The gearbox is a QuadraDrive the same gearbox that the Grand Cherokee 2012 has.
the fluid from the gearbox was never changed-
the 15000 Km service was made every time except this time ( it has 17 000km and i still dont have the money to do it) (i used only the oil and filters that the dealership sayd)
what is the KEy DANCE ?
I not quite sure of your meaning here. The 2.7 CRD Grand was built in Austria not Australia and I've never heard any talk of them having the engine added seperately. The petrols Grands were built in USA, the diesels in Austria. But yes it does have the same engine and box as the ML270, although just about every Merc from that vintage and beyond run a version of that gearbox.
Also as Fango says you do not have the same gearbox as the 2012 models, they are now Fiat (VM) powered and as far as I know do not retain the MB gearbox. Quadradrive refers to the transfer case and differentials but you still do not have anything in common with the 2012. The transfer case is the same as the V8's with a variloc style arrangement for locking in high range with a positive lever operated locking in low range. The diffs have the variloc centres known as Quadradrive but from the next model on they became Quadradrive II and the version of that on the current models is slightly different again, mostly that they only have it in the rear (at least here in Australia).
I'm not sure of your comments about the gearbox fluid and what your current mileage is but if hasn't been changed then that could be a real source of your problems. MB originally stated this gearbox was sealed for life and did not require servicing but soon realised this was not possible. The fluid in this box should be changed at normal auto gearbox intervals based on your driving habits.
you refer to oils from your dealership which i'm guessing is engine oil since you state the gearbox has not been changed. I can't stress enough that make sure your dealer is in fact using the correct oil, do not take their word for it unless their is a wealth of knowledge over there for the 2.7 CRD Grand (known over here oficially as the WG). Given there appears to be no strong Jeep forum over there with talk of the 2.7 I am guessing the knowledge base with your dealers could be as average as it is here. Your gearbox oil is different to waht is used in the petrol Grands and even I believe in some of the later models with a version of this box. The fluid must comply with MB spec 236.10 or later. (Note this is different to 236.1 which is not an abbreviation for the 236.10)
Yes as Fango and I have noted the 0700 code is next to useless for diagnostics, so you'll need Jeep to delve further. You could do the oil but if it's locked in hard limp the dealer will still have to clear it so maybe it will be easier to start with them.
Was the 0700 the only code you had.
The issue could be anything from the cam sensor, to the ABS, to the speed sensors inside the box.
