EZ Lynk GDP T87 TCM Tuning (2015-2016 LML Duramax)

GDP T87 TCM tuning calibrates the transmission control module on 2015-2016 LML Duramax trucks through the EZ Lynk platform, so shift behaviour matches the engine calibration.

What it does

• Recalibrates shift points, line pressure and torque management for the T87 TCM
• Keeps shifts in step with the added power from ECM tuning
• Delivered over the EZ Lynk cloud

Fitment

2015-2016 GM Duramax LML 6.6L with the T87 transmission control module. For 2011-2014 LML with the A50 TCM, see part GDP411033.

Requirement: GDP ECM files must already be on the vehicle before TCM files can be purchased. Transmission tuning is written against the engine calibration and is not sold standalone.
