@nipper, sorry for the delay, it's a 2001 4cyl outback with 180,000 miles. We've noticed that the AT Oil temp is very intermittent. As an example it came on 12/16, had the multi-blink flash when the key was turned on for a day and then no multi-blink or light on for several days.
I plan to perform the 3x fluid change over the holiday, although I have my doubts it will fix my problem, I never seem to benefit from the easy fixes but still have hope.
I've been looking for some guidance online, but haven't really found too much yet on the actual repair. One video but it showed the solenoid after it was dis-assembled. Thanks to everyone so far for the help. Will provide update after the fluid swap.
