1997 Jeep ZJ Grand Cherokee (JTEC PCM): is there a manual/auto trans selector?
And if so, is it working correctly in the current version of the software?

Can't confirm specifically about the '97 ZJ JTEC. And, I don't have anything to confirm if it is working correctly. But, I'll provide the reference info that I do have...
I see that a transmission selection calibration variable exists in my '97 XJ 4.0l 5MT JTEC as:
"[ECM] 440 - Transmission Type: Transmission fitted to vehicle."
I have the 5-speed so this value is set to "Manual".

I have seen a few other JTEC files that have additional transmission configuration calibration variables that are used to set the specific type of AT as well.
