Got a 07 V6 4x4.. Did the bypass so it only has that small cooler.
Take my jetskis to the lake this summer. Lake is about 70 miles away and going to launch them from the beach.

Best to get another transcooler?

not for a load that light, the thing wont break a sweat... I've had 3000 lbs behind mine and forgotten its back there.

So is there a load limit where the additional cooler would be needed? I've seen threads with users talking about monitoring the transmission with a thermometer, but not sure there have been any conclusions.

the load limit would be determined by the transmission fluid temperature
you can install a trans fluid temp guage to determine that
be careful with the hardware, materials, and routing
one of our members had the temp sending unit apparatus fail and lost his trans fluid :(

its not a load limit per say, mine answer was an educated opinion. Those jet skis weigh very little in the grand scheme of things, for something that light you shouldn't need one. Installing a temp sender and a gauge would be the only true way to measure it. But again, those are so light, you shouldn't have a problem without it.

Thanks for the info crew!

What about unloading them on the beach in the sand... Would that make a difference?

A dry dock

So what is the temperature then where the additional cooler is needed?

I tow 5000+ lbs and live in AZ so I'm assuming I'm going to need the additional cooling capability.

I think the majority of your heat build up is going to be when you are driving at highway speed and their is higher RPM for extended periods of time. Driving up a launch ramp or on the beach is probably a very short drive and there is not too much heat build up compared to highway driving.

I assume you have 4WD if you're planning to tow in sand?

Are you by-passed as well? I would think it would make more sense to replace the radiator and go back to a stock setup before adding another cooler. The stock setup can handle what you're doing.

No I'm not. Since Nissan extended the warranty I've delayed doing the by-pass. I'm just over 60K miles.

I'm thinking instead of doing a coolant flush I should just replace the radiator when the extended warranty is almost up. I don't think the cost is that much different between coolant flush + new external cooler + bypass vs. new radiator. The only question is do I trust the new rad not to fail.

that's a good question, whether aftermarket or OEM
BTW: the normal operating temp for ATF seems to be in the range of 150-220 degrees (thanks skinny2 :) )
