This is quite possibly the richest printed statement I've read in over 15 years when one of my sons, a wee lad at the time, posted a note about his sister on the fridge, "Hannah is stoopit and she can't spel!"

I'll try to answer all questions.
I was repairing cars for 20 years and never needed to remove bolt like that. I am pretty sure, nobody sells a tool for it because Jag is probably the only manufacturer using it.
ECM is the last thing thieves want to steal, so there is no need to install security bolt.
I need to remove this connector because TCM is not "talking" to ECM, so I need to check wires before replacing TCM, which same idiots engineers attached to valve body. Dealers don't sell TCM w/o valve body, I don't want to call a dealer about price. If TCM is bad I'll have to buy used transmission.
I called Advance auto and Autozone, they don't have them.
I found one on Walmart website, I could order it and get it in a week or so. that would be a smart way, right?

The engineers weren't worried about thieves, the concern is protecting the integrity of the connections to the ECM. Without that, the car is a very expensive brick, so they took pains to make sure that only somebody with the proper tools and knowledge would risk disconnecting it.
The good news is that security bits are now readily available so that part of the equation is taken care of. The other good news is that ECM and TCM are hardly ever the problem. It's so rare that you should assume it's something else. Checking the wiring and connectors is a good start, make sure all of your earth/ground connections are clean, and look out for corrosion hindering the signals. Just take your time and be careful.

I was going to suggest the possibility of Jag using such a fastener as part of 'idiot proofing' by the OEM but such efforts have always just dissuaded average and below average idiots.
Back in my engine OEM working career, it was blatantly obvious in reviewing component removal statistics from the field and without looking at actual confirmed failure rates, which widgets were the easiest to remove. The ones with the fewest, easiest to remove fasteners always got blamed for engine problems.
The awkward hard to get at part was almost never removed, despite the troubleshooting instructions that clearly made it #1 suspect.

It seems like problem is gone, no transmission codes. I need to check/add transmission fluid and drive it.
So, who is the best Jaguar mechanic in the world?
This is second car with CAN problem which I bought dirt cheap. First one was Jeep Grand Cherokee, where door window switch messed up whole CAN system.
