This is an upgrade to your current tuning. Do not purchase this unless you have EFI-Live tuning already.
TCM Tuning will dramatically increase the drivability of your 68RFE by modifying and adjusting your shift points, line pressure, and increasing the holding capacity.
Increasing 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.
