this Electronic Shift Improver may
worsen the condition.
When installing your B&M ShiftPlus+
Electronic Shift Improver there are
several other B&M products you may
wish to consider:
B&M SuperCooler Automatic
Transmission Coolers: We feel that
it is very important that every vehicle
used in heavy duty and hi performance
applications (racing, towing, RV, etc.)
should have an oil cooler. Heat is the
major cause of transmission failures,
and an oil cooler is an inexpensive
safeguard against overheating and trans-
mission failure.
B&M Trick Shift Performance Auto-
matic Transmission Fluid #80259
Trick Shift performance automatic trans-
mission fluid is the industry’s only real
performance ATF. A specially blended
oil with foam inhibitors, extreme pres-
sure agents and shift improvers, this
fluid assures protection while delivering
the fastest possible shifts. You literally
“Pour in performance.”

The B&M ShiftPlus+ Electronic Shift
Improver is engineered to improve the
shift characteristics of your automatic
transmission. The shifts will be firmer
and more positive when the ShiftPlus+
is switched to position 1 or 2. This
ShiftPlus+ has been designed to work
on all 1993 thru 1998 GM vehicles
equipped with the 4L60E and 4L80E
electronic automatic transmission. This
transmission can easily be identified
by reviewing the build code decal,
typically located in the glove box or
center console. If either an "M30"
(4L60E) or "MT1" (4L80E) code is
present, this unit will work.
We recommend that you read through
the instructions completely before
beginning the installation, so you can
familiarize yourself with the
installation procedure and tools
required. Check the tool list at the
end of these instructions for the tools
required to install your B&M ShiftPlus+
Electronic Shift Improver.
Installation of the B&M ShiftPlus+
can be accomplished by anyone with
minimum mechanical experience. It
is however, important to closely follow
the instructions.
NOTICE: The B&M ShiftPlus+ Elec-
tronic Shift Improver is not a cure-all
for an ailing transmission. If your trans- PCM (Powertrain Control Module)
or Computer is mounted either un-
der the hood or under the dash. See
Figure 1 for more information.
STEP 2. Once you have located
the PCM, carefully remove the wire
loom(s) from the PCM, allowing
easier access to the wires.
STEP 3. Determine where you
would like to mount the head unit.
Make sure that the wires will reach
the PCM (if the PCM is under the
hood, you will need to drill a 3/16"
hole in the firewall to pass the wires
through).
STEP 4. Carefully clean the back
of the head unit and the mounting
surface with rubbing alcohol and a
cotton ball. Using the supplied hook
and loop tape, carefully attach the
"loop" tape to the back of the head
unit. Attach the "hook" tape to the
mounting location inside the ve-
hicle. Note: For best results, allow
the tape to cure for 24 hours before
attaching head unit to mounting
location.
STEP 5. Carefully route the wires
and the control unit under the dash,
making sure to mount the control
unit where there is adequate air
circulation (the control unit will get
warm under normal operating con-
