Transmission problem
1995 GMC Sonoma 6 cyl Two Wheel Drive Automatic 276000 miles

How much pressure is on the feed & return lines that go to the radiator?
Mine are leaking, and need to repair.
Can I use high pressure rubber hose?
Or do I need steel lines?
Do not want to spend a lot of money, because of the high mileage.
Thank You

You will need to use high pressure cooler lines, 5/16", don't use rubber hoses/fuel lines/vacuum hoses etc. They won't hold up. Easily has over 50 psi especially when cold.
