I have the Superior switch. Doesn’t work. No matter how much vacuum applied, it doesn’t switch to NC to COM. Is this switch the only think out there or is there another option?

I bought a switch that screws into the trans and works off pressure, I haven't done the swap yet so can't say how well it works, Monster Transmissions in Hudson Fl also sells a similar kit

I was not too clear. I would like the same kind of switch (vacuum). Just a different manufacturer. And one you could easily mount to the firewall. Just read an article saying you should hook to ported vacuum. Currently I have it hooked to manifold vacuum.

Have you pulled the hose to see if there is an adjustment screw inside there?

 

[Jim_66SS]

Adjustment screw is in. Appears to not work with internal part of switch stuck in the NC position. But by taking adjustment screw completely out, I was able to stick a probe in the vac hole and get it unstuck.

I have the TCI switch.

Summit has the TCI vacuum switch #TCI-CMP3766B for $30 and it is meant to work with the $150 wiring kit TCI-376600.
I do not have a recommendation on any specific model, but I found plenty of options for lockup switches at Summit here.

I have a $99.00 Electric with an oil press sending switch. For my 700R lockup. Start the car stick it in O.D. it shifts at factory specs. 13 - 36 -- 55 & loc /up. Why this type ??? NOT a dam thing to screw with, Put it in gear and drive it shifts up & down and I do NOTHING. It shifts just like my Silverado, WHY? Its a cruiser, The wife and I go on some long trips in my FAKE 1970 SS 454 Sta. Wgn. NO BUTTONS,,, NO SWITCHES,, NO GADGETS ! How well does this system work? I installed it 14 or 15 years ago and just a little over 65.000 miles on the " SIMPLE SYSTEM ", So I guess its an " OK " set up ! I tell the wife or anyone that drives, Stick it in " D " and go. I just love the " KISS " method !

This is a P.S. Yes you can play with the shift points up and or down. I just want something that would work and have " NO NEED for a flight manual " CHECK LIST " to drive the dam car. Some Outfits have this type of an IDEA for a SIMPLE SHIFT KIT...................... " Lets not make this difficult,,, Lets work at it and make F##KEN Impossible "....................................
