I suspect a later PCM would have some issues with an earlier vehicle, as the way it interacted with the TCM changed, so quite likely a check light at best, probably would not change gears properly, may not even start

One thing I forgot to mention, maybe you have already done, disconnect battery and discharge PCM by shorting battery terminals for a while

I see this procedure has caused some odd computer problems to disappear on this era Jeep, (and stacks of other equipment)
