A little background: I'm running 35's, geared 4.88. This is my second transmission/TC combo doing the same thing(this trans ran cool in the jeep it came out of). I have a fan cooled auxiliary cooler inside the front crossmember and behind the winch bumper. Not an ideal location but space is tight.
With my infrared temp gun I get 220 at the pan, but at the cooler I'm getting 190 in, and 180 out. This is driving in 80* temps, normal stop and go city driving.
The fluid is fresh, still red, does not smell burnt. Dex/Merc 3.
I feel that I'm not cooling the fluid enough. There doesn't seem to be anything wrong with the trans. It shifts fine, does not slip, will lock up in d and od just fine.
My thoughts are to get the fittings from jegs and do away with the QDs, run braided lines to the front and try to get my cooler into fresh air, maybe even out on the bumper above the winch. I'm at a loss as to why the cooler isn't doing its job better. The lines have been removed and blown out to make sure they are not stopped up.
Is there anything else, internal to the trans, that could cause it to run hot?
Like I said above, two low mileage used trans/TC's in a row and I still have a hot running trans. It's got to be how its cooling(or not cooling)
I'm lost on this and ready to take drastic measures to get this rig back on the trail and reliable again
