Is there a common thread between the charging light, AT trans light and the parking brake light. They all came on at the same time when I started my truck the other day and they never went out. The Alternator is not charging the battery but with the other lights on I wonder if its a bad ground or something. The AT trans light should only come on while you were driving and it was hot. Any thoughts?

I've had two of the tree lights you mention come on before when I lost an alt belt...
But it was a manual too...
you got me on the AT light... I thought when something was wrong with it, the "OD" flashed.

bad alternator! if you let your battery go dead enough all of the idiot lights come on and the rest of your gauges, if you have gauges will stop working.

Check the brushes in the Alt, that's more often than not the cause of a "bad alt". The trans temp could just be unrelated... Have you pulled the trouble codes?
