Does slowing down up a steep hill keep engine temp...

No disagreement, some folks need to downshift on hills to keep temps down. This, however is due to a cooling system that is not functioning correctly or was designed undersized to begin with. Do not think it is normal operation, or a part of driving skill. it is a work around for a deeper underlying condition.
Class 8 trucks that routinely gross 80,000 lbs do not have this condition. More and more class 8s are equipped with auto transmissions and routinely operate in the 12 to 1400 rpm range for max torque.

Would you reccomend the purchase of a transmission cooler.

i do not know that I would recommend it, but a couple of thoughts come to mind.
If you have a trans cooler that is in the radiator an external cooler would do 2 things.

1 Prevent it from leaking antifreeze into the trans if it fails.
2 It would remove some heat from the radiator, thus letting it keep the engine cooler.
