My Father's 2000X Mercedes E430 has an intermittent problem with the automatic gearbox. One of two things happens. Either:
1. The gearbox goes into neutral while driving (usually on acceleration), and refuses to go back into gear.
2. The gearbox gets stuck in one gear and will not change either automatically or by overriding with the tiptronic function.
In either case, pulling over, switching off and restarting the engine cures the problem for a while.
My instinct is ECU - especially since restarting fixes it. Any suggestions?

Really need to get a diagnostic check to see if any faults stored.However the most common fault on this model and year is the shift selector module which is the whole unit that the gear lever is attached to.Unlikely to be the g/box ecu.hth
