    Does that 3rd exchanger have a big 4 inch hose going to the turbo with another going to the intake valve?

    Seriously dude if you want to find the transmission cooler then get under the #### truck, find the transmission and follow the oil lines that come out of it.

    The oil lines come out at bottom right front of trans and go up to top of trans. To a long tube about 18 inches long and 4 inches round. There will also be two other hoses coming off that tube going to engine. Those will be the coolant hoses. If you have a air cooler for trans out in front of radiator there will not be any coolant hoses going to it.

    Some have an internal cooler.
    Red ELC Cat coolant and orange-red synthetic gear oil. The cooler was mounted above the clutch housing.

    In that case i have to assist you find a shop in your area that is recommended by other owner operators and tell them to fix it.

    I don't mean to be rude but if you can't figure out where the transmission cooler is then tracking down this coolant leak is beyond your abilities.

    you seem unhappy with life... I found the cooler. It is above the clutch. Even someone who got his CDL yesterday can figure out the option of finding a shop. Hence that recommendation was unnecessary and unwelcome. At this point I wish you would have stayed away from this particular thread.

    Dude you thought the cac was your transmission cooler. That means one thing, you have a very limited mechanical knowledge.
    You quoted me several times asking questions, i gave a direct honest answer.

    Glad you found the cooler, but as had been said, if you've lost 4 gallons of coolant and it's not in the transmission then that isn't the problem. Good luck with the truck. Hope you get it figured out.

    the reason i suspected transmission is because i have no clue where the coolant can go. I've seen a number of blown head gaskets and cracked engines. Pretty sure coolant is not going into cylinders or crank case or overflow hose. Under pressure (or no pressure) there is no visible leak anywhere (inside the cab or outside)... I got no EGR. So like where else could it go lol? I'm about to change the transmission oil and will have it sampled for coolant... I think its level is too high which would explain the lost 2 gal of coolant... will see. Tomorrow (once I get home) I'll do engine oil analysis and combustion leak test just to be sure my engine is as pretty as it looks and sounds:)

    Hey I'm sorry if I am at the wrong thread but I have a question...
    I have a 1999 KW T2000 and it came from US to my country a few years ago and it had some coolant lines cut that were going to transmission..
    I would like to know how to connect them again because in my country we have a lot of hills and we carry heavy loads...
    My transmission get almost 300° at the gauge and I don't want it to be that hot
    The transmission has two hoses at the right side going to the top of transmission into some kind of cooler and from there two more hoses going to cooling system but they are cut in middle...
    Can I change that to oil cooler or would it be a pain in my but?

    Likely those lines were cut for a reason. Maybe the cooler on top was changed to an air cooler, so trans fluid would go to it but doesnt require coolant. Or the cooler went bad and was leaking coolant in to trans fluid so they cut them and just let it continue to circulate trans fluid. The coolant line would be capped somewhere too if they are cut.
