    I am considering putting a Hayden Transmission cooler on my 2010 Taco (base model 4x4)since i bought a new travel trailer. The trailer weighs about 2500lbs dry. Do i have to do the tranny flush to install this or can i just add more fluid? My truck only has 16000 miles on it so it seems to me the tranny flush is a bit of a waste. And yes i did the "search''and didnt find an answer. Thanks

    Concur--I added one and didn't bother flushing, just topping up. It's a real easy mod.

    I originally had the Hayden cooler after the radiator cooler. I think it made it too cool, especially in the winter. I later changed it to in line after the radiator cooler, and it seems happier. It does reduce the cooling some, but there is such a thing as too much cooling with a transmission.

    Edit: I have an Aeroforce gauge that tells me transmission temps.

    So you just add a couple of quarts of fluid and all is good?

    What kind of temps does your transmission indicate?

    I have an oem cooler on my prerunner. Picked up a scangage II and have it showing trans fluid temp.

    My transmission in summer traffic (mixed highway/street metro driving) is about 140-145. Winter probably runs 125-140, depending. Heavy traffic and high heat will probably see 150-160, and the converter temps can get up into the 170's in stop-and-go. It comes down fast once moving again, though.

    Open highway the temp tends to drop, since you're not working the transmission much and air is flowing good.

    With a light load in the bed (3-400 lbs?), going up very steep & windy Oregon back roads I've seen it hit 190*, but that's pretty rare for me.

    Before I switched the configuration, I was seeing regular temps around 100-105*, which is a bit too cool IMHO (can't even check the fluid level until it hits 115).

    Picture of what? The lines, gauge, cooler?

    Because it doesn't have a dipstick, and it's a crazy transmission, there is a temperature check procedure. The fluid needs to be between 115 and 135 degrees, IIRC. You can create a jumper and do some acrobatics to make the truck go into "temperature check mode" that will help.

    Or, if you have an Aeroforce/Scangauge, you can read the trans temp there and check it.

    I also added an inline spin-on filter when I was doing my re-route. I originally had a Magnefine, but it leaked. So I went to spin-on (basically an oil filter). Overkill, but it doesn't leak!

    Same here, inline remote filter, Scangage II.

    What filter are you using?

    What was the configuration before that ran so cool?

    I found this in another topic and now wonder which setup is proper setting the fluid level. From the Scangage website, I used the one code they published which is the TF2 set of numbers.

    You could attach the inlet line to the trans cooler, fill the cooler up with fluid, then attach the discharge line, and should be good. Best way is to do that, then overfill the trans with the rest of your quart and do the temp check mode method to be sure you are at the right level.
