I thought I saw a thread on here where someone else had a similar problem and it turned out to be a very corroded connector going into the tranny. I'm guessing if you've done something as extensive as a valve body swap you've unplugged and checked all connections but thought I'd throw it out there.

Makes sense. A thousand thank you's. I Check it this weekend

FYI, you'll need a bi directional tool to reset the transmission; removing power won't accomplish that on your 2011. Toyota Techstream or some 3rd party scanner with enhanced capabilities. Lower end ones generally won't address adaptive transmission data.

Awesome info. I will look for a scanner to buy.
Thank you

Still working on this. Van had codes cleared with a bi-directional scanner, But I the transmission could not be reset because the sticker with the codes are gone.
I will post the fix when it is done

Thank you for your reply. I wish you where in Hawaii.
Starting to get a feeling, transmission will need to be replaced.
I did check for corroded wires. None found

There are times in Jan and Feb where I too wish I were in Hawaii.......

Don't know if you've had it off, but the transmission control module is mounted to the transmission housing. On the 4 cylinder model its on the front side; not familiar with the six. It a multi pin connector, looks somewhat fragile so use some care if/when you pull it to check for moisture/corrosion. I was nervous when reattaching mine.

Good luck.

I have the V-6 and I did remove the control module connector, I was clean.
Thanks again

I ordered a XTOOL D7 Automotive Diagnostic Tool 2023 Version Bi-Directional Scanner. Cleared my transmission codes, and reset the transmission, and BINGO!!!! It works again! Thank God!
Thanks everyone.

Its to early for me to give advice on this new scanner but this guy on you tube is what made me buy it.
