gearbox problem

[triston]

hi.i am driving a 2012 x5. recently i noticed my car vibrates a little when i step on the accelerator during low gear. when i am in high gear this does not happen.i googled the internet and thought its likely a coil or spark plug issue.i sent in my car to a small mechanic.they tested the coil and spark plug and said the problem remains.in the end they told me they are sure its the gearbox issue. they use the term transmission valvetronic. they said need to change the gearbox which if course is going to be expensive. i am just not so convinced that my car problem is so serious that the whole gear box got to be change.the vibration experienced is mild. the car is still moving quite smoothly otherwise. can any bmw expert comnent on my issue?
thanks so much!

A friend 528 faced similar issue. Change transmission oil and problem resolved. Worth a try IMHO though BMW never recommend changing it.
