Would this work or is it too high flow?

I am trying to convince wife to let me take PTU off to clean it and drill drain plug. If I do that I think one of the pumps above and an oil cooler would be a great add for my non pp sho
Make sure there is a filter in there, I am sure heat contributes to the sludge, but you need to keep clean oil going thru a cooler or it will just clog. plus is you are already plumbing, might as well go for it.?
I saw those pumps as well and that small one probably would fit the bill well I believe, just seems a bit expensive for a gear pump?
Hopefully some of the PTU/transmission pro's may be able to shed more light, but to me in a perfect system it would go: PTU->filter->pump->cooler->ptu.
Pump pulls oil from the ptu, thru the oil filter so the pump and cooler are protected from the sludge.
Here are some of the "hurdles" I see with developing a kit/setup for this.
- What sort of pressure is there in the PTU normally?
- Can the seals in PTU handle the possible extra pressure of a supplemental cooling system?
- How well will that pump in the link above pull oil, some pumps are good at pushing, some pulling? Ii is designed as a scavenge and I believe gear pumps typically are good at pulling oil.
- Can the pump handle the heavier 75-140 oil used in the ptu?
- Can filters to handle the gear oil also handle being under vacuum with the pump pulling heavy thru them?
- For pressure concerns I could see the filter and pump be swapped, as that would probably limit the pressure going into the PTU because the filters will be the flow limiter and create back pressure to the pump. But subjects the pump to heavier wear. Of course with a filter running at all it should be limiting the overall grit in the oil anyway... PTU->pump->filter->cooler->ptu
- Is there a factor/setting in the ECU for temp? Would being to cold cause DTC's or other harmfull side effects
Thoughts from the experts?
Here are some other options I saw, might be worth trying one even just short term for a proof of concept before dropping the coin on the top line pump designed for high temp turbo oil.
