Building oil coolers is a messy business and they are very diffcult to get clean. So the one thing you wouldn't want to do would be to have cars coming back for engines because another one of your coolers gave up a chunk of this or that. And in any case once you blow an engine there will be crap in the cooler and now you have to have a filter after the cooler, or loose another engine. Cooled and filtered would be the minimum. So any oil source that had been cooled and filtered by at least an "Inline" filter would work fine. I don't know if a metering feature is involved, to limit the oil flow to the gear box, but a course filter with a magnet would be in order. Lynn E.

Are you cooling the oil before filtering or are you filtering the oil before cooling? If one was to stick to the original design and utilize the original oil pressure outlet as the oil supply feed to the re-drive, it would appear that this oil supply to the re-drive is un-filtered oil although the oil is cooled.
