Car starts but cant change into gear
I have a 2008 gl550 and it starts up just fine but I cant put it in gear it just stays in park. When I open my door the displays says door open with car not in park. Does anybody know what I need to do I'm stuck. Thank you

Hi - in this case you'll probably have some stored trouble codes. Do you have a code reader?
It could be the shifter or it could be the transmission control module, or it could be anything in between - a code reader will tell you where to start looking.
Does it go into any other drive selections, such as neutral or reverse?

You need to have someone with star diagnostic test the ISM (intelligent servo module) on the side of the trans and canbus communication between the selector stalk and ISM.

Thanks again for your help I ended up taking it to my cousin's shop and he has one of those real expensive code readers and all he did was earase the codes and it was good to go to was crazy the only thing he said was I need to get a new battery. But now my battery is dead and now my front seat wont move to get to the battery. I've checked all the fuses . When I was able to jump it all the other seats worked fine but not the one i need the most.lol. so i thought just take the seat out. I'm only able to get to 2 front bolts but the 2 back bolts are impossible to get to cause the seat is to far back. Any suggestions???

If you were able to get the car running, then that seat should move (obviously). Is there a separate fuse for the passenger seat motor? Also, look underneath to make sure there isn't a plug that's not connected.

+1.
You don't even need to start the vehicle. Just attach the jumper cables to a good battery (and to your vehicle, of course), turn key to position 2, and you should be able to adjust the seats.
Alternatively, apply 12 volts directly to the seat. Detach the power cable from under the seat and use any 12 volt source.

12v to my seat to get it to move. HELP!!
So it looks like I need to hook up a 12v to my seat to move it. Does anybody know what wires under the seat I hook it up too?

You didn't mention if you checked for a separate fuse or if you checked for plugs being disconnected (remove, reseat).
Are you sure you can't get creative with tools?
If the seat motor is kaput, it's kaput. Jumping 12V to it isn't going to make a difference.
