The transmission mount is an integral part of the drivetrain support, isolating the cabin from powertrain vibration and noise. Without it, interior cabin noise increases to an uncomfortable level. The transmission mount also combats transmission/powertrain movement during driving. Since the transmission is connected to the back of the engine, it is the engine that twists when accelerating or decelerating (engine braking). Too much causes the transmission to misalign with the interior of the car and may lead to "mis-shifting" (shifting into the incorrect gear). Generally, mis-shifts cause an engine to over-rev and cause extensive internal damage. Especially in an E36 M3, it generally means a few thousand dollars in repairs (and that's why they call it the "money shift"!). The ideal transmission mount absorbs vibration as the factory intended, as well as minimize the amount of transmission movement during spirited driving. By firming up the transmission mounts, gear shifts become more precise than when you car was new from the factory. UUC mounts even incorporate the small notch required for certain models including E46 330i/Ci 6-speed. Red urethane bolt-through transmission mount bushings are the strongest choice. A single bolt through the entire piece eliminates any possibility of bushing material failure.
