FAST EZ-TCU Kit 2009+ 4L65E & 4L70

the EZ-TCU does all the work for you! The EZ-TCU is fully configured and ready to run right out of the box ? no tuning necessary. But for those who demand customization, the unit is also optionally fully programmable based on load, speed and RPM. The EZ-TCU programming interface is completely intuitive. There is no real expertise needed if you want to custom program your calibration. The EZ-TCU is capable of real-time switchable calibrations, which allows for multiple setups. Run one calibration on the way to the track, and then, with the push of a button, have a more aggressive setup ready for the race. The multiple shift modes include full manual mode for using bump switch or paddle shifters.
