200-4R TC Lockup Kit - build your own

[V8 Rumble]

I've seen those kits they are very pricey. The Ron Francis kit is similar to yours but doesn't use vacuum for the 4th lock up.

I'll more than likely follow what your doing. Gotta save the cash.

I updated the hardware post with new found part numbers. Vac switch is GM 212331 or 14032087. Matching pigtail is PT293.

Nice work

I could probably grab a factory set up from the wrecker here. My 81 Delta 88 had vacuum lock up for the TH250C, but I didn't realize it and left it on when scrapped it. I used the TCI lock up kit which has a sensitive adjustable vacuum switch. Locked/unlocked like mad until I adjusted it on my 70. I may have went too far, sometimes it wouldn't lock. It works better on the 88 with the stock peanut cam Olds 260. A big cam and low vacuum might not play nice with a vacuum switch set up.
