Understanding the ATS Five Star Co-Pilot
The ATS Co-Pilot transmission controller is recommended for use with light duty pickup trucks
when a heavy-duty aftermarket transmission and torque converter package have been installed on
vehicle. While the Co-Pilot will still function perfectly on a stock transmission, factory transmission
shafts are weak and prone to breakage. The factory torque converter clutch will also fail if applied
under high load conditions. Factory computers are programmed to disengage lockup under certain
conditions which will protect the transmissions internal components under higher load. This is why
we recommend having a heavy-duty aftermarket transmission installed in your vehicle to prevent
transmission failure. ATS Diesel Performance sells many parts for all levels of trucks that will
strengthen your transmission and improve reliability, whether you have a stock daily driver or a
fully built race truck! Give us a call today if you feel the need to get a fully rebuilt transmission for
your truck, or if you just want to strengthen your current transmission with a few upgraded parts.
Our experts can help answer any questions you have and guide you in the right direction.

Co-Pilot Adjustment
The control panel on the face of the ATS Co-Pilot allows the driver to adjust the lockup of the
transmission. Keep in mind that the Co-Pilot will only lock the torque converter when enough
boost is reached. This keeps the engine from bogging down due to excessively early converter
clutch lockup that is commanded by many factory Transmission control modules. The adjustments
allow you to trim the converter clutch lockup based on MPH. To raise the vehicle speed at which
the transmission locks up, you press the up arrow button. To decrease lockup speed, press the down
arrow button. When the torque converter is locked, the Co-Pilot will display a green light to
indicating that the converter has locked up. Due to the protection the Co-Pilot provides and the
engine load sensing of the Co-Pilot, it is not possible to command Lock-up at too-low engine speeds
or low torque levels. This unique feature ensures the engine will never bog or run at a low engine
RPM, thusly causing lugging when the engine does not have boost. At the other end of the
spectrum, during high power output when the engine is running at full load, the Co-Pilot will keep
the torque converter clutch engaged, allowing full torque to be transferred through the torque
converter clutch to the transmission input shaft. The factory often disengages the torque converter
clutch during these high torque conditions to reduce the load exerted on the factory transmission
shafts. This is the primary reason we do not recommend installing a Co-Pilot transmission controller
on a stock torque converter or transmission.
The ATS Co-Pilot will need to be set up for your vehicle and application. The Co-Pilot will need to
be disassembled to access the dip switches on the electronic board. You will need a 1/16th - inch
hex (Allen wrench) to remove the face from the Co-Pilot. After the face has been removed the
electronic board can be slid out of the casing from the front. The digital face is attached to the
circuit board with a ribbon cable; do not force the board from the case. There are four (4) switches
on the circuit board; the switches allow the user to select the features desired. The settings are listed
below. When reinstalling the face on the Co-Pilot do not over tighten the 2 small screws on the face
or faceplate failure will result.

Co-Pilot Module Mounting Location
Find a convenient location to mount the Co-Pilot module with in reach and view of the driver. The
Co-Pilot interface must be within visual range of the driver as well as in easy reach. We have found
the ideal place to locate the module is just to the right of the driver on the lower dash panel just
above the right knee. Use the Velcro supplied to secure it to the dash. Before sticking the Velcro to
the dash use brake clean or acetone on the area the sticker will be. Run the Co-Pilot wires that are
to be wired up to the PCM (Power-train control module) and the transmission through the firewall.
Between 2003 and 2004 Dodge moved the PCM from the Passenger side firewall to the Driver side
engine block. Follow the instructions for your application. This kit is for Dodges with the PCM on
the firewall.

Wiring the Co-Pilot
The Co-Pilot has several connections that need to be made in order for it to function properly. There
are several wires which are optional but still included to give the Co-Pilot a more versatile use
depending on your trucks current setup. Use the diagram below as a reference when installing your
Co-Pilot to avoid any conflicts or confusion.

-Gray Wire- Exhaust Brake –PIN #13
If you do not have an exhaust brake, skip this section.
Reason for use: This function allows your aftermarket or factory exhaust brake to turn on with the
Co-Pilot torque converters lockup when decelerating only. OPTIONAL
If you do not have an exhaust brake, leave the Grey wire unconnected.
Locate the exhaust brake solenoid. There should be 2 wires coming off of the solenoid. One wire
delivers power to the solenoid via a power switch mounted inside the cab. The other wire supplies
ground to the solenoid. The ground wire that comes from the solenoid to the ground on the engine
must be removed and connected to the gray wire that comes from the Co-Pilot module. The
Exhaust-brake feature of the Co-Pilot will only work with an exhaust brake that uses a solenoid to
actuate it. We recommend the use of a Pacbrake with our Co-Pilot. Some exhaust brakes do not
use a solenoid, instead they use a computer module. In this case you will need to add a relay in the
circuit to control the exhaust brake or use the Co-Pilot as a stand-alone unit. We have supplied
wiring diagrams that detail the connection to a Pacbrake.
You can use the warm-up feature of your exhaust brake by simply turning off the Co-Pilot
Box and turning on the exhaust brake’s toggle switch.
Please note: If you are installing a Pacbrake now, or in the future, you do not need to make
any Pacbrake connections at the ECM or install the Pacbrake ECM Bypass Kit.
