    The only nervous part I had of install was cutting the hard line to install a compression fitting. I had a tubing cutting in my tool box and it made short clean work of it. The hard lines slide and clip into the OEM cooler and new EAD fittings. I just looked at the new fittings for a few minutes to figure the clips out. A small screwdriver popped them right out. Very easy! If you are using the bypass, you will be using rubber hose to connect.
    I also purchased the bypass with the TruCool, but I did not install it. I read somewhere that my 2008 with the HD tow package may have an internal bypass. I also just replaced the OEM cooler with the TruCool so the fluid will run through the radiator first anyway. I guess when the cold weather arrives I'll find out if I need it. Seeing as my truck is a "garage queen" for most of the winter I don't forsee a problem.
    If you have any problems feel free to contact me, or 99, or mfleet.

    If you have the OEM trans cooler, you have the tow package. I'm not sure if that has a bypass though.
    I believe the bypass is for applications which completely bypass the radiator. Maybe someone can shed some light on that?

    Mfleetwood answered that earlier in the thread. To wit, he said:

    Hope that helps...

    I just got the cooler and mounting kit. How long did it take you all to install yours? Just wondering how much time I should set aside.

    It took me around an Hour and 15mins, from start to finish, I would say give yourself at leased 2 hours, Mfleetwood and XS live would be able to give you a much better time fame, as to how long your going to need to do the install....as all of you have NNBS Trucks....
