Thanks Mike. I find the TCU code a little easier to work with than the ECU.

Yeah. Thanks. Every little bit helps with the research.

I have the 92 and 94 JDM bins. I upgraded my 92 car to the 94 firmware just in case it helps the transmission last longer. I haven't analysed the differences yet

I've just been looking at a Legacy TCU from 1990. It doesn't have any of the "overheat mode" processing. I suspect that Subaru may have added the overheat mode in an attempt to overcome transmission overheating problems with the early SVX prototypes.
