run fault codes and look for faults in idle sensor---MAF sensor

In some cases, the throttle body is dirty or the iac valve is faulty.
I would start with those two things.

Do you own a professional type scanner ?
007 Idle Speed Problems Scan Data for Idle

• does the engine miss? bumps is a rythmic pattern?
• an engine miss will appear to diminish at higher rpm due to centrifical force.
• other possible problem broken or flat motor mount.
• is the idle rough in reverse?
• if not
• open hood
• start engine
• Left foot on brake (hard)
• start engine
• watch engine as you select drive
• still holding brake with left foot / throttle gas with right foot
• does engine dramatically move?
• if so replace motor mount on offending side
• if not possible engine miss or transmission problems

it could be that the tick over is two slow in brive,,,
set it up to tickover at 850,,950 rpm (in drive)
or it could be a gear box fult like the drive plate has a crack in it,,,letting the torque converter slap about,,,
chech tick over first,,, bont adjust tick over in gear unless the brakes are held hard on,,,

Yes, most likely a fault in the auto transmission, and the car has shut itself off to prevent further damage.

probably a dirty idle air control valve

Sounds like a possible vaccume hose leak?
