Bought a used tranny w/ vac mod, do I have to hook it up? Really basic question I know but I bought Probuilt in my sig used and it came with the vac mod already installed. The guy included a line and told me where to hook it up at. I've read mostly cons about the vacuum modulator and kinda wondered if I could just leave it undone. My question is whether or not the vac mod becomes a necessary function of the transmission once installed. If not I will just block the port and go without it.

And no this tranny has never been bolted up yet so I can't just take the line off and see. Hopefully will get to work on this project next week.

That transmission must be hooked up to a vacuum line because it has the epc removed. This is very important because it is what is controlling your transmissions line pressure. The break booster hose is where you should T into. If you are running a blower/turbo you must run a vacuum blowoff kit as well. Most people love this setup when done correctly. Hope this was the answer you needed, Vince.

That's what I needed to know. I'll go ahead and hook it up. I wasn't familiar with the nuts and bolts of that modification. Thanks everyone.
