2015-2016 Duramax CCS TCM Tuning Add-On (EZ-LYNK)

Note: This is an upgrade to your existing CCS Tuning. Do not purchase this unless you have an EZ-Lynk already.

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

Note: If you purchased the 4-Week Lynk Package you will need to upgrade to the Lifetime Lynk Package when adding TCM tuning.
