A popular and inexpensive upgrade for the transmission mount is the installation of the BMW 320i tranny mount.

Originally used on the older E21 3-series, it's cylindrical shape deflects less than the mounts found on recent BMWs. Installing the 320i mounts requires very little modification, and it yields significantly less deflection without any additional vibration or otherwise uncomfortable side effect.

Testing of the stock E36 M3 tranny mount and the 320i mount showed that the 320i mount deflected 24% less than the E36 M3 version (a good thing). In the effort to find a solution that would yield even greater results, UUC Motorwerks began research the various options.

There are replacement aftermarket tranny mount systems which do a notable job of addressing transmission movement, but at the expense of excessive interior cabin vibration. Additionally, such system can cost upwards of a few hundred dollars. Like all UUC Motorwerks products, our goal is to create products which can be used in a daily driver while maintaining the benefits for performance driving. Such is the case with the Tranny Mount Enforcer.

The Tranny Mount Enforcer is an add-on piece to the 320i mount which inhibits a noticeable degree of deflection. The Tranny Mount Enforcer is CNC'd from 6061-T6 aluminum. For best results, we recommend using the specially-designed UUC Transmission Mount Bushings which do not require the slight modification to the transmission cross brace that the 320i bushings do.

UPRATED TRANSMISSION MOUNTS BOLT THROUGH RACE RED

!!! LIFETIME WARRANTY - INCLUDING RACE USE !!!

New mechanical retention system on all UUC isolated transmission mounts (red or black) and engine mounts. This design uses a bonded end plate plus an inner plate embedded in the urethane. This inner plate prevents separation of the mount assembly even under excessive force.

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 even under the most abusive conditions. Offers effectively the same drivetrain motion control as a solid delrin or aluminum mount, but with some vibration isolation to reduce vibratory stress on mechanical components. Cabin vibration significantly lower than delrin/aluminum solid mounts, but still noticeable.

Vibration Absorber.
First and foremost, the purpose of a transmission mount is to isolate vibration from the interior cabin. Without it, your interior cabin noise will increase to the point where it would be uncomfortable to drive any significant amount of time.

Deflection Fighter
The transmission mount is also used to combat transmission/powertrain movement during driving. Since the transmission is connected to the back of the engine, it is the engine which is doing the twisting when one accelerates or decelerates (engine braking). Since the engine has it's own mounts, the transmission also has it's own. Whereas some movement is expected, too much movement will cause the transmission to become misaligned with the interior of the car. When the transmission is not in the same position, it may lead "mis-shifting" (shifting into the incorrect gear). Generally, a mis-shift causes 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 Mount
The ideal transmission mount will both absorb vibration as the factory intended as well as minimize the amount of transmission movement during spirited driving. By firming up the transmission mounts, your gear shifts will become more precise than when you car was new from the factory.

UUC bushings even incorporate the small notch required for certain models including E46 330i/Ci 6-speed.

Hundreds of drivers from daily driven cars to full blown race cars have gained the benefit of the TME with near elimination transmission movement. Speedvision teams such as TC Kline, Turner Motorsport, and ERT to name a few, have all benefited from the TME. Are you next?
