TH350 vac line needed?
so my question today is, do you need the vacuum line for the th350 that runs to your intake? my friend said you don't need it and iv never heard of this before, its currently off right now but im not driving it as the truck is still being assembled so id like to know if this is a do or a don't before I drive it, I don't want to wreck my trans
also the trans has a stage 2 shift kit and a 2800-3000 stall converter installed |

Re: TH350 vac line needed?
If you don't run the line the trans will shift very late and hard.
The vacuum modulator controls the pressure. Zero vacuum means max pressure. The trans doesn't mind but it will drive like crap.
