I have a 95 Nissan Pathfinder, 178000 Miles. Recently, the Battery light, Brake light and AT/tansmission oil lights come on. THe may stay on for a few minutes, sometimes they flicker then go off.
When the brake warning light and the charging system warning light are illuminated at the same time, this is normally an indication that the alternator is failing. I can’t comment on whether the A/T warning light relates to this, and you may actually have more than one problem. In any event, I suggest that you have your alternator checked a.s.a.p.
