E90/91/92/93 M3: UUC EVO 3 Short Shifter Installation
The UUC
shifter comes packaged with all the pieces needed to install their Evo 3 short
shifter. Additional carrier lock pins (circled below) are included if the
installer desires to remove the carrier during installation, as suggested by
the UUC installation guide:
NOTE: The following is provided for information only and any use of
this information by you is at your own risk.
The car
needs to be placed on jack stands for access to the bottom of the shifter, the
easiest way for me to do this was to drive the car on ramps so that I could use
the big jack at the front jack point to lift the car and get jack stands under
the front jack pads (rubber hockey pucks used to pad stands). I use Rhino ramps
with “helper” ramps (2”x4”s with 45 degree cuts) to avoid contact with the
front bumper. I left the ramps under each wheel, never can be too safe when
working under a car:
The UUC
installation instructions suggest removing the exhaust/lower cover plates/heat
shields to remove the shifter carrier. Since I was not installing the DSSR but
only the SSK, I only needed enough room to get to the clip holding the selector
rod to the shifter. In past installations I have been able to bend the heat shield
and then bend it back when finished and it has worked well without the added
labor. The heat shield I needed to work around is at the rear of the
transmission cross-member. I removed the sheet metal nut on the driver’s side
with a 10mm wrench and the bolt on the passenger side with a 13mm wrench to
allow a little movement while bending out of the way for access. Pulling down
the heat shield in the middle under the drive shaft allowed plenty of room for
access (and may even work for DSSR installation), I was able to get two hands
in to position the shifter/selector rod and remove/attach the retaining clip. [NOTE: The
heat shield can most likely be bent a few times and a few different ways (no
sharp angles when bent is best) before it starts to tear/break but it is a lot
like an aluminum can- bend it enough times and at sharp angles and it will
tear/break, this is the risk to using this method. I have done this a few times
and never had one tear/break but that is a decision you ultimately have to make
since you will be the one responsible for any resulting issues]:
The
shifter is held to the shift rod with a C-Clip, it can be removed by pressing
the base of the clip with your thumb or with the help of a screwdriver:
Back up top,
the first thing I did was remove the shift knob (pull up hard), the shift boot
(four clips, removed by tugging upward gently at clip areas), the foam insert
around the shifter, and the carpet around the shifter:
The rubber
boot can be carefully removed as well by pulling up in one spot and working
around the seal until separated. Front and back are the hardest since there is
more seal area there to pull up. Be careful not to rip the boot in the process.
If it is difficult to do from the top, you can always push it up and out from
below. Note the arrow on the boot points toward the front of the car and
remember this when reinstalling:
Note in
this picture of the bottom of the boot the area that goes around the shifter
carrier opening, this can be felt/positioned through the top part of the boot
during reinstallation and should fit securely around the recess in the shifter
carrier at the base:
The
shifter is also held to the carrier with a plastic collar, it needs to be
rotated clockwise to release from the carrier slots it locks into. This plastic
collar can be turned by inserting needle nose pliers or small standard
screwdrivers into the slots located around the perimeter of the collar. I was
able to get the collar turned easily with two small screwdrivers on opposing
sides- once the tabs highlighted are rotated clockwise about 90 degrees they
are free of the slots that retain the bushing and the shifter can be lifted out
of the carrier:
To install
the UUC carrier pivot height adapter, the white ring bushing is placed in the
shifter carrier with the cup towards the top. LocTite is applied to screw holes
on either side of the pivot height adapter and it is placed on top of the
bushing, it should seat around the lip of the bushing:
The pivot height adapter is installed using 6 small HEX
screws, it should sit flush with the bushing in the carrier base and the screw
holes should line up with the slots in the carrier. Screws are installed
loosely by hand and then tightened with supplied hex wrench alternating sides.
After getting one screw on each side started it was much easier to start the
other four using the one installed as a reference point. Be careful to get the
screws just hand tight, no need to crank on the hex wrench For me, installing the adapter this way was
easier/faster than dropping the exhaust/lower plates/heat shields as
recommended by the UUC instructions but if you have a lift at home the UUC
instructions may work better- the screws would definitely be easier to install
with the carrier removed.
(HINT: I found that using my grinder to cut down the hex
wrench allowed for easier use):
Supplied grease is then applied to shift ball, order of
components for installation into carrier from shift ball up should be nylon
cup, spring, spring retainer, and snap ring:
To install shifter in carrier, snap ring pliers are used to
insert snap ring into adapter after shifter is placed in carrier. Now is also a
good time to make sure the height adjustment nut is tight, I found mine was not
and allowed the shift knob to turn although the height was stable. Also note
the slight bend above the pivot ball, the shifter should be installed with this
bend towards the rear of the car after the snap ring is installed:
Shifter is then connected
to selector rod by placing bearing liners into bearing on either side, sliding
selector rod pin through bearing liners, installing yellow plastic washer, and
finally installing the C-Clip. There was NO way the plastic washer was going to
work with the clip in my case (you can see in the pics that the locking clip
ridge was just flush with the bearing liner) so I left it out- the selector rod
is tight and the bearing liner is the piece that moves (there is no movement
between it and the locking clip) so I am not worried. Since my M3 has 20k miles
on it, the selector rod pin had just enough corrosion on the tip (where the
locking clip slides on) to prevent the bearing liners from going on. I used
some fine red Scotch Brite to polish the ends and some Mobil1 spray lube and
they slid right on. Make sure the clip snaps/locks over the selector rod pin,
the UUC provided clip is a slightly different design that allows the clip to
lock on the rod a little more securely:
Heat shield is bent back
to normal (I was careful when bending it back to make sure the heat shield did
not make contact with the driveshaft) and bolted back up, shifter rubber boot
(arrow on boot towards front of car), carpet, foam, shifter leather boot, and
knob are reinstalled. When reinstalling the rubber boot, the lower seal for the
smaller ring on the carrier around the shifter can be pressed on/around the
carrier opening by feel through the rubber boot as the larger lip is press fit
into the console body hole.
END RESULT: The UUC Evo3 is much more solid and positive feeling when
compared to the OE shifter and is a bit shorter as well. NO added vibration or
noise is perceived and at this point I have not noticed any drawbacks to
installing this, only benefits ;-)
