If you have trans fluid in your coolant, about the only place that could happen is the the radiator. Get a new radiator.
Unless you suspect someone put trans fluid in your coolant. That sounds like it would be unlikely.

This seems to be an issue in 03-08 pilots as well, my wife's 05 pilot radiator had a leak last year and I replaced it but if you read their forums http://www.piloteers.org/forums/69-2...ance-100k.html people are replacing them at 100k miles because they have the tendency to split internally and have your trans fluid and coolant mix and kill the transmission

WOW, talk about a step backwards in quality... my 20 year old accord radiator is still good and the 12 year old CL-S one is still good

I believe that there is a heat exchanger between coolant and transmission up under the air tube?

no heat exchanger in the rad on 04TL it is on top of the transmission as indicated in the above pix (E15-10). The lines come off of the engine around the TB area

On the '04-'06, the heat exchanger sits on top of the transmission instead of being built into the radiator. Same thing, one brings coolant to the heat exchanger, one brings ATF to the exchanger in the radiator. When they leak you get the same result. ATF gets into the coolant while driving. When the engine is shut off, coolant gets into the transmission.
Coolant is extremely bad for the clutches in the AT. If it's not ruined already it will be shortly. Replace the exchanger, flush the transmission, and flush the cooling system.

I wouldnt replace the radiator just yet....
drain all the coolant...replace with any cheap coolant...run the car for a little bit and let the coolant run through the system....replace the coolant again...
I would do this twice and then finally run Acura Type II coolant....if all runs good, cool, else then I would replace the radiator...

^ why would he replace the rad? it is not possible for coolant to get into the trans fluid or vice versa from the rad. the exchanger on the 04TL is in the exact same place as the 01-03 TL/CL-S right on top of the transmission.
To replace it you have to (in a nut shell):
Remove upper air box
Remove intake tube
Disconnect the cooling lines from the big round circle thing (#1) and point them so that coolant cannot enter the top of the transmission.
Install new heat exchanger (#1) and make sure you place the seals (#2) on correctly and do not over torque
Reconnect cooling lines
Reconnect intake tube
Reconnect upper air box
Bleed system
Done

^^^ do you even read mah man?
all the posts above me (2,3,4,5,7) asked to replace the radiator...again am not sure what ATF does to the seals/etc or it might be stuck in the rad...hence suggested to flush the coolant couple times and if it leaks/etc then replace it...

To flush I would use half distilled water and half of the 50-50 Type II mix. This will give enough protection and lube for the water pump but not waste too much coolant. Only do this if temps stay above freezing. 170-200 degree water will clean the block, heads, and radiator just fine. I would run it for a day and drain it while warm. I would repeat until there's no more visible oil in the coolant. Transmission is top priority though. Drain and fill, start and idle for 5 minutes and drain and fill again and use the usual drain and fill process. Do not drive until a couple drains and refills have been done.

Yes on the 07 or newer TL you gotta do the rad, but he does not have one.

^never mind you missed it. Flushing the system won't do squat until the op makes the repair as described in post #9. it is The ONLY place for trans fluid to get into the coolant and coolant into the trans on the OP's car.
How many times do I have to tell you that the 04 TL does not have a heat exchanger in the radiator?
DO YOU UNDERSTAND THAT?

OP,
order part 19430-RCA-A51 (#1) in diagram
http://www.acuraoemparts.com/delray/...All&vinsrch=no
easliest way swap fluid is to
drain, fill and drive 10-15 miles.
repeat above 3x

You do not want to attempt to drive the car until you have most of the coolant out of the transmission. I'm usually optimistic but I can't think of a time when a transmission survived coolant contamination but maybe you'll be lucky if you caught it quick enough.
Once you've done at least two drain and refills with it in park, then you can start driving the car between refills.

not sure if this is a good method but it does switch all the fluid....
I have never tried the method either but here it is:

I didn't see the video but it looks like the cooler like method. I usually do it that way depending on how long it's been since the last change. That's a very good idea in his case.
