ML Gearbox problem?

[panason1c]

Todat, I stopped my ML on a farm track with a slight incline and chatted to a friend for 5 minutes, during this time the engine was running with the lever in 'P'...when i eventually tried to move off in 'D' the car just rolled backwards down the track and also the engine wouldnt rev very high, it felt 'restricted'...i selected 'N' and then 'D' again and the car reluctantly began to move forwards but it felt as if the handbrake was partly on (of course, it wasn't) i then continued on and tried using the tiptronic function but the gears wouldnt move from the one it was already in (the gear indicator on the dash showed 'D' all the time) i then stopped the engine and restarted it and the gearbox resumed normal behaviour!....
Any ideas as to whether i suffered a one off 'glitch?...or is this a sign of worse things to come?
Thanks

PS...The 'box oil and filter were renewed with MB parts approx 15k mikes ago, the level was checked recently and found to be ok.

Seems that mine was a 'one off' glitch.......no probs since.

Don't suppose you had the left foot touching the brake pedal whilst you were trying to accelerate?? That causes that kind of behaviour. Easy to do when you are on a hill start.

No, Left foot was well clear of brake pedal......it definately went into 'limp mode' and only reset by stopping/re-starting the engine.
