8L90/10L80 Transmission Tuning

Transmission Tuning Service for GM electronic 8 and 10 speed transmissions. 

Transmission Tuning covers going through the entire trans file and optimizing how the transmission operates.  Part-Throttle Shift Scheduling, Wide open Throttle Shift Schedules, Torque converter lock-up, and Drive mode optimization are just a few of the parameter's that we change to give you a better driving vehicle. 

 Please verify which TCM module your vehicle has prior to Tuning, as some controllers require an unlock service to be performed by HP Tuners before tuning can occur. If you have a T87A or T93 (non Global B) than you will need to have your TCM unlocked. T87 does not require an unlock service. You can find this service at HPTuners.com
