my car shifts smoothly when driving normally but when jerks when i floor it

What is your question?

my car shifts smoothly when i drive normally but when i completely floor it, it does a tiny jerk right as i floor it like not when i’m switching gears, but like right as i floor it (hard to explain) i feel like it’s nomal because i’m putting so much stress on it, it’s very small jerk but i feel like it’s just doing it’s job
