Pull the lines off the radiator. let it drain as best as you can and then use pipe plugs to cork the radiator transmission holes. just get a big enough trans cooler for your application. if you do it the way you are talking about then you are either heating the coolant with the transmission fluid or vise versa. The metal lines add to the cooler capacity of your transmission and rubber lines tend to hold the heat in. the fittings are 1 4" pipe into the case and from the factory are 5 16" steel tube with double flare (like brake and fuel lines) on the end. you can get the double flare fittings to fit 3 8" steel lines but with the sizes of passages in. There is a one way check valve and spring (actually it is a check ball but some folks call it a valve) in the stator support pump cover. that check ball spring is for converter drain back but it is also in the oil circuit for the cooler. cooler flow and converter charge oil are very closely related. that check ball spring sometimes gets jammed.

First pull off the coil wire so the truck won't start. unhook a transmission line and have someone turn over the engine. the transmission will start to pump out fluid. now you can tell the direction of flow. the line from the front of the trans is to the cooler. the line at the rear of the trans is return from the cooler. The early c6 case will not allow the "r" servo to fit without machining the case servo bore. only genuine "r" code trannys (meaning the car came stock with the r code engine and c6) will allow the r servo to fit. later c6 cases, i think around 76 or 77 were all machined and could fit the r servo.
