Don't get me wrong here, i Like this system and would like to us it .......someday.
I have been thinking about your disagreement that the trans is reverse cooled from the pump.Don't get me wrong here, i Like this system and would like to us it .......someday.
back to the decision.
I thing that even if you could run the pump, through the cooler and backward through the converter. There would have to be a few more add-on's like............after drilling a hole in the oil pan for the feed...........You would need a filter. This is dirty oil aka Unfiltered Oil. You would not want this oil being pushed back thru the system and sticking a valve in the valve body.
If you get all the oil in the pan cooled while the eng is at rest/off. the only heat is in the converter. first fire up and it through the cooler and into the pan. Major transmission temp drop.
I like it!! I like it a lot. Price tag don't thrill me much. butt still like it.
Actually that helped a lot.
Looks factory! Well done!Made brackets for this Derale plate/fin cooler for my sons 69 barracuda.

I implemented this on my 904 this week. Lots of planning but I think it works.In the instruction it said something about installing a warning light on the dash or .......something???
If it can be dump back into the pan threw the torque converter it's self........Then that may be the reason for the warning light.
You would not want a pump on both side pushing threw the TQ from opposite direction, at the same time.
I made my flow path with the fact that it could NOT go backwards..........
Does any body have a flow path for the 904/727.......you know the one that shows the path of flow threw each gear?
......
the converter gets no flow when it is in "P"..........and there is a check valve in the converter???? that keep the fluid from draining out of the converter...........Or is that when front seal starts to leak?????????
Just thinking if there is a check valve that keep the oil from draining out of..................Hmm just typing out loud here.
sence i moved i can't find anything......going to see if i can find my Chassis book. Think that were i have seen the oil flow chart.
904 Torqueflite hydraulic surgeryA little but more details please
is this being feed thru a fan cooler and/or is there a aux pump.
Will do, but that will be a while yet. I posted it here for you because I knew we had talked about this months ago.I like the fact the your picking up the fluid from the filter instead of just the lower side of the pan.
You need to let us all know how it turns out and if you like it...................
Will do, but that will be a while yet. I posted it here for you because I knew we had talked about this months ago.
It's all reversible if it does not work out. Just need some pipe plugs.
But I think it will work fine. There are 3 versions of this Tilton pump
Two plastic versions and a metal version. I got the plastic Viton seal version because it had better seals and is a few pounds lighter than the metal version. Although the metal version seems more durable,
It uses inferior bu a rubber seals that are not high temp rated like Viton is.
I was very careful with the check valve selection. McMaster car has all kinds of check valves.The only question mark.........and is only because it hasn't been tested..........is the check valve........
But then again, even if the check valve failed. there wouldn't be enough leakage through the pump to cause any kind a pressure drop to the converter.
The thing i like best about your design is that you don't need extra lines and two cooler.
one fan driven oil cooler is all you need.
Used 3/8 tube, and added a trans cooler thermostat. Not running the 42RH into the stock radiator. Used some nice hard lines I got from a 1999 B350 church bus in the junky. Added -6 AN fittings to the front, and flex lines. Cooler thermostat bracket is homemade. Everything in mockup stage in pix. Finished up the welding work, sand blasted and primed engine compartment yesterday
