    Transmission Oil Cooler

    I saw a picture somewhere around here where there is an aluminum external trans cooler that then plumbs into the standard cooler/heater in the radiator. What are the temps like? Would it be beneficial to bypass the radiator cooler/warmer and just leave it at the external one so when engine temps get too warm, it's not cooking the trans oil.

    I'm asking because based on this company that sells coolers locally to me has this up, and a few other websites and transmission shops have this same info that this site does, just in other ways, and says that if we run at lower temps, we can get heaps of life from transmissions.

    I'm sure it would help, but honestly, I just change the tranny fluid every 30-40k in my sister's Cruze tranny. It's easy enough to do.

    How do you go about changing it? People on here have said it's easier said than done.

    Speaking of transmission cooler, I don't have the auxiliary oil to air cooler that it seems most of the cars do. More so, my cooler that runs through the rad is on the opposite side of the car than what most pictures say it is. I
    Have 2 l flex lines that run on top of the back side of the rad, that then go into the rad cooler, and then return back to the transmission.. I just bought a B&M tranny cooler, so out with the rad one tomorrow and IN with the new. Going for a drive this Wednesday so I'll report back what I get with the cooler and some pics of before and after.

    I'll try and find a diagram again, auto cruze had a cooler but it's not easily spotted. Now on the 2nd gen I spotted something in front but it looks too huge to be a tranny cooler but oddly shaped to be a FMIC.

    I will take some pics. I can assure you there's no auxiliary air cooler. I can follow all the lines, and they go from trans, over the rad in flex lines to the rad, and back to the trans from the rad.

    It shows the lines run from hot side, through rad, into the air cooler, and back to the car, with most of that being on the driver side of the car, but I have my lines on the passenger side, and 2 flex lines that go straight to the rad and back to the trans.
