TH350 to LS 6.0. where does the kick down cable and vacuum hook to? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

suburban99 · 03-19-2017, 03:25 PM

Swapping a LS 6.0 into my 72 K10. Is there a bracket for hooking the TH350 kick down cable up to the throttle? Where should I hook the vacuum for Tranny to? (drive by cable motor). Thanks

I had a th400, so I can only answer the vacuum question, but I used the brake booster line off the back of the intake for vacuum. Works just fine.

could you explain that please? I have a th350 and will doing the same thing. Did you take the hose from the brake booster, connect to it somehow, or is there another hose you are referring to?

My truck doesn't have power brakes, so I used the line on the back of the intake manifold, (approximately 1/2inch in diameter) that attached to the hose running to the original brake booster on the donor truck. I attached a fitting to the rubber hose with hose clamps to get the hose size down to 1/4 inch. Then I used regular vacuum line to to run to the transmission.

Hopefully this helps, if not, feel free to ask again for more clarification

The kickdown cable....Your probably going to have to connect it to the throttle cable somewhere

What did you end up doing to hook up that kick down cable?

I ran the vaccum hose from the ls1 intake to my brake booster. My hose still had the same connection on the brake booster end that popped right into the booster. I have a trailblazer ss/07+intake here that has the same hose on it as well. The 99-06 truck vacuum hose should also work this same way.
Maybe you could T into this one for the trans

You took the hose from top middle of manifold and ran to brake booster?

Jstock85 · 05-16-2017, 01:00 PM

Punished, you figure out what you going to do to connect the kick down cable?

PunishedC10 · 05-16-2017, 09:29 PM
