Transmission problem, without reverse AGAIN

[J.Seven]

My 2000 X5 4.4i is again with transmission problems. I had exactly this same problem on 2008 with 150.000Km on the clock, now with 200.000Km on the clock same problem again.

If I am in a horizontal plan, it moves very very very slowly while in reverse, but if there´s a sligh ramp it just doesn´t move at all. All the other gear work normaly, so it´s not the clucth otherwise it wouldn´t move forward too. Only the reverse gear doesn´t work and I don´t get the " Trasmission safe mode" notice on the dash. This is a very well known problem on these ZF gearboxes ! The only difference from 2008 is that in the morning where engine is cold I still have reverve and gearbox works normally, but after 20 or 30 minutes ride with engine warm, I loose the reverse !!! That is weird don´t you think?

Back on 2008 I ended up making a rebuild and thought that it could last at least another 150.000Km but only 50.000Km after the same problem is back, but on 2008 car was in Europe where there´s assistance, now I´m in a distant place in Africa and no assistance anywhere nearby. Have already seen some UK website to order a remanufacter gearbox, it´s the only solution any other ideia???

Here´s my thread with failure gearbox back on 2008
