Aftermarket tranny cooler?

Back story...
I've got a 2008 V6 2WD R51. I've recently picked up a 3,000lb. camper trailer that I'll be towing. My first orders of business are mirror extensions and a 7-pin wiring harness & brake controller. The camper trailer already has a WDH and friction anti-sway bar, but I'd like to eventually get some airbags to supplement the rear suspension as well.
My question is...
Do I need an aftermarket transmission cooler? They seem to be cheap and easy to install, but I've been getting mixed signals on the forum whether they are worth it. My understanding is that the R51 already has a transmission cooler from the factory and this one may be of higher quality than many after market options.
If I limit the amount of overall shifting the transmission is doing, will this help keep the temps low? Especially when towing uphill. Or do transmission temps tend to follow overall load on the engine?
I've got about 115k on the odometer and I've never serviced the transmission. Is a flush in order? It shifts fine in auto-mode, but has a hard shift from 2nd to 3rd when shifting manually.
Thanks.
