Another 700r4 question? TC lockup... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ok here's my situation. I need a TC lock up kit for my 700r4. My bro-n-law built the tranny and he recommends going with a factory style set up that has a vacume switch "and" a brake switch to unlock the convertor.

So far I have found that Bowtie Overdrives kit is brake unlock only. Painless wiring sells a kit, but it includes the internal solenoid, pan gasket, etc for the internal mods that I don't need and it's 129.00

The only other one I have found is from TCI. I think it has everything I need, but it's like $80.00 from Summit.

Can anyone recommend any other options that will allow both brake "and" vacume unlock....
