*Don't forget to mail in your customer supplied T43 TCM (located inside your 6L80e transmission). Here is a VIDEO to help with the removal and installation of the TCM.
PARTS INCLUDED: Complete engine and transmission wiring Harness, Engine ECM (PCM-2001, PCM-2003, PCM-2004, or PCM-2006), TCM (8 and 10 Speed only), Pedal (ACC-1007), o2 Sensors X2 (ACC-1039), MAF Sensor (ACC-1046), ECM Mounting Bracket (ACC-1050), 4" LS3/LT1 Mass Airflow Tube/Holder (ACC-1201) and Instruction Manual.
TRANSMISSION COMPATIBILITY:
All 8 + 10 Speed TCM Tuning REQUIRE your TUN (Transmission unique number). Without the TUN#, we cannot guarantee you a compatible transmission as this will verify the year of the transmission. Warranties can not be honored without this information.

6L80/90Es: Must be 2013+ model year transmissions to work with a Gen 5 LT system.
8L80/90Es: 2014-2018 gen 1 model years currently compatible. The gen 2 8 speeds (2019+) are currently NOT compatible.
10L80/90Es: All 2017-2018 Gen 1 10 speed transmissions are compatible. 2019-21 2wd Truck/SUV and all 19+ GM Performance and Camaro are compatible. 2022+ Gen 2 10 speed transmissions with the electronic transmission range select (ETRS) are NOT compatible. These ETRS transmissions will only have a "park" and "out of park" position on the external shift lever on the driver side of the transmission.
FANS; Standard 12v: All gen 5 harnesses come standard with 2 ground triggered output wires. These wires are NOT guaranteed to provide an adequate ground signal to trigger electric fans! On manual transmission applications, these wires will not provide any signal. On automatic applications, the signal cannot be guaranteed as it is dependent on the ECM operating system.
PWM (Pulse Width Modulated): Most GM PWM fans will have 3 positions for wiring. Power, ground, and PWM signal. Whether you are using 1 or 2 fans, there is only 1 PWM signal used. You can use the fan 1 wire in our harness for signal and this wire will be split to trigger two fans. Make sure to fuse each fan’s power supply adequately. No relay is required for PWM fans. Popular PWM fan options would be 2014+ truck fans (dual), 2016+ Camaro (Single), or C7 Corvette (single).
Note, the ECM tune must be setup properly for PWM fans to operate! The tune can be different for different PWM fans as well.
FUEL SYSTEM: PSI systems are setup with a fuel pump relay to send 12 volt power directly to a standard constant supply style fuel pump. This would then be setup with a return style regulator (regulated to 78 psi). Factory LT engines use a fuel pump control module (FPCM) to control a PWM fuel pump. We avoid this system as it does not provide any benefit in a swap application and adds extra expense. If a PWM fuel pump is required for your fuel tank, or you just want to run a FPCM, we do offer an add-on kit (KIT-1006) to accomplish this.
NOTES: This COMPLETE controller kit from PSI includes everything you need to get that Gen 5 LT engine and 6L80E/90E, 8L90E, 10L90E or manual transmission running in your project vehicle. Why use an aftermarket controller for your transmission when you can utilize the Factory controller just like the original vehicle! The kit includes hardware and components that don't typically come with used engines, such as the wiring harness, mass airflow meter, tube with MAF mount, pedal, oxygen sensors, and programmed ECM/TCM - eliminating the need to source them separately. This controller system is a true stand-alone system for use in older vehicles, as all that's needed to get a vehicle running with it are power and ground sources, a fuel pump able to support 78-psi (540 kPa) at the fuel rail, and an electric cooling fan.

WARNING: The installed tune is a base/startup tune, mirroring a factory OEM tune based on the options selected in your order. The tune will remove the VATS (Vehicle Anti-Theft System), bypass VVT (if applicable), disable DOD (if applicable), and remove any restrictions preventing operation of the engine when installed in a different vehicle.
If the engine has a different camshaft, ANY performance modifications, or has any components that differ from options selected on your tune request the following issues may occur: No start, erratic idle, surging, check engine lights, limp mode, lack of shifting, no throttle response, poor power delivery, and other issues possibly rendering the engine inoperable. Any engine or transmission modifications will REQUIRE a custom tune to ensure proper operation and prevent serious damage. PSI Conversion cannot be held responsible for issues related to operation or performance when the engine/transmission has been modified, or varies from the options selected when the tune was installed.
These Harnesses are
designed for retrofitting 2014+ LT1, L83, L84, L86, L87 & L8T ECOTEC3 GEN 5 5.3L, 6.2L, and 6.6L engines and a 4, 6, 8, or 10 speed or T56/TR6060/non-electronic automatic transmissions into older muscle
cars and street rods or newer non-emissions controlled vehicles. They
are completely plug and play with four wire hookup (switched power,
constant power and ground connections required). Harnesses are designed
with a sliding grommet seal and 4 - 5 feet of length from the rear of
the cylinder head to the PCM mounting position under the vehicle
dashboard. A sliding grommet seal allows for professional, leak proof
installation.
Harnesses are professionally constructed from Brand New GM Delphi Connectors and TXL (Polyethylene Cross Linked) High Temperature Wire to GM Specifications.
