ml55 amg gearbox stuck in park

[jmldn]

I have a 2001 ML55 amg that is stuck in park on the auto gearbox.It has been fine but today i started it but it wouldn't come out of "P" on the gearbox.Could it be a sensor via the brake pedal?

Could be the automated lock.
You should have a slot near the gear gate and a metal bar in the tool kit (see the manual). Pop the bar into the slot and it should override the lock out.

You need a new brake light switch. This is very common.

changed the brakelight switch but no different.

The problem has to be on the selector, if it is showing R when its in P it wont start. the lever will also be locked under this condition. as it is showing R the fault cant be anything other than the selector cable being out of adjustment.

Well it could be the range recognition switch - after all it's this that tells the transmission control module the selector position - used primarily for the 4321 positions as the selector rod is disengaged here (there isn't a cable as such - it's a rod assembly).

The rod goes down to the box, but it is a cable that goes up to the switch, it should only be a matter of re setting it all.

Are we talking about the same thing Malcolm? There isn't a cable from the rod to the recognition switch - it's a fixed assembly.

Hi Stats, Yes there is a cable from the ignition switch,down to the selector ass;

Surely that's an electrical connection not mechanical?

Its called the ignition lock control cable,your car has one.

It's a mechanical device? I thought the transmission control module controlled the starter lock out relay - the sender for this is in the electric control unit in the gearbox - an item that needs checking as the socket leaks ATF into the ECU harness.

its item 35

it prevents the gear shift from being moved with out the key of the car

Thanks Malcolm. My car doesn't have that system - a later addition?
