Default "Power" light blinking, strange buzzing sounds (92 Legacy)

I have a 1992 Legacy, and when I turn the car on (not ignition), I hear a strange buzzing type sound coming from inside the transmission pan. Drained fluid, took pan off and can't seem to find where it is coming from. Sounds like a relay going on and off. But as it buzzes, the green "power" light will flash the same pattern as the sound. And the AT fluid temp light will do the same thing. Any ideas?

the AT fliud temp light flashing means you have an electrical problem in the trans. a trans shop can read the code and tell you. there may be a way to read it your self but i'm not sure how.

it is probably a solenoid, maybe a shift solenoid. (solenoids control the flow and fluid pressure to get the trans to do what the computer says.) there are several in the trans. the "valve body" inside the pan on the bottom of the trans holds a bunch of them. you can probably replace the bad one if you can identify it. if you have to pay for it to be done, it may be very expensive.

it may be possible to replace the whole valve body from a good trans or depending on the repair cost, just swap in another trans.

Thanks, I will keep looking into it.
I am going to try a few more things, such as check the ground for the transmission ECU. I also read somewhere to look at the ATF temp sensor, but I am having trouble Identifying that.

ATF temp sensor is bad, I believe. If anyone has knowledge of what it looks like/how to replace, please share!

I'd check what the TCU is telling you the problem is.

You can pull the codes from the TCU. The instructions are on my site.
