    i'm gonna be moving this summer, and that move will cost me 2,000 miles on my truck, so i'd like to do some maintenance and preventative measures.

    I'll probably be towing a small single axle trailer (originally built for a pair of jet skis) with 2 400 lb quads on it, and my bed full of stuff.

    I'm planning on rebuilding my leafs, getting new (rear) shocks, adding a AUX trans cooler, and hopefully figure out how to get my trans temp on my phone (via torque).

    I was talking to Dad about the trans cooler last night and he said to just take the factory cooler (in the bottom of the radiator) out of the picture and run a bigger cooler in front of the radiator, my question, will this get to cool?
    i know they make thermal bypass's for this, but would bypassing the cooler completely cause the temp to skyrocket, causing transmission damage?

    the thermal bypasses will only bypass the cooler till the fluid temp reaches a preset lvl then it will flow through the cooler circuit

    Yeah, i just don't want it to heat up to fast, if thats possible.

    Also, i've read a lot about people adding inline filters, I assume this would be a good idea, any recommendations for a filter?

    and where would i want to add a sensor for trans fluid temp? as close as possible to the trans on the hot fluid coming from the trans?

    You can bypass. Early 4Runners are experiencing strawberry milkshake when coolant and ATF are mixing together. I beleave it's caused by neglect with the cooling system. Make sure you get a stacked plate cooler and install it as close as you can to the condenser. I run the TRD (Hayden) in series with the radiator cooler. I towed 4000 lbs 1500 miles and my temps were between 170 and 220. I have a Autometer trans temp gauge. Run synthetic aft and you shouldn't have any issues.

    Magnafine makes a inline filter. I ordered mine directly from them. I used a block manifold from summit racing that attaches two hose fittings and the sending unit. I have mine coming out of the transmission. The filter can be attached in any rubber line. You want readings coming out of the trans since it's the hottest temp.

    I have been debating this same question. One answer might be... How much space is available?

    Well, if i put it in front of the radiator then you could fit the largest one they offer i believe.

    But then you could overcool it.

    I think i'll get the 14,000 GVW one and if it ever runs above 190* i can add a smaller cooler on a thermal bypass.

    Yeah, I only have the driver side of the radiator available. Even then, space is restricted on that side because of the A/C lines.

    Not to mention you HAVE to have thos coolers with the hose connections facing up or with one up and one down. So you need to think about where hoses are going to run.

    well that limits you
    Me to?
    Sounds like a plan, I don't think i've seen a fan that would work on that though.
