there is also a small griding/winding sound but it stays constant when going into different gears gears

Who did the engine replacement and was it replaced with an identical unit?
One of the first things to do is confirm the level of the transmission fluid https://lemon-manuals.la/Chrysler/2013/300 C%2C 3.6L Eng VIN G%2C RWD%2C Trans Mfr CD 8HP45%2C Gas/Repair and Diagnosis/Transmission/Transmission Control Systems/8HP45 Automatic Transmission (Service Information)/Fluid And Filter/Standard Procedure/Standard Procedure - Check Oil Level/

So basically, there’s a high probability that transmission is toast. It’s weird that it happened right after a shop did an engine replacement job, which is why I think it’s worth asking that shop to take a look at it with a “wtf mate” (maybe phrased a little more politely than that lol) but the diag tests call for a professional scan tool. The repair procedure for a lot of those codes is “replace transmission.” https://lemon-manuals.la/Chrysler/2013/300 C%2C 3.6L Eng VIN G%2C RWD%2C Trans Mfr CD 8HP45%2C Gas/Repair and Diagnosis/Transmission/Automatic Trans/8HP45 - DTCS P1D94 To U1479/Diagnosis And Testing/P1D95-TCM Clutch Failure Undetermined/Diagnostic Test/
At a minimum though, check the fluid level
