Why should you get TCM Tuning on your 68RFE? Read about it here

The CCS TCM Tuning is for those looking to upgrade their tuning package from Coopers Custom Solutions by adding Transmission Tuning. The TCM Tuning will dramatically increase the drivability of your 68RFE by modifying and adjusting your shift points, line pressure, and increasing the holding capacity.

TCM Tuning increases the line pressure, this puts more pressure on your clutch packs and prevents them from slipping which can cause excessive early wear on 68RFE's clutch disks. It will also change the shifting points to match the new tuning which helps improve the overall driveability.

The factory lockup schedule on the 68RFE is set to lock up the torque converter in 4th gear, and Mitch Cooper (Owner of CCS Tuning) will command lockup in 3rd gear and it will stay locked while you are shifting from 3rd to 4th. The shifting patterns would almost be similar to when you drive in Tow Haul Mode.
