Any codes in the computer?A hard shift usually means there is too much pressure. We need to check for codes and also perform a transmission pressure test.

The 300 is fluid temp sensor related. Are you sure about the second set of numbers?

16502 comes up as coolant temp sensor signal too high. Just making sure.

Both from the TCM?
