Re: '50 Ultramatic Trans Cooler Lines

Good point, the in-line cooler would probably provide better cooling when still than a small accessory cooler. Remember than whenever the torque converter is being used, all of the inefficiency is just heat dumped straight into the transmission. This is particularly relevant in driving with lots of long stops, or lots of hills taken at a moderate speed, where the converter is needed for torque multiplication.

I don't think I've heard much from Ross regarding external coolers, but I heard he likes to paint the converter housings black to increase radiative heat transfer.

As for what order to run an external cooler, obviously having the air cooler after the water cooler would drop the temps more, but I doubt it matters much in practice. Already with the water cooler, the temperature is outgoing radiator temperature, which is still cold when the engine is cold, and probably not too warm even at operating temps.
