Tranny heating up

    Hey, first off I have an 02 2500 Dodge 4x4 with a Cummins in her. Last spring I spent a bunch of $$ on the auto tranny. Any way to make a long story short, it heats up even during light plowing (we haven't had a good dumping yet!) The guy that rebuilt it bypassed the factory cooler because it was plugged and put in a massive aftermarket cooler just near the big hole on the front bumper.
    I just serviced the tranny last week, filter was full (only about 5 k) no metal in the fluid (thank god) just band material. The tranny guy adjusted the bands and bumped up the pressure in the valve body (?)
    Now I did notice the the new cooler isn`t completely exposed in that factory hole in the bumper - would shifting it over a few inches make that much of a difference? I am really getting p*ssed about this as you can imagine!
    Only mods on the truck are - Superchip programmer (that I run in tow) and 50 horse injectors. I don't plow hard with the truck and yet she keeps getting warm!
    I want to give the guy the benefit of the doubt, and he does a lot of tranny work..just that I am getting frustrated, lol
    Any help would be appreciated - thanks

    I forgot to mention, only heats up when I have my 8.5 Extreme V hanging off the front.

    my guess is your not getting enough air to your tranny cooler, plus your fan isn't coooling it off at all either. i think you need to use the stock cooler. i doubt there much air at all that even gettingto your cooler. ats diesel makes a cooler with electric fans if you want to go that route. whats your temp reading?

    Had a different Tranny guy look at it today - hopefully hooking up the factory cooler/heater to the aux cooler tomorrow! Have a Snap-on scanner hooked up to her now to read temps. accurately, did 230F this afternoon scraping a yard.
    I may order a fan for the aux cooler tomorrow and a real temp gauge.

    there is something wrong with your fluid and or cooler I have a winter cover on my truck ( entire front grill covered with plastic ) at all times in the winter and with the plow on the front I never see temps past the 140 mark on my trans gauge


    when you are parked try to leave it in N instead of P it gets the fluid moving around better see if that helps

    Fluid is new (last week) - but the guy that rebuilt it by-passed the factory cooler for some reason. It is going to a different shop today to have it hooked back up.The aux cooler he did put on is big - 9X11 with 1/2 inch lines in/out of it. I may have to add a fan to the aux cooler if she stay's warm.
