Did you look at all the fuses? Like pull up the manual and decode which ones might apply to the TCM/ECM? Most valve body and well pretty much all TCM codes are generated while vehicle is in motion as it looks at the input and output speed sensor ratios and to see if the gear selected is providing the correct ratios. If not it points the finger at the valves responsible for those gear selections. But if not moving, no codes so you have have to test things. My concern is that you have an internal leak like this article talks about.

Now do a search like "A960 pdf" troubleshooting repair and simply start reading...
There is a ton of info on this trans.

All fuses are fine, I read the technical bulletin link and I get it. The SR exhaust port might be allowing by-pass fluid to escape which is not providing enough pressure to the solenoids,,, but let me ask you this. I start the car, shift to Drive and it does nothing. I then click over to manual and it immediately shows gear 4 on the digital display on the dashboard. I then manually shift to all gears via the display but the car does nothing. Do you know what solenoids control 1, 2, 3 gears and reverse? I'm thinking of replacing solenoids before I have to drop the transmission...

As much as I'd like to help, you have two options; diagnose and replace peice by peice or replace.
To do the first you need tools to pull the VB, an ohm meter, a power supply, and pressure gauges as well as a compressor. Not to mention a subscription to TIS. Www.alldatadiy.com won't do it....

I bet you are still low on ATF. Or your TC is bad since u had burnt fluid. I took my trans out once. replaced a seal put it back in and it still leaked. Took it out again after some research i found the torque converter was bad so I ordered a new used transmission. I drain all the oil and replaced the filter and I put in 7 1/2 quarts, almost two in the torque converter. That's what I had on hand and I put the transmission in the car got another Court and put that in. So now I'm at eight and a half quarts close to what full capacity is. after starting the car it moved but seemed like it would slip and move real slow. I was only about a half a quart low and that made a huge difference after I put in another half a quart. I didn't have access to ATF WS so I went with Valvoline maxlife and I decided to switch it out to ATF WS but was not going to take out the transmission again so I did about 8 drains and refills of about a quart and a half to 2 quarts every time. I ended up using 8 quarts of ATF WS in the car definitely seems to shift better and run better. I definitely recommend making sure you get ATF WS and get the fluid levels correct
