Hello, my name is ***** ***** I am a professional here at Justanswer. Thank you for your question and I will assist you with your concern.

The two problem you are describing are not likely related so lets start with working on the shiftier concern. The shiftier is controlled by the shift lock with the signal from the break light switch. Can you check and see if you have break lights and post back with this and we can work from there.

i just checked i do have brake lights...i had the center console area apart i wonder if i did not reconnect something that would cause this issue
Expert:  Ron replied 11 months ago.

If you have the console apart then yes its likely something may have been disconnected. That being said there are 3 fuse that can effect the shift lock. Since the break light are working then that fuse is okay so lets check the other two, both are in the interior fuse panel. Check the CIG fuse (15 AMP) and the ECU-IG fuse (15 AMP) . If the check okay then you are going to need to go back in and check the signal at the shifter . Are you able to do this if I provide the steps and the fuse check okay?

Expert:  Ron replied 11 months ago.

Okay start with making sure the other two fuse check okay and if so recheck the signal at the shift lockk switches. See the steps to do this in the first link and I have also enclosed the wiring diagram in the second link for testing reference.

i checked the fuses and they are in good shape. When I reopened the center console and looked in by the shifter i saw a plastic white connector that was not attached to anything it has 7 spaces across the top row the bottom row has to spaces an open area and then to more spaces. Any idea if this needs to be connected anything?
Expert:  Ron replied 11 months ago.

The shift lock assembly only has the wiring shown in the wiring diagram I sent you , are all these wires connected?
