Before my car gets to 20mph it struggles sounds like a race car but if I let go of the gas pedal the next gear kicks in and runs fine. What is wrong

There could be a clog in the fuel system, doubtful as AI believe it is an intank filter. Or the fuel pump is going bad. Have the fuel pressure checked. It could also possibly need a new Throttle Position Sensor.
