From what you are describing and from your type of vehicle,this sounds like an issue with the idle air control valve being faulty.This should be located on top of the engine near the throttle body.graphic

i thought that might be possible although car is on in park or neutral or is it only happening in gear since its under load

Yeah the iac valve can act really weird when it is going bad and have symtems at random times.I don't believe it is a trans issue considering the vehicle takes off and drives fine and there are no codes.
