Ask a Question-
What does the Transmission tuning do?
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 clutch disks. It will also change the shifting points to match the new tuning which helps improve the overall driveability.
