‘24 Civic EX Shaking @50MPH

My car was shaking like crazy on my way to work today (Jan. 27) especially going past 50 mph. I had gotten my transmission fluid drained and replaced this past Saturday (Jan. 24). I’m not sure if that has to do with the shaking but I asked Google and got this:

Key Potential Factors:

•	Transmission Issues 

An underfilled or overfilled transmission often causes shuddering or shaking at higher speeds (around 50 mph).

•	Weather-Related impact: If the storm involved snow or sleet, ice buildup on the rims can cause severe wheel imbalance, leading to intense shaking at speeds above 50 mph.

•	Other Factors: The shaking could also be unrelated to the transmission, such as a damaged driveshaft or a suspension issue that appeared coincidentally.

On Saturday (Jan. 24) when I drove the car after the fluid change it felt good like the car was sturdy like it felt stronger and I was able to go high speed no problem. Could that new fluid have been the wrong one and it thickened these past few days or something idk. Or do you think I just have snow / ice in the tires and rims? My car was buried so it’s also a possibility. I probably have snow in the tires or wheel barriers. What do you think? (Thank you in advance)
