you can add an inline filter on the cooler inlet side of the tranny cooler hose.

see above link


I use this filter for both tranny and steering fluid filtering. install before the cooler as fluid should be filtered hot not cold.

the 3/8 inch fitting size worked for both my power steering and tranny hoses

this one...

this works for both fluids the website is weird in that they have a seperate listing for steering and tranny fluid filters, yet they are both the same part. I called and asked them for confirmation. So one type works for both fluids, no difference.

double check your hose diameter before ordering, mine is 3/8 inch on a 1990 XJ.

clean fluid rules!

I agree on the filtering hot statement. Hotter will mean lower viscosity and therefore the magnetic filter will have a greater effective range to pull particles out of the fluid.

Adding a filter shouldn't hurt. I wonder if magnets in the filter would be more effective than the magnets in the bottom of the pan.

I wouldn't think so do to the speed of the flow, you sure can't beat a good magnet in the pan.

The Magnafine filter has both a magnet and a pleated paler filter inside. It also has a bypass valve. I have cut one apart to find out.

Hot fluid filtering in addition to better magnetic capture of lartilces as stated is also of
help to reduce back pressure thru the filter media as thin oil flows easier thru the media. Less back pressure means less pressure loss and less bypassing via the bypass valve.

This is why be it tranny, engine, power steering, etc.., oils should be filtered prior to cooling.

I hose clamps the filters in place to the body panel just below the radiator, behind the bumper.


With the price of a tranny rebuild these days, A bit of extra filtering might be $aving money in the long run.
