Swapping in an overdrive trans? check out this older article I saved. I believe some of the GM parts are no longer available but if you have an old GM vehicle sitting around you may have them already.

I've had that GM lock-up delay valve on my parts list for years, never seen one for sale, or the alternatives. I have one that looks the same from B&M or Painless, not sure how they compare but articles seem to ignore them and reference the GM version (Delco 214-479, Standard DSV-31)

Interesting grounding through the brake lights. The 200-4R's controls vary based on the original application, and I would bet some of them have an internally grounding switch which would require you ignore the brake lights or put in a relay to address that. It's not entirely necessary in my opinion; if you stop, the TC will not let go until it drops out of 4th gear or possibly 3rd (the pressure switch) and that's okay.

Just like Cruise control, often wired through the brake pedal/lights to drop out.

I've never seen cruise wired to ground through the bulbs, but I admit though I rarely have any trouble with it on anything I own, it might be common.
