My 99, ML430, 33,000 miles, and out of warranty has a problem with the shift lock. I am able to shift from Park to any other position without the key in the ignition or my foot on the brake.
Is there anything I can check without taking it to the dealer? The last thing replaced under warranty was the transfer case. Is there any elecrical connection near there that may not have been reconnected?
Thanks for your help in advance.

Best Regards
