High tranny temperatures are almost always associated with frictions failing or torque converter failing.
Not in my case! And I don't think so, many variables with this stuff. I will update and hopefully close this nightmare thread now.
Firstly, I gave in and purchased the Controller Tech DRBiii emulator. Works perfectly, unlike their rental nightmare unit which barely worked at all. Had a bad USB port that was loose or something which would mostly NOT work. I figured keeping this crazy jeep for long haul I'll need it again. I had enough of reading the chinese clone stuff and trying to get it to work, though I may still try the solder (purchased a video microscope to micro solder and nice solder station). Even people who successfully ground whatever pin it doesn't always work for them.
I fixed two different things today. Wheel speed sensor drivers side. That wasn't hard, have to remove brake caliper etc to get to it. I measured the ABS module side and got my 12V. I also measured resistance of old sensor and new one. Both measured the same 350k or so. Doesn't mean they both work though. Read the ABS module, cleared code, and read the MPH with DRBiii
and it was all good. Previously it read ZERO. ALSO, as before with rear differential speed sensor, the outside ambient temp read way off, like stuck at 83 or something when 100+ out. Once I fixed the sensor it returned to normal readings. Silly Chrysler engineering...ugh.
For the transmission cooling mess, I disconnected lines and ran a clear tube between them I had. started jeep in park and it was flowing clear and perfect, could even feel it like a water hose. Turned off. I took another clear tube and blew through the cooler (bottom of condenser) making sure I had a good seal, and it was very hard to blow! My best guess it has an issue or is clogged somehow. Rare...but call me a first WWDIESEL hahaha.
Secondly, I installed Oreilly Hayden 11x11 cooler on drivers side. It barely fit, kept hitting the fan etc on the left side. I made a couple of brackets and hung it from top and sort of zip tied the bottom. Just used black rubber hose and the left side is sort of pressured against the metal of the bumper. I'll keep eye on it but it's too big to fit there properly. It's either make a sharp 90 and kink it or some pressure against it going straight down. I sort of ran it 45 degrees to the right to compromise between the two, it could last years like this or fail tomorrow, don't know. I think it will be alright but I may worry about it. If this all works I may get a fan forced cooler and mount it in the back somewhere. But I prob won't if it keeps working lol.
DRBiii reported about 150 degrees driving around tonight at 81 or so ambient temps, random backroads stop and go. It got up to 155 or so when I stopped. I will drive it again tomorrow when it's 104 or whatever in the afternoon and see what it reaches. I hope it's not above 180 or so! Transmission shifting perfectly.
I'm cautiously optimistic, I think the problem is resolved. Stock cooler has a restriction to flow and isn't in best location either.
