    Transmission lines and magnefine filter

    2008 EXL

    At long last I'm going to install this magnefine filter on the tranny line.

    There is one line from the driver side of the radiator another one from the center of the radiator, both going to the transmission, I'd like to install it on the return side after the cooler. So to avoid hassle of disconnecting and squirting ATF all over me, does anyone know which line on the 08 is the return?

    Perhaps post #9 in this thread will help you:

    It indicates that the transmission fluid return on a 2005 is from the driver's side hose. (Other model years may be different.)

    The shorter piece coming out of radiator, somewhere in the middle, is a return line.

    To figure this out, I disconnected the rubber hose, and attached another longer hose to the radiator and the empty 1 gallon can, started the engine for 10 seconds, watched ATF pumping out into my empty jug. Didn't spill a drop.

    The 07+ is different than the 05-06 and the 06's return line is the pass side one. I believe the 07+'s return line is on the driver's side.

    Yeah, I was vacillating between the two for a while as I was copy/pasting to my notes from previous posts and it did seem to change sides at some point but I couldn't figure out what year exactly.
    Was leaning toward the shorter/driver side as the return, I will still disconnect and connect two clear hoses into a gallon container and see which way it flows just to be 100% sure. I'll post afterwards for the beneftit of the other op's.

    Also slightly off topic the 2008 tranny is fairly reliable right? I seem to remember reading a thread back along where one of the op's had attached temp sensors on the tranny lines both into the tranny and out from and temps where well within safe range even in mountain type driving, anyone else recall reading or can confirm safe temps from an 08?
    I dont want to install a cooler if it's just not necessary.
    That op however did get very high temps from his power steering lines FYI concerning ones.

    Yes, the '07+ is significantly improved and I want to say that was OdyFamily that monitored his fluid temps under multiple scenarios coming to the conclusion that even lightly loaded traveling uphill the temps exceeded what would normally be ideal. Pretty sure that was on an '04 model, so the previous trans model. IMO, as long as you are not towing or loaded to max capacity on a regular basis a trans cooler isn't necessary. I see you are using Amsoil trans fluid so with the full synthetic fluid I think you are setting yourself up for much better than average chances of 250K+ on that trans. I just cracked 200K on my '07 that has had MaxLife in it since 115K and it shifts great.

    2001, installed magnefine filter, last year. Strange. When van was in for servicing, Mechanic pointed out inline tranny filter. Never knew there
    was one there. On 4th transmission. So not sure if Dealer (first rebuild), or AMCO (2nd rebuild), or independent Mechanic (3rd rebuild). Installed the filter.

    Anyways, after reading many posts, on this site site. Replaced old tranny filter, with Magnefine. But appears the filter is installed before it goes into the radiator cooler. No problems so far. I guess it boils down to, does the filter work better hot, or a little cooler after leaving
    the radiator/cooler.

    Pkface and others thanks for all your input.

    I seem to remember the reasoning behind the placement of the Magnefine before or after the tranny cooler was not for temperature considerations, but for the fact that the cooler will retain debris after use, so it is recommended before if a new trans cooler is in place or after if using existing cooler.

    In the end I don't see the placement of the Magnefine filter making that much difference. It will filter whatever comes through until it is full and simply bypasses. Yes, having it before a brand new exterior cooler would keep that debris from entering the new cooler, for a time, but I don't know how anyone can possibly know how frequently it would need to be changed to keep up because obviously that depends on what kind of wear is going on internally.

    Yep, I think you may be correct. I vaguely remember that too, after you refreshed my memory. I think, one long time poster mentioned he placed his magnefine filter before the cooler, cause it was easier to access.

    Ok on my 2008 EXL

    I can confirn that when lying on ones back under the vehicle the return transmission line comes from the lower center of the radiator ie the flow returns from the center of radiator back to the transmission .
    Sorry the pic isn't the best it's late and i'm tired and cant seem to find a better one.

    CORRECTION!

    The return is the line on the left of the radiator (drivers side) the transmission fluid flows from the tranny into the center of the radiator and then out (cooled) from the left.

    (on my 2008 EXL sorry for any confusion, Posted at 1.46am very tired!)
