You need a controller to provide 12volts to the 200c in order for the lockup to engage. I haven’t looked back in this post but I think we discussed the B&M adjustable lock up controller that integrates with your stop light switch, or you can just use a manual switch to provide power.
I believe the 200r4 is the same, someone can confirm.
The 200c is a manual shift linkage. There may be computer controlled 200r4 but the ones I have used are a manual shift linkage and they re plentiful.
I’d find another trans guy.
