monte70car Posted June 2, 2017 Share Posted June 2, 2017 I need some help so summit racing let me down on a part, year one let me down on a part. So here is what I'm looking for, I'm looking for the fittings that goes into the transmission case so the lines can connect to the trans. My aftermarket lines won't screw into the trans as the fitting is the same size as the port. The part number I got from summit was rnb-800-755 which list for fitting a 350 trans but a 76 and later 350. Did GM change the fitting size as I have a 78 400 trans that took the 350 fittings.
