Where would I find a timed vacuum source on an LS3 engine. I need a connection for a vacuum switch for a lockup torque converter for a 2004r tranny. I have a rebuilt 2004r tranny from a previous project that I didnt use. Now I want to use it in my new project. I am also using the Lingenfelter 58x to 24x converter that I also already have. Thanks, Scott!

 

You will find that the lockup kit made by B&M works a lot better than the vacuum controlled type. The B&M kit is speed controlled and adjustable by turning a knod mounted inside the car. I have used both and the speed type is smoother and will stay locked up at part throttle when it needs to. With the vacuum type, every time you come to a SMALL hill, the convertor will unlock, even though it didn't really need to. The speed controlled type is more expensive, but well worth it.

 

Thanks for the suggestion. Still looking for an answer to the initial question. Anybody? Thanks!

 

Anyone?
