# Service bulletin BBJA46597

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.

## NHTSA's summary

"Job Aid \- If you suspect a torque converter shutter/vibration, a test\-drive snap shot may help isolate the source of the issue. Follow the instructions for the HDS or i\-HDS below to capture and evaluate the snapshot for torque converter shudder and current software in the PCM. \- If the data shows RPM fluctuations similar to the examples of a torque converter shudder, replacement of the torque converter, a software update, and/or transmission fluid replacement may be necessary; refer to the applicable service bulletin repair procedure. \- If the snapshot does not compare with the sample snapshots of the faulty torque converter and look similar to the snapshots of known good torque converters, the torque converter is not the source of the vibration; continue with normal troubleshooting."
