200-4R lock-up control

[dontlifttoshift]

Don't use that TCI switch, we had a bunch of problems with those not actually switching when they are supposed to. There is a factory GM part number floating somewhere on the intrawebs that works quite well. I'll dig and see if I can find a part number for you.....14014519 for the vacuum switch.
