Summary
This bulletin supersedes TSB 25-2131 to add reprogram for later level software, new Steps 1-4 in Service Procedure. Updated Part List with 3 superseded part numbers. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: * Harsh engagement * Delayed engagement * Harsh shift * Delayed shift * Illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771, P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6 and/or P07F7 stored in the powertrain control module (PCM) or transmission control module (TCM). This may be due to PCM software and/or axial movement of the CDF clutch cylinder (7H351) sleeve causing hydraulic circuit leaks. NOTE: If internal transmission service is required to address a concern detected with the CDF clutch cylinder following this article, technicians should carefully inspect, replace other transmission components and flush transmission fluid cooler only as necessary
