I have searched and can't get a correct answer. I have a 1991 GMC Sierra C2500 with the 4L80e. The radiator has the transmission and oil cooler built in. I want to add a external transmission cooler. I am adding AN fittings and lines. The output side of the stock radiator for the transmission. What fittings will I need to convert to -6an lines?
