Anyone here use one? Experiences? Where did you mount it?

I have a 2000 2wd Ranger that has a 4r44e transmission with shifting problems. First thing I did was drop the pan, and do a "fluid change". Also replaced the filter. Also did a flush. Used about 10 quarts. No difference. So after some research, I thought that it could be the valve body separator plate gasket. When I pulled the pan again, I found more debris there, even though I'd only put maybe 10 miles on it since the last pan drop. So I want to install a spin-on external filter that filters out much smaller particles than the internal filter.

Anybody have any good, bad, indifferent experiences with this?

 

I would spend the money on the transmission rebuild.

While transmission failure might be blamed on smaller particles, the particles had to come from an already failing part inside the transmission, this is not a "chicken or the egg" thing, so extra filter isn't the answer.
Finding the source of the debris in the current filter is the answer.

And adding a 2nd trans cooler is always a good idea, heat is the biggest trans killer, not expensive, and if you wanted to add a 2nd filter then add it with the 2nd cooler

 

I may wind up having to do that, but that could cost more than the truck is worth, especially if I paid a shop to do it.

I was actually referring to the fine metallic dust-like coating that settles on the bottom of the pan. The stuff that's too fine for the existing internal filter.

Is an extra cooler really a benefit on a truck as small as a Ranger? Plus, I don't plan on doing any towing. I would definitely do this on a tow vehicle.

 

I put 2nd cooler on my cars, if its an automatic it gets a 2nd cooler, just my opinion.

There should be no "fine particles" or any other particles in trans fluid, it would mean something is wrong inside.
Will installing a 2nd filter make trans last longer?
Maybe, but you know something is wrong now, so...........


"More than vehicle is worth" is a not a valid statement except for insurance companies, lol.

If you have a vehicle that doesn't run, bad trans, then maybe it is worth $500 in parts
If you spend $2,000 on a trans, then vehicle may only be "worth" $1,500, as example.
But if you drive that vehicle for another 2 years, $80/month in trans cost, it may still be worth $1,500 so you are ahead.
Running pickup trucks have a base minimum value, they are not like cars, they seem to hold at a set minimum point in all areas

Up to you really, only you know the worth of the vehicle to you, what it's value is on the open market is set by the buyers not the sellers
