I was getting a "bang" noise from the centre/rear of my car in transition of gears. It then evolved into a very severe also "banging" sound and it would also shove the car forward, felt like getting hit in the back by another vehicle. So i took the car to a trusted indy, and he told me that the propshaft/diff are all fine but the "gearbox bearing" was gone, or something of the sort, and that i needed to go to a gearbox specialist to get it sorted as they dont do that type of work. Really annoyed about it, it sounds like an expensive job, and i'm not sure what indy to take it to? and i also dont know what kind've parts are they gonna put into the gearbox thats possibly not MB?
