A bigger pan will only take a bit longer to get just as hot. Then it will take longer to cool down. A bigger pan is not a good way to cool a transmission.
A better aux cooler will be much more effective to cool the trans. Replace the small one that you have now with a cooler from a 2003-2007 6.0L truck. You'll have to adapt the lines to the 1/2" fittings on this cooler.

This one is like 23”x8”. My old one was 12x7.5”.
I know 2 people who told me 1 of the 2 wasn’t enough. But a combo of both pan and cooler did the trick for them. But they’re also doing a lot of freeway towing

Any chance your trans temp gauge is reading right? 230° even after installing a larger cooler don't make sense, unless there is something wrong with the trans/converter or maybe a kink/restriction in one of the trans cooler lines.
If you plan on keeping the 35s I would do 4.30 gears if you plan on using it as a tow mule, and install a low stall TC.

Towing heavy and slow speeds,and up/dn shifts,unlocked TC,will put heat in it. Might need a fan to help out.

The cooler lines run A LOT hotter than the transmission average temperature. A lot of people install the sender in the cooler line and then get scared of the readings. If you are only seeing 230°F in the cooler line your transmission is well within the safe zone.

Is the sending unit in the cooler line? If so, that's the cause of your high temperatures.

Yeah. I could see that. But the trans was seeping oil after it read near 230°F before getting the new cooler. Wonder if I can use that sending unit or not on the test port. But I’m thinking there must be a reason they mounted it there. Who knows how old these ISSpro gauges are though. Maybe they’ve changed the location since?

it does great moving down the road. Came home empty today an hour drive. 20 min of city driving. And the rest was highway speeds. When rolling down the road I don’t see much over 175 empty. Not sure about loaded cause usually I take the side roads when hauling that heavy of loads. Don’t trust the brakes to stop me at 70mph. With 14k
1. Low speed with torque converter clutch not applied. The fluid coupling is just manufacturing heat. Once the torque converter clutch applies and you have air movement over the cooler the temps will drop as you've seen.
2. WAY over GCWR by almost 2 tons.

im just wondering if I can move that to unit over to the pan? I got a deep pan yesterday. Haven’t installed it yet though. It has a location for a temp probe in it or you can plug it.
