10RStager Installation and Operational Manual 10R80 Transmissions
Rev C
Note: The following instructions are for 8 cylinder 10R80 Automatic Transmission installations for 2018 and
newer model years. Contact True Motorsports for other 10R80 configurations.
This manual will outline the wiring of the 10RStager. Ensure that each connection is a reliable connection that
will not cause any intermittent behavior on the signals. For power connections to the 10RStager, ensure that
the power source is a switched ignition source that powers up when you key on and that it has an appropriately
sized fuse for the circuits connected. The 10RStager consumes less than 0.5 Amps during operation.
The 10RStager must be wired per the instructions outlined in this document and is designed to work for
first
gear and second gear launch setups
. The wiring for the second gear Transbrake is slightly different than the
first gear and also requires an ECU tune that enables second gear launches. The 10RStager will not operate
without interfacing to the transmission and brake pedal wiring. The brake pedal wiring must be wired to prevent
accidental engagement of the transbrake. Note that the foot brake pedal must be engaged prior to pressing the
Transbrake button to engage the Transbrake.
Perform the installation in the following order:
1. Turn the ignition off, open the hood
and disconnect the battery
. Locate the vehicle PCM (Powertrain
Control Module). This should be under the hood near the front passenger side.
2. Locate and install the 10RStager control box in a location that is within the cab of the vehicle. Do not
locate this device in the engine bay. Follow the wiring diagram instructions below and on the following
pages. When wiring up this device, ensure that best practices are followed while wiring up the
10RStager. It is recommended that each connection be soldered and heat shrink applied.
3. The instructions for wiring the 10RStager will be outlined on the following pages. The diagram shown
