    Are you sure the truck did not come with a transmission cooler??? I though all 2500HDs cam with at cooler. They are pretty simple to install though. All automatics have as a minimum a loop that goes to the main engine radiator. Place the auxiliary cooler on the feed line from the transmission.

    it should go like this:

    Transmission >> Aux Cooler >> Main cooler (on radiator) >> transmission.

    By having it in this order you still get the warming effect when needed. Believe it or not, you can cool it too much.

    I had one instaled today on my 87 S10 Blazer, $51.00 for the part. Don't know how big it is as it was dark when I picked it up.

    Big towing Trans coolers are pretty cheap to buy.
    It will have one into the radiator but maybe not one in front of the radiator. If you put one in you have to take the return line to the trans and run it to the new cooler. Then the return line from the cooler goes to the transmission.
    Do it in all hard line,no kinks,no crimps, no rubber tubing! Tie it all down with wire ties so it does not move. Look at the radiator area on the the truck.
    You should have (back to front) the radiator, A/C condenser, then like a 6" X 12" little radiator which is your Trans cooler. I bet your Chevy has a cooler.

    This is the incorrect position.... It must go between the transmission and the engine radiator line... if you put it on the return line you run the potential of over cooling the transmission fluid. The fluid has a proper operating range and sometimes need to be "warmed" up by the engine radiator.

    You know, I don't think I've ever heard it described that way anywhere except on this board. I've got a chart that shows temperatures, but doesn't say anything about low temperatures (minimums). I would think that since any gear changing (and driving in lower gears without the lock-up torque convertor engaged) creates lots of heat, I don't really see how it could ever be too cool.

    I'm not disagreeing with you, I've just always put my cooler AFTER the rad tank... and always had good success. Maybe putting it before would be better on a plow truck...

    And just think of the stuff we can do with $20 worth of brake tubing / fittings and $65 of Cooler. Why the whole system of lines.
    Labor kill's you!
