PREPARATION
4L60E Transmission:
The OptiShift TCS currently supports 1996 and newer 4L60E transmissions.
Support for the 199 -95 is planned in the near future.
4L80E Transmission:
Pre-199 4L80E transmissions use a different internal wiring harness and pass-
through connector. This early harness has a problem with leaking fluid at the
pass-through connector. GM recommends upgrading to the newer connector
and wiring harness. Because of this, we do not provide a wiring harness for it. If
you have one of these early transmissions, it will be necessary to upgrade to the
199 + internal wiring harness.
The Bosch pressure control solenoid used in pre-1994 4L80E transmissions is
not compatible with the OptiShift TCS. You will need to upgrade it to the 1994+
Holley solenoid. The older Bosch solenoid is silver, while the newer Holley
solenoid is black. If your solenoid is already black, you have the right one and it
doesn't need to be changed. The GM part number for the Holley pressure
control solenoid is 8684216.

CONNECTING THE OPTISHIFT
Step 1: Power
Connect the power wire (red with 7.5A fuse) to the 12V switched power source
of the Engine Control Unit (ECU).
If your vehicle doesn't have an ECU, connect to another 12V ignition-switched
power source.
Step 2: Ground
Connect the ground wire (black) to the main ground of the Engine Control Unit.
Connect wire as close to the ECU as possible.
If your vehicle doesn't have an ECU, connect to solid ground as close to the battery's
negative as possible.
Step 3: Throttle Position Sensor / Accelerator Pedal Position Sensor
Connect the Throttle Position Sensor signal wire (green) to the Throttle Position
Sensor (TPS) signal input of the Engine Control Unit. If the vehicle has
Electronic Throttle Control, use the Accelerator Pedal Position (APP) Sensor
instead of the TPS.
For carbureted and mechanically-injected Diesel vehicles, connect the TPS
Feed (orange), TPS signal (green), and ground (black) to the Throttle Position
Sensor.
See the "Throttle Position Sensor" section for details.
Step 4: isc. Connections
Connect the Neutral Safety Switch and the Backup Lamp Switch.
Step 5: Accessories
Connect your optional accessories.
See the "Optional Accessories" section for details.

NOTES ON INSTALLATION
General Installation:
The OptiShift unit should be mounted within the passenger compartment of the
vehicle in a protected location. Good mounting areas include under the dash,
behind a kick panel, or under the seat, as long as the unit and wiring are not
subject to damage. Under-hood mounting is NOT possible with the OptiShift
unit. It is not waterproof or rated for under-hood temperatures. Passenger
compartment mounting is also necessary to provide easy access to the USB
port, which is used to interface with a PC for programming and diagnostics, as
well as the display and function control knob. For this reason, be sure to mount
the unit in a way that gives easy access to the USB port. If you will be using a
desktop PC for programming, install the unit so that it can be unplugged and
moved easily.
All electrical connections should be made using 60/40 rosin core solder. Cover
the connection with heat-shrinkable tubing for improved insulation and
mechanical strength. Individual connector terminals can be connected using a
“piggy-back” method, where the terminal is removed from the plastic connector
housing to allow the new wire to be soldered on to the terminal atop the original
wire. Two wires may be connected together by twisting them together
longitudinally, soldering, then covering with the appropriate size heat-shrink
tubing.
Adaptation for Factory-Equipped Transmissions:
It is possible to use the OptiShift TCS in a vehicle which was originally equipped
with one of the intended transmissions. This could be done in conjunction with
an engine management system upgrade that no longer supports the
transmission. Use of the TCS for this purpose allows flexibility in choosing the
engine management system, in addition to the increased control, performance,
and transmission durability afforded by OptiShift. If you retain the stock
PCM/VCM, it can probably be modified or re-flashed to disable the transmission
functionality.

Identifying the Terminals of an Unknown Throttle Position Sensor:
This is a procedure for identifying the correct terminal connections of any
potentiometer-style throttle position sensor (almost all three-terminal TP
sensors). A DVOM or analog Ohmmeter is required.
1. Set the meter to resistance mode and set it to a scale that can read up to 10K
or 20K Ohms (if it is not auto-ranging). Please keep in mind when setting up and
reading the meter that "K" means thousands of Ohms. In other words, 15K
Ohms is the same as 15,000 Ohms.
2. Connect the meter to two pins at a time while operating the lever or cam of
the TPS. Watch the meter while rotating the sensor. Check all three pairs of pins
until you find a pair that does not change resistance when you rotate the sensor.
The two pins that do not change resistance are the fixed ends of the resistance
element (+5V and ground). The remaining pin that did change is known as the
"wiper". It is the moving contact that slides along the resistance element to give
the varying voltage. This is the output terminal of the sensor and should be
connected to our green wire (Vehicle pin ).
3. Next, with the sensor at the idle or closed throttle position, measure the
resistance between the wiper (output) and each of the end terminals (the two
whose resistance did not change in step 2) of the sensor. The end terminal with
the lowest resistance to the wiper (at idle) is the ground terminal, and should
connect to the black main ground wire of the TCS (Vehicle pin 16). The terminal
with the higher resistance to the wiper is the 5 volt reference input to the sensor
and should connect to the orange wire (Vehicle pin 11) in our harness.
General Guidelines for setting up Throttle Position Sensors:
The linkage to a throttle position sensor should use most of the rotating range of
the throttle position sensor. This can be adjusted by changing the ratio of the
linkage. Also, please make sure that a small amount of the sensor's travel is
being used at idle. You will want a TPS voltage at idle of at least 0. 5 volts. This
is done to allow the TCS to detect problems with the TP sensor. For instance, if
the sensor becomes disconnected or the linkage falls off, the TPS voltage will
fall below the set idle threshold. If the TPS voltage goes below the idle
threshold, the TCS assumes that the TPS is bad and will switch to failsafe line
pressure and default shift points. This is done to prevent damage to the
transmission from low line pressure and will provide a safe "limp home" mode.
