722.6 gearbox trouble please help

[Dan2k7]

Hi guys, gearbox is playing up in my partners ML270. About 6 months ago whilst I was driving it, it went into limp mode. Could only get 3rd gear and wouldn’t change.

I checked fluid level and it was slightly low. I replaced the pilot bushing, filter, gaskets and put fresh fluid in.

Car drove fine until a couple of days ago when it refused to drive in gear. It revs up but doesn’t move. Turning on and off got it going again but I’m concerned something serious is going wrong. Any ideas? I’m wondering if it’s possibly conductor plate or the gearbox ecu? Any help much appreciated.

You will have to get the codes read first. You could waste a lot of time and money otherwise.
It could be the conductor plate; it could be that previously fluid migrated up to the TCM; it could be the shift sensor.

Pull the codes and take it from there.

Thank you I have a carsoft scanner. I will scan it and post back with the codes.
