Im just finishing up a c6 install on my truck. It has a TCI full manual/reverse pattern valve body. At some point, I lost the instructions/paperwork. I was wondering if I need to run a vacuum line to the trans, or just plug the port? The C6 is replacing an AOD, so there is no line, and I dont want to run one if its not needed.

Thanks,
Chris

I would run one. I have the same set up and i did not run one for a while and then i started running one. It does not seem to make any real difference.

Go to TCI's website. I believe they have all the installation guides available online for you unless they have changed their site.

Of course not. The vacuum is to power the modulator which is no longer needed either. FYI that valve body has no compression braking either.

Now is there one that does ?

I have one and it works great.

ditto on the compression braking. AWESOME! Got mine from Broader Performance.

Ditto on no vaccum, Plug it.
