Stored my 99 ML 430 for 4 months in a relatively dry warehouse. Disconnected the batttery. Decided to check on the car. Reconnected the battery cables and started right up. After putting it in drive the rear wheel appeard to lock up. After putting in reverse then drive several times it loosened up. Transmission will not go into to lower gears. Need assistance.

 

Did you apply the parking brake when you stored it? Sounds like stuck emergency brake shoes.
Check transmission electrical connector for fluid contamination and scan it for codes. (Solenoid mulfunction)
