I HAVE OIL IN THE RADIATOR, MY FRIENDS NEIGHBOR MECHANIC SEZ THAT SINCE I HAVE NO SMOKE AND CAR RUNS FINE, NUTHIN IN OIL OR TRANS THIS HAS TO BE PROBLEM.PLS HELP.gp1

No need to shout.

As I understand it your mechanic has diagnosed the trans cooler leaking into the coolant?.
This can be tested at your local radiator shop.

Both radiators will come with a trans cooler in the radiator tank, aftermarket coolers are normally mounted in front of the radiator.

I recommend using the heavy dury radiator, particularly if you are subjecting the car to hard use, and install an aftermarket trans cooler as well.

If it turns out the oil pipe in the radiator is not leaking you need to find out where the oil is coming from and fix it before you do severe damage to your engine or transmission.

napa doesnt list a rad with an oil cooler for your car, just the trans cooler, which is the norm. take a look at your tanks, there will be two metal lines for the trans on the pass side and some rubber lines thats likely all. its more likely you have a head gasket leak and as roger pointed out thats nothing to mess with and you should have someone that knows what they are doing look at it. not you friends neighbor

OP, using caps lock in a thread usually means shouting, and gotta admit its kinda annoying to read

easy lol considering this is his first post maybe he doesnt know yet

cant u read? i said my friends neighbor was a mechanic, i talked to him by phone. all u people do is run your mouths with nothing to say.,shutup.

wow rog that was a lot of help. never would have thought of a radiator shop.you are a genius.

Look no need to be hostile or rude we are here to help.Now if you have trans fluid in your radiator then your cooler is leaking no if and or buts...But the only way your gonna get oil in your coolant is if A it was put there or B you have bad intake gaskets but that would result in coolant in your oil as well...Also i dont appreciate you being rude.Nobody here is trying to be rude sorry if it seemed that way
