There are a few things that could possibly be going on. One of those codes is for the shift selector which is the shifter itself in the car. Id check the front of the transmission there are a few solenoids there. YouTube has a video or two of how to clean out the shift solenoids on your transmission. I did it to my auto base Lude and it helped out a lot. Clear the codes and see how long it takes before they come back. If you need to pass smog, they may stay out long enough for the readiness monitors to set so you can pass an emissions test. If your front and rear mounts are shot, I recommend replacing them ASAP to stabilize the engine and trans assembly before you waste out your axles and lower ball joints.
