370z torque converter

How it going I made another post about swapping out transmissions but looking at my other options I been doing some research and came to determine that my problem looks to be the torque converter here’s a little about the problem I been having when I put the car in drive or reverse and don’t gas it stalls when I gas it it starts vibrating a bit a and seems to run perfect after that seems to be changing gears perfectly to me but when I get to stop sign or intersection it shuts off my car only has 42k miles does anyone know if replacing only the torque converter would solve the issue I was planning on getting a high performance one from level 10 what are the chance something else in the inside might be wrong as well? Would guy recommend just doing the transmission rebuild at the same time or would I be ok just swapping converters anyone that’s gone through this before or if anyone has a clue could you please let me know any help or ideas would be appreciated
