New GM Unlocked T87A TCMs Service# 24289543 (MUST CALL TO PLACE ORDER)

MIA's Description

The HP Tuners GM T87A TCM is a brand-new transmission control module designed for purchase. This TCM is compatible with various 2017+ GM vehicles equipped with 8-speed and 10-speed transmissions. It is also found in 2015-2019 GM vehicles with 6-speed transmissions.

This module does not require an upgrade; users can license and tune it directly using HP Tuners' VCM Suite software. Normal vehicle licensing is still required, and credits must be purchased separately.
