  Flash: Transmission Control Module (TCM) Updates This bulletin involves reprogramming the TCM with the latest available software. The customer may notice one or more of the following: When decelerating from a 1 to 2 gear shift, the vehicle may have a harshshift. From a 1 to 2 gear change there may be a perceived bump feeling, whilehaving a light pedal(Sales Codes ETL and ETN Only). A harsh shift from a 2 to 3 gear shift while at almost or wide openthrottle. A harsh shift from a 3 to 4 shift and heavy on the pedal, lifting offthe pedal, then back on the pedal again. While coasting down a grade, an abrupt deceleration may be felt. A clunk heard when shifting from park to reverse or drive. Cold engine flare during a shift. A delay when coasting down, vehicle is in a downshift at low speedsand then trying to accelerate. (The vehicle will have a hesitation as the vehicle tries to change gears to accommodate the new pedaldemand). Excessive shifting(DD and DP Only). Engine flare caused by the transmission releasing the clutch too early duringa 1 to 2 shift. Poor shift quality. Shift or gear hunting. A harsh 2-1 shift. Hesitation in up-shifts and/or down-shifts. Shudder and/or clunk when shifting into gear. The following software enhancements are available:Stored faults can only be cleared by a diagnostic scan tool, this softwarewill allow the TCM to self clear. 2-1 coast down-shift improvements. 1-2/2-3/3-4/4-5 and 5-6 shift improvements.
