I have a new replacement radiator for my 1987 F150 but the replacement radiator is for a F150 with automatic transmission, my F150 is a 4 speed stick. Do I need to cap or fill the auto transmission chamber in the replacement radiator so it doesn’t warp or leak?

You don’t need to cap it but I would, then if you ever get a leak between the transmission cooler and the radiator you will never even know it.
