Re: th350 Transmission Vacuum line to intake???
Same size as the modulator on the trani. I would not go smaller ID size. I have used different size ID hose and had no changes as long as ya get it sealed up with no vacuum leaks!
I like to bend solid line and use a short hose at each connection. Vacuum can suck a line closed causing fast shifts & other problems.......Just my 2 cents worth.
