Automatic Transmission Cooler Lines

Pressure out the pump is NOT like the PSI inside the transmission. It is only like 45 PSI out the pump back through the return.

I am doing mine now. New Cooler mounted up front and new steel 3/8" lines . I stopped the hard line on the frame rail and am using Steel Braided PTFE hose with 6an fittings to go from the rail to the fittings on the transmission for easy access should it ever need to come out and be serviced.
