So if/when you replace the radiator, do you still route the tranny lines through the new one, or still keep the systems separate?

if you are confident in the quality of the new radiator, you can utilize the transmission cooler component inside of it

Thanks for the response. I haven't had any experiences with any radiator brands. Shoot, in 2005 I would have had complete faith in the Nissan OEM radiators. Can anyone suggest a reliable aftermarket radiator for the Pathfinder that they would trust to run the tranny lines back through? Has anyone rerouted their lines back through their new radiator? Thanks in advance!

I haven't heard of any cross-contamination issues with any of the aftermarket radiators nor new Nissan regular and value line radiators. I've had an Ebay made-in-China unit in my 06 for five years and a Koyorad in my 08 for 2 years and have had no issues with them, utilizing the radiator's integral cooler. Most aftermarket radiators are made in China. Spectra Premium has been a very popular choice in the plastic tank radiators. Stillen offers an all-aluminum radiator that is really nice, but is three times the cost.

I believe this is the Stillen one made by CSF. I have a 2011 and it says it's incompatible, but whatever. Unless I'm wrong, I'm pretty sure nothing changed between 2010 to 2011/2012.

Used to have a Spectra Premium I bought from Pep Boys on a 2003 Xterra 4x4. Gave zero issues. SMJ is right in stating that most are made in China. For example, I believe Spectra is a Canadian company, but they source their cores from China.

It should work on the 2011 & 2012 models...but, those model years didn't have problems with radiator cooler failures.

I've got a 2011 with about 90,000 miles on it and I've read that the 2011s didn't have this problem. Is that true or should I just bypass and move on?

From what I understand the change was made sometime in 2010 so you should be ok. I have not seen or hear of anyone with a 2010 yet that had any issues.

I have a 2008 that has smod. I did the bypass and replaced the transmission fluid. At this time I don't know if the transmission is gone at this point. I've flushed the radiator with water about half a dozen times. I haven't gotten much of the milkshake out. The most success I've had getting it out is to take the cap off the reservoir, run the engine, and let it ooze out the top. That's messy and a pain. When i drain the water out of the radiator it comes out as mostly water. Then a little bit of the milkshake will come out. the water never seems to get warm either.

Any suggestions for getting the milkshake out of there?

You need to do multiple ATF replacements... there are nooks and crannies in a transmission where stuff stays.. even a small amount of coolant remaining will destroy the transmission.

Do the so -called poor mans flush several times (draining the trannies pan and then refilling)

Dont use expensive Nissan OEM fluid for this.. castrol multi car import is plenty good.

Here is how (do one of those drive for a day or two.. do again..)

As for the radiator.. just replace it once you know if you saved the transmission

+1 on palmerwmd's post.
the residue in your coolant is the absolute least of your problem.
the coolant contamination wrecks the transmission, even a little bit will do damage.
flush the trans, flush the trans, flush the trans,...............
