PLEASE NOTE: These BLUE
ISOLATED transmission mounts are the replacement for our previous RED
ISOLATED transmission mounts. The only difference is color. This change
was made to eliminate confusion between our red isolated mounts and our red bolt-through mounts.
GENERATION 2 now shipping!
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. |

What's a Transmission Mount?
The transmission mount is an integral part of the drivetrain support
which isolates the cabin from powertrain vibration and noise when you
drive your car. To understand the technicalities of the transmission
mount, there are a few items that should covered.
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.
Our 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?

Order BLUE ISLOLATED version
with this part number.
These are fully isolated, having two
seperate mounting bolt hardware pieces embedded in the material just
like the black rubber and OE BMW bushings. The urethane is a higher
durometer (stiffer) material than the rubber and offers nearly the
same drivetrain motion control as a solid delrin or aluminum mount, but
with significant vibration isolation. That last detail makes it a
better choice for a track car that is occassionally street-driven,
where cabin noise is a concern. While UUC does expect some vibration
transmitted into the cabin, initial user reports say that it is minimal
and certainly acceptable.
