Transmission - reverse shift makes thud noise at cold temp

[NewLCGuy]

2017 LC 65k - makes a clunk or thud noise when shifted into reverse for first time, as soon as engine is started without waiting for it to warm up, especially when it is real cold outside. Is that normal ? It does not make the same noise when the engine is warm. I had recently changed the transmission fluid at a dealer. However, I started noticing this sound since last month. I will upload the video of shifting when engine has warmed up. Will upload a similar one when shifted without warming up the engine.

Edit- not able to upload the video from phone.

My first thought is not transmission, but driveshaft. How long has it been since the propeller shafts u-joints were greased?

I got those lubricated last year in May at a dealer. It seems from different forums it is normal to hear a thud sound at higher rpm which the engine is at normally during cold start.
