I installed some coolers from Genos garage. Now days there are a couple options, one is Fast Cooler that is a spacer that uses your original PTO cover, and the other is by Trans Cooler that is one piece and has fins inside. The fast cooler gives you 2 quarts extra when you install both and the Trans Cool only gives you 1 extra quart because of the fins inside taking up space that could be oil. I choose the Trans-cool version for 2 reason: 1: only one gasket to leak from instead of 2 per cooler. And 2: I thought the concept of having heat sinks inside may pull more heat to the outside. Who knows if it will and I might have burned myself out of an extra quart of cooling. Besides the quart mine give I added another quart in through the shifter tower. So six quarts of Red Line MT-85

It is real hard to direct compare before and after because the traffic for me living in the city changes so fast and so much. A 20 mile run to my shop this morning at 34 degrees outside with just the truck no trailer gave a case reading of 108 degrees with the factory mopar 85w oil that was getting real brown. The return run that had stop and go traffic but was near 60 degrees out was 108-110 on the steel case same point from the mornings measurement. But the new fins of the coolers heatsink where 97 to 113. And the close fin on the heatsink by the exhaust was 132 and 150 on the exhaust. I am adding a link to a thermal image and the regular image for clarity. The addition of using the Red Line 85 made no difference shifting wise from how it was before it is the exact same.

No problem...

I got a fast cooler on one side filter on the other I also have mac high tech rear disc cover with 8 quarts of Amsoil. When I used to tow trailer a lot more often my rear end was pretty warm to the touch, after Hi-Tech cover and double oil capacity it is now warm. So I know it worked for me. As for coolers, I did not measure temperature before I only put the probe in after cooler installation. As for wrapping exhaust with a blanket I made a heat shield and clamped it on. Not sure if it helped but I want to think it did.

Might want to catch the diff cover thread. Someone can point you to the videos. I'm on the road.

If you're talking to me, I have seen them and like mentioned above no outcome yet. I got rear cover when I got the truck before much research, but it did lower my temp by feel, I didn't have a temp gun then, just putting my hand on axle was pretty warm before rear cover and later I could let my hand rest on axle it was just barely worm. Could it be more fluid, probably, all I know is it helped. If I had to do it again, I probably wold not spend the money on it. I probably wouldn't spend half the money I did... but knowledge comes with time and if you don't know you have to pay.

I found both the Fastcooler transmission coolers and the MagHytec differential cover I installed on my truck to be effective and did what I was looking for...

Your tranny is almostmas well oiled as mine, externally that is. But under carriage has you beat hands down. The good thing, no rust anywhere.

You gonna make me want to check it now, you're talking on the filter by exhaust right?

Oh yeah. But looking closer they do look like paint drips. Mine is defintely oil. Leaky rear main seal and maybe some blow by from the head. Parking the truck on Monday to pull the head and we will see about the vlow by. 465k on this engine.

Just say that you used oil based paint.
