We got our new issue of 'Trailer Life Magazine" the other day, and there is an article about transmission filters in it. It seems that newer vehicles have much more efficient filters on their transmissions than the older ones did. The filters used in most automatic transmissions, until recently, were pretty course, meant to filter out only large particles. This article states that even the smaller contaminates can significantly reduce the life of a transmission.
One of the filters they recommended was called a "Magnefine" filter and is an in-line filter with a magnet in the inlet. They are available (on Ebay) priced from $9.95 to $18.00. That seems like cheap insurance to me and I plan to install one in my coolant return line on the transmission and the return line on the power steering.
Has anyone had any experience with these? Is there any down side?

I've been using an in line trans filter since my first tranny failure..with
the regular filter as well of course. I don't have the part number but I
believe it fits a Honda .
The only down side is for the economy, I only change the main, in trans
filter, 1/2 as often. And transmission shops just about anywhere I travel,
don't get a chance to make money off of me ...again !
Just do it!

Carl,
During my bouts with crankshaft thrust bearing failures, I learned that one
of the most likely causes of such catastrophes ('tho' NOT mine) is high
hydraulic pressure in the torque converter. The area of the rear side of
the TC is about 2 sq-in less than that of the front side so that 100 psi of
pressure imposes a 200 lb force forward on the crankshaft. Since that's
near the maximum design load, excessive wear is likely.
One of the causes of excessive TC pressure is restriction of the external
cooling circuit since the output of the TC directly feeds that loop and
restriction will lead to dramatic pressure increases. I DO have an
external cooler, a frame-mounted adapter for a PH8A filter. But I've
measured the output from and input to the transmission at the bell housing
and found <10 psi difference. I'd be concerned if the drop was much more
than that. I have to wonder what the pressure drop is across the newer,
more efficient filters? Nothing comes free.

Another place for restriction or leak causing a dead transmision and tow job. To me the OEM setup has worked fine if you change the Dexron with each birthday. Less is more here for me with any additional pumbing and cutting into steel lines. I feel the same way about the fuel system. 1970 455 Olds 442s ran down the 1/4 mile fine with the mechanical pump and made more HP than our low comp GMC MH 455 version. Hmmm.

Okay, Thanks for the info and opinions. I thought about the potential restriction issue and will look into how restrictive these filters are. I suspect the restriction would be minimal until the filter starts to get dirty and it would get progressively worse from there. I may just leave well enough alone, but then again...
Michael, How long have you been running an in line filter? How many miles? Do you notice a significant difference in the fluid or the sediment in the pan when you do change the fluid?

I had the trans done in 1997 and the tranny guy then suggested the Honda in
line filter. Since then I had it checked out about 2004 0r 2005 when I had
the engine apart...there was next to nothing wrong but I had him change the
clutch plates while he was in there. I usually change the pan filter every
2-3 years, depending on mileage and the in line every year. I have about
60-70,000 since 04/05 which ever it was.
Just what I do <g>
