904 doesn’t start in 1st?

I used to have a 87 Chrysler Lebaron, 2.2L turbo auto trans. Occasionally it wouldn't downshift after stopping at a stop sign or red light. I don't remember if it would pull out in 2md or 3rd, but I am sure it wasn't 1st. You could pull the shifter back and manually shift, and it would accelerate and shift normally. I dropped the trans pan and valve body, cleaned everything, and disassembled and cleaned the governor. Reassembled everything and it worked fine
