Answer 1

if you have replaced the fluid, most likely pressure solenoid valve 'A' is bad.

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
