    I'm using mine K5 towing sometimes, will original oil cooler in radiator be good enough, or do I have to change it with a new one, size?
    Thanks

    If you're towing and your truck has a 700r4 tranny, an auxilliary cooler is MANDATORY!!!! 700r4s hate heat and will self destruct, especially if you're towing heavier loads.

    I have a TruCool(made by Long Inc.) cooler with a 22,000 GVW rating. It was a breeze to install and works great. Make sure to run the aux. cooler in series with the rad tranny cooler. Also, try to buy a stacked plate design- the old aluminum tube/fin designs aren't as efficient or tough.

    I would like to 2nd CanmoreK5's post. Get the largest stacked-plate cooler you can find. I use a 24,000 lb. one with my 700R4. I pull a 4,000+ lb. 25' travel trailer with my truck, with no problems, even with the 35" tires.

    A TH 350 doesn't have a lockup torque converter so I'd think it's almost as important to have it on there as it is the 700R4.
