Yes. At idle, in D, it thinks about it for about half a second, then dies. 2 dies immediately. 1 does about as fast as D.

If I rev to about 2000 in neutral, let off the brake and shift to D and floor it, it will bog down but start moving, and eventually shift thru the gears as I accelerate. Just not a way to plan on daily driving. If I shift to D without reving the engine and try to let it idle, it dies.

 

That points to the transmission. One of the transmission techs will need to weigh in.

 

I PM’d one of those authorities and have decided to try replacing the TCC solenoid. I’ll report back this afternoon.

 

The TCC solenoid was the culprit. According to @Mark Kovalsky , the TCC solenoid is overridden in reverse, which is how it was able to function that way. Found one available a ways away, installed it about 45 minutes ago, and have been driving/stopping/idling fine ever since. Thanks to everyone that tried to help solve this.
