I sent my E46 325i in to AB for some work recently. Noticed that the car's gearbox's ancillaries under the car are exposed. Is there supposed to be a shroud/undertray for the gearbox area under the car? AB says there's none. Note: this is not to be confused with the engine undertray which is at the front of the car, directly beneath the engine. The gearbox area underneath would be the area below the gearstick, behind the engine.Helpful responses would be most appreciated.
