Further, for owners of 68RFE automatic transmission equipped trucks, you have the option to add transmission tuning. One of the major benefits of having such an electronically controlled transmission are that so many factors, such as converter lock up, line pressure, and shift patterns can be controlled electronically.
Transmission Tuning Details:
- Earlier Converter Lockup
- Increased Line Pressure to 175psi (Built Pump Can Go Higher)
- New Shift Strategy to Keep From Lugging
- Easier Downshift with Less Throttle Input
- Torque Management Tailored
VERY IMPORTANT-PLEASE READ
Due to firewalls in the factory ECM, you will be REQUIRED to first unlock the ECM. At the present time, the only way to do this is using a Bully Dog GT (part number 40420) tuner and the Bully Dog Unlock Cable, which is available from the menu below. In doing so, you will merely need to unlock the ECM, but not actually install any tuning from the Bully Dog. Once this is complete, you will be able to use the Bully Dog in a different vehicle, but you can only unlock one vehicle with each tuner. Another option is to use the Bully Dog for digital gauges in the vehicle that the EFILive will be installed into. At the present time, the Bully Dog is NOT COMPATIBLE with 2015 Cummins but there will be a step for you to flash your 2015.
