I have my 84' K20 with 700R4 at the trans shop (been there for weeks now) and the owner said my TCC valve/switch just to the left of the vac brake booster has a broken port for the vac hose. I know GM doesn't stock those anymore but it appears that RockA and Napa still do. Where however, does the the other end of this vac line connect? This is now a non smog rig with no TVS(?) to trigger the vac switch when water temp gets to 170 degrees. So where do I want to hook it up?
