Transmission was replaced.but now new problems ('98 Accord LX Automatic 4 Speed 2.3)?

These transmissions are god awful. Honda… Reliable? Lol. Those two words shouldn't ever be near each other unless the word "isn't" is in the middle.

Got the '98 accord 4 cylinder transmission replaced and now the car when coming to a complete stop it's a huge delay and you hear two thumps coming from underneath. Can it be the sensor? Did the noob mechanic forgot to switch the transmission sensors on my old transmission to the other? Noob move. Because it is impossible for a transmission to be defective already. And when I gear the car into "D" you still hear a bump

My dad told me I can't drive the car because the transmission will be ruined. What do you guys think? I need to go to work tomorrow…

Added (1). Okay so the car is going 20-30 mph and you come to a complete stop. You then hear "two thumps" after about 2 seconds… And it sounds like it is coming from underneath

You've had all kinds of trouble with this car haven't you?

When you say noob mechanic I take it you didn't have the work done by a qualified shop thus implying that you have no warranty? Was this a new or factory rebuilt transmission or something your noob mechanic found in a wrecking yard? Which is what I'm thinking as you seem to have concerns as to switching sensors from your old transmission, Whatever that's suppose to mean, Generally if I were to have to swap out sensors within a transmission I'm going to be on the phone with my vendor to chew someone out for sending me the wrong transmission.
