The PML pan is all you need. Your Titan already has two transmission coolers installed.

I've read that i`ve got two transmission coolers..if this is right.#1 is internal and #2 is external between the a/c condenser and rad...people say the one inbewtween the a/c and rad is not placed very well and doesn't get much air flow and doesn't cool very well.....i`m guessing thats why people are adding the extra cooler...i`ve seen pic`s and write up`s on people adding the extra trans cooler in front of the rad next to the rad fan for better air flow....just wondering if i can fit a cooler with fan there...

Ask to see the engineering degrees of the people giving you the advice. Or: Nissan had engineers decide on transmission cooling.

Thanks for the link 04titanss...very useful and I think I'll stick to the external cooler without fan...any idea how much extra ATF it takes if you don't bypass and keep all the coolers plus your new 1?....

The same group of engineers that decided on intake air management, exhaust management, ignition timing, valvetrain etc etc?

The trans coolers supplied are enough to cut it for light to medium towing, not long term heavy towing. Why not protect the transmission with the additional cooling? It's not like the trans can be too cold, and we know what too hot does to it.

The transmission fluid can be too cold. That is why there is a thermostat in the air cooler that bypasses it until the fluid gets up to operating temp. The transmission won't shift into overdrive until the fluid is up to a minimum heat.

If you're towing you shouldn't be in OD anyway. Having said that, it's not like the trans will be in OD lockout full time no matter how big the additional cooler is.

Thanks for posting the info again for installing an additional cooler. This seems to be just the thing for towing long distances in the summer heat.
