## NHTSA's summary

Flash: Transmission Shift Quality Improvements This bulletin involves flash reprogramming the Powertrain Control Module \(PCM\) with new software.There may be two software packages to choose from. Both software updates will fix all symptoms/conditions listed. Refer to Service Bulletin 21\-008\-12 for details about the software choices. Some customers may notice any of the following: Harsh 1\-3 upshift while operating in Economy \(ECO\) mode. Harsh 2\-3 upshift while operating in normal mode.For 2012 model year, the harsh 1\-3 upshift in Economy Mode and the harsh 2\-3 upshift in Normal Mode was corrected in the revised software enhancements that were released in Service Bulletin 21\-008\-12 dated March 23, 2012. 1\-2 upshift clunk following a throttle back out \(2012 \- 2013 model year only\).In addition to correcting the previous Symptom/Conditions, the following enhancements have been made to improve the shift quality of the 62TE transmission: Shift schedule changes for the 1\-2, 3\-4, 4\-5, and 5\-6 upshifts and the 6\-4P, 6\-5, and 5\-4 downshifts. Fifth gear torque converter lock\-up/unlock improvements.
