TRANSMISSION COMPATIBILITY:

All 8 + 10 Speed TCM Tuning REQUIRE your TUN (Transmission unique number). Without the TUN from your transmission you may experience shifting issues, communication errors, no gear progression or other issues. 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: Fan control functionality is dependent on the operating system your ECM requires. Depending on your particular setup fan operation cannot be guaranteed using a relay system like KIT-1010. Fan control and operation can only be guaranteed if using PAC-2800BT.
