If I changed the F sensor and the other 5 sensors in the transmission and it still doesn’t pick up speed or shift and the motor light and AT lights come back on and when I reset them the car gains power what am I missing.

What is your question?

When you drive you can not hear or feel the car go into gear and it sounds heavy and the same “F” sensor codes comes out again when tested

What makes this problem better or worse?

Pressing on the gasmm
