i was coming back home last night from a 30 min freeway drive. i take my exit and begin to floor it to have some fun on the 1 mile long off ramp i come up to the lights i begin to brake and down shift and my car would not go into 4th

i kinda freaked and thought maybe the trans was running too hot so i began to just drive around regularly and it did loosen up but i pretty much had to slam it into 4th gear and hit it out of gear.

should i be worried?

should i change my trans fluid?

could it b something more than just it being too hot?
