan has a lot of oil on it, but I think it'* from blowback. Does not look like transmission fluid, more like motor oil.

Upon furthur review, did the paper towel check, fluid was red. IMMEDIATLEY checked transmision fluid, was about a quart low. Could this be some thing as simple as a loose connection at the transmission cooler? Had transmission replaced about this time last year. If it is a bad line, about how much to replace. Thanks in advance for all your advice!!!

It could be a loose transmission line, but it is probably a rusted line. I've had that problem twice, most recently when I replaced my rad (all the twisting caused the rusted line to rupture).

Lines are pretty easy to replace, and they're not too expensive at the dealer.

that isnt one of the lines that was recalled by pontiac due to it breaking and leaking and catching on fire? is it?

Ok guys, what I have is a leaking line from the tranny cooler. Lines are corroded and need replacing and there is a slight leak in the tranny cooler itself. I took it back to where I had my tranny rebuilt and the guy told me he will replace the entire tranny cooler for $129.00. He also said when he does it he will bypass the radiator and run the lines straight to the cooler. Two questions. Is this a good deal and is the bypass he is talking about ok and will not damage the tranny? Thanks in advance for all your help.

Any one??
