# Service bulletin 21\-013\-12

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10136456
- Published by NHTSA: 2018\-05\-14
- Manufacturer's number: 21\-013\-12
- Manufacturer's date: 2012\-11\-10
- NHTSA component: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); ELECTRICAL SYSTEM

## NHTSA's summary

Transmission Shift Improvements This bulletin involves selectively erasing and reprogramming the Powertrain Control Module \(PCM\) with new software. This PCM software enhancement improves how the shifts are controlled during upshifts \(torque management\).
