    I've read through most of the threads on here about secondary transmission coolers on the 1st gens (with Auto transmissions).

    I'm trying to figure out a few more things before I order parts and do the install.

    Tips I have gathered
    • Prepare to need MORE hose than provided (approximately 8 feet)
    • Make sure to add more transmission fluid after the install to take into account the increased capacity of the added line and cooler.
    • Get the biggest cooler you can fit/afford.
    • The pink milkshake is not really a concern for us taco owners, mostly T4R's


    My current plan for parts:
    My setup will be Transmission -> Radiator -> External thermal bypass > External cooler > Transmission.


    Transmission Temperature Gauge
    Yes, I know the ScanGauge II "shows" the ATF temperature with the X-Gauge code. It's a decent general view of how the temperature increases and decreases, but it's not accurate.

    I want to have a dedicated transmission temperature gauge so that I don't have to deal with the ScanGauge II for just that. I haven't decided where to mount this gauge yet (I don't want to loose the A-pillar driver side grab handle).

    It looks like most of the gauges come with a 1/8" NPT temperature sensor.

    • Where is a good place to add a T-fitting to add this temperature sensor? I was thinking along the inlet line to the radiator before it starts to get cooled. I assume that it won't loose much heat in that short of a section after leaving the transmission.
    • Does hot fluid flow by the "hydraulic test port" on the A340f that I could insert into?

    “Go with the B&M, I tried the Tru-cool and in the 90F+ Houston summers it wasn't cutting it. A local transmission guy showed the the B&M and it was night and day difference. Don't worry about over cooling, over this last winter we had days where it was 32-35F. The B&M's internal bypass allowed my transmission to heat up to 95-100F within 10 minutes of highway driving and it stayed there all the way into town. Also the B&M is MUCH more well built.” - http://www.yotatech.com/f2/external-cooler-would-better-narrowing-down-208959/

    No update since my original post other than I am most likely going to get an ATF cooler by selling my truck and picking up my dad's 2005 Tacoma TRD that includes the tow package (including the aux transmission cooler) :)

    To the OP and others, if I may... "commandeer this thread" (i.e. in a friendly way of course ) :D... I bought the B&M Tran Temp Gauge and got that all working, but eventually want to mount the Hayden 678 Oil Cooler that I have. However, the problem, there seems to be no room "up front" between the grille and the A/C Condenser unit :eek::confused: and I will take pictures if anyone wants me to? The one thing I do not want to do is "zip tie" it to the radiator and/or condenser unit! I would like to put it up front to get max airflow. Any ideas on how I should do this? One option that I noticed, was just behind the bumper underneath, BUT after thinking about it, not a really good idea :eek:

    It is for a 2.7L Reg Cab 4x4. The thread that shows this, my stupid mistake, must have been for a 6cyl eng :confused: The pictures of the front end, hoses, just about everything, looked like mine, with about the only exception of the horn. Finally, I really don't want to do any heavy modifications, cutting into the chassis or anything of that nature. The grille however, that I'm willing to slightly modify to make it fit, if I can. If it will help anyone, if anyone wants to help that is, I will take a picture of the front with the grille on and the grille taken off.

    BTW, when I TESTED the gauge I was getting right around 160F (typical) during the day. If I can put a cooler in, even though I really don't tow anything, it would still be nice to drop the temp a little more and/or have that ability to do so.

    Finally, I didn't want to start another thread since one was already started AND it is basically what I would have started eventually anyways, if that makes any sense :confused: A-pillar gauge pod... DIFFERENT STORY ALL IN ITSELF:annoyed:

    Thank you in advance guys/gals.

    Happy Wheel'n
