Answer 1

the problem is inside the valve body of the transmission, if you have not replaced your transmission fluid in the last 30k miles you should start there or take it to a transmission specialist

Possible causes

- Dirty transmission fluid

- Low transmission fluid level

- Faulty line pressure solenoid valve 'A'

- Line pressure solenoid valve 'A' harness is open or shorted

- Line pressure solenoid valve 'A' circuit poor electrical connection
