NHTSA's summary

Flash: Transmission Shift Enhancements This bulletin involves flash reprogramming of the Transmission Control Module (TCM) with new software. The customer may indicate that they may have experienced any of the following: ? 4x4 Low Mode shift quality during a medium to heavy throttle ? MIL Illumination for DTC P215C - OUTPUT SHAFT SPEED WHEEL SPEED CORRELATION In addition, calibration changes have been made in the following areas to improve: ? Powertrain braking while in Tow/Haul mode ? Downshift response from a medium to heavy pedal ? Drivability at high altitude ? Acceleration performance during cruise control operation This calibration release also corrects a condition where DTC U11C3 may have been displayed when DTC U11E3 should have been displayed resulting in a possible misdiagnosis.

If you do not receive a return call within 15 minutes, proceed with the repair. Please be sure to accurately record any DTCs identified with the scan tool and document them on the repair order.
21-012-14 REV. A2018-06-18. Service bulletin. Transmission Shift Enhancements - Adaptation Drive Learn Procedure This bulletin involves performing a subjective shift quality rating when customers experience poor shift quality and if necessary, performing the transmission adaptation learn procedure. In addition, this bulletin involves performing transmission adaptation learn procedure when the transmission is repaired/replaced and/or the valve body/TCU assembly (mechatronic) is replaced, or when the adaptation memory cells are cleared with the wiTECH diagnostic scan tool. Customers may indicate that their transmission shift quality does not meet their expectations.
