The 6L50 transmission mated with the 2.8L Duramax engine has been around for some time. When driving a stock 2.8L LWN, you'll notice how out of sync your 2016-2019 Chevy Colorado or GMC Canyon throttle pedal and acceleration rate feels. The OEM tuning in the 6L50 waits too long before utilizing torque converter lockup. It also leaves MPG on the table by shifting late and running unnecessarily high RPM. With Calibrated Power's TCM tuning, they take advantage of the torque made by this engine. Shifting the transmission sooner and getting the torque converter locked up to raise powertrain efficiency and give you the best MPG possible. This custom TCM tuning also electronically controls line pressure and shift timing to give firmer shifts and make sure the trans has enough hydraulic pressure to hold those clutches tight with the new found torque.
