I threw this clip on Vimeo to share a quick clip from the EMC race last Thursday.

No doubt its heat related.
I never had this problem with my 88 renix XJ and I had an atlas in that and worked it just as hard.
I wonder if I bypass the radiator and just use the trans cooler. Id want to have a temp gauge on the trans if I did that though.

I do have another TCM I can trade out and test. Its in another jeep I own.
the connectors and wires in the trans looked decent when I pulled the pan last time, I was looking at them thinking about that during the swap.
The hard part is I would have to do these tests when the problem is actively...
OK, I give up.
My 91 XJ with the AW4 runs fine but was running a bit warm when working hard in the sand or in 4 low at higher speeds like 15mph. When the gauge hits around 3/4 or so, around 230* I would let it idle and it would cool down. also the transmission would stop working right after it...
