Then, once it warms up it doesn't happen again.
Am I to understand that there are no updates to this transmission? Will I just have to trust the dealer to replicate the problem and attempt to fix it?

It's just the cold weather, you have to let the trans warm up.
get the trans good and hot then come to a stop. Put the car in first gear then drive the car from first to second winding out the rpm to 4500 before shifting to second. If it don't grind then it's just the cold weather.
you can't shift these transmissions cold.
