Need pictures of the part but your guess is probably correct.

Hopefully one of the Toyota techs will look at this and know. As you stated, possibly a cap that is suppose to be on a solenoid?

Oh, and Toyotas answer to transmission issues is replacement. From what I have seen and read Toyota dealers do not repair tundra transmissions. They my recommend a flush and then if things get worse they recommend a replacement. If you happen to live where there is import transmission specialist they may replace some solenoids or other parts but Tundra transmissions seem to be a voodoo topic at most transmission shops.

On my 2016 sr5 4x4 At 66,000 my transmission started slipping as i was returning from a trip. I was towing a trailer which was about 10k lbs.
I only tow 2 maybe 3 times a year.

The next day, the check engine light appeared and i took to dealer. Took them acouple days to diagnose the issue due to them clearing the check engine light. They then ran a compression test on the transmission and it was out of spec. Ended up replacing transmission.
The transmission housing was a "reman" but all the guts were brand new.
After replacing they tested new transmission and still had slippage. This 2nd issue was due to a bad shifting solenoid (that was replaced new when they installed trans) so they replaced it with another new one and fixed all issues.

In the end, they were not able to exactly pin point why the transmission failed in the first place.
Truck is lifted on 2.5 oem king shocks, and im running 305/55/20r wheels.
They even checked transmission oil and the oil was still clean. This was the original factory trans oil. At 66k miles i have never flushed or replaced or even touched trans oil.

All covered under extended warranty. Total cost to dealer parts anand labor was about $5,300.

Per toyota master tech, the solenoids are rebuildable and toyota whill recommend doing that before resorting to replacing the transmission.
