I have rebuilt the transmission and the turbine for my 59 Dodge.
Now I want to put a magnetic filter on the return line from the oil cooler.
But what line is returned, the upper or lower?
You wise guys out there please inform a beginner in the Forward Look.

My tech book shows the lower as lube pressure (out) . So upper is return.

What do you mean by a 'turbine' ? Also, what is a 'magnetic filter' ?

Attention, the Tech books are not always correct - you could unscrew the hypothetical return and add a fitting with a short tube on the trans - a see through tube connected between will show you immedeately at startup if this is the return.

What you may want to consider is a magnetic washer on the sump of the oil pan. That way it's hidden, just have to install it in the best area for catching debris. I know GM uses these today, they can be purchased at dealerships.

Hi Ron, he means torque converter - many times referred to as a "turbine" here in Sweden.

The magnetic filters are a good idea, although the filtering of the trans fluid is the most important. The filter will catch clutch residue and also other harmful particles, while the magnet is supposed to pick up cast iron and iron particles.

Normally, those filters should be installed on the return line, just after the oil cooler.

I have one mounted since many years, in fact, perhaps it's time for to change it now.

I would rather want metallics to be kept inside the pan than going through the cooler lines. Put a magnet in the oilpan near a drainplug or a corner of the pan out of the way from the filter.
As for an inline magnetic filter, I don't want metallic clogging up and hindering flow through just that important part of the transmission.

I'd have to disagree, you want the filter before the cooler to prevent debris from entering and clogging the cooler.

Well, if you run a standard oem cooler, that's just a piece of pipe that won't be clogged at all - even a modern oil cooler is practically a piece of pipe. The reason for to mount it on the oulet of the cooler is that hypothetically, particles might be collected in the bends of the pipe, fall down in case of a total oil change and then damage the trans - hypothetically

I think you'll find that even the OEM cooler is more than "a piece of pipe" and take a clue from the factory, they installed the external filter in the pressure line.

Nope, at least in the '60 Chryslers its really a piece of pipe in the bottom of the radiator - I was there when a Company opened up the radiator for to re-core it. I must say that I wa dissapointed - I thought that it was more of a technical soution

They are in the bottom of the tank because that is the coolest spot, and yes, it's only a length of tube with the fittings that pass through the lower tank. At least that's what was in the last one I junked out. Don't know what it was originally from though.

The coolers that I've cut apart were double-wall thin brass, the inner wall is corrugated to expose more area to the coolant.

In either case, the cooler is a place for debris to collect, just like inside the trans itself...putting the filter upstream of the cooler keeps junk out of the cooler and the majority of the lines.

OK, so what's between the inner wall and the outer wall? Antifreeze or tranny oil?

Almost sounds like 57 is describing the "cylinder" thats the thing inside the radiator as a tranny cooler. I can't picture how a double walled external cooler would work.

All an external cooler is, is a smooth bore tube surrounded by fins. The fins get clogged by crap, dust, dirt, oil etc. if that's what he's talking about. The tranny oil has no contact w/the fins. They are there to dissipate the heat is all by being in contact w/the outside air temp. Same as in a radiator, they "radiate" the heat. I've seen external filter cans before mounted in line. I think they are even listed in some of the 50's & 60's parts books.

The tranny cooler in the bottom of the radiator is only going to bring the temp down as far as the antifreeze that is en route back to the water pump.

Trans fluid.

Picture two tubes (thin-wall brass), one smaller in diameter......the smaller diameter tube is inside the larger diameter tube and they are joined at the ends (double-wall), the fluid flows between the inner and outer wall so both the inside and outside of the completed tube are exposed to coolant. The inner tube is often corrugated or there are swirl baffles between the two walls to increase the surface area that's exposed to coolant.

When the whole thing is assembled it does appear to be just a piece of tubing with pipe fittings on each end.

I did this last summer, I put mine inline before the trans cooler. Keeps the cooler from getting debris or gummed up. I'll post a pic of the setup I used.

So, how does the alleged debris get past the screen in the tranny?

The internal screen won't stop the powdery residue from worn clutches/bands.

Even with the internal Dacron filter you'll find lots of that residue downstream of the filter, this stuff is so fine it will cake up in any available nook/cranny. Anybody who has overhauled a trans will be familiar with it, most of the time on an overhaul is cleaning out this stuff.

Indeed. Filters can only block particles upto a certain micronsize. Anything smaller than that still gets through the filter.

Here's a pic of the filter I used, also the filter and cooler location. I mounted the filter up front next to the cooler.
