L5P 6.6L Duramax & Motor Ops ECM Tuning

Note: For 2020+ trucks, an unlocked T93 TCM is required. 

Transmission tuning is strongly recommended if you will be using Motor Ops' high-performance tunes regularly to avoid premature wear. The L5P Transmission does not handle power above 500 RWHP well without increased line pressure. Motor Ops Transmission tuning increases the transmission line pressure which gives the transmission the ability to hold horsepower values up to 600 RWHP. Additionally, the L5P transmission has a calibration that short shifts and keeps the truck a little under the turbo. They extend shift points, refine shift timing, and have redesigned torque converter lockup to improve the drive-ability and response of the vehicle.

Over the past few years of tuning the 2020 and newer 6.6L Duramax, Motor Ops has reviewed many datalogs and customer complaints about lack of consistent power or short windows of power delivery. The culprit is the transmission calibration that the factory used. In between shifts, the transmission calls for an aggressive torque reduction until the shift has been completed. When this happens 10 times over the course of a run the large gaps in power delivery are extremely noticeable.

Their transmission tuning has been developed over the course of countless days behind the wheel making very precise changes to keep you on top of the power when you need it while improving the reliability and longevity of your transmission
