Service bulletin V011415 2026944

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

Technical Bulletin (Update Programming issue due to Harsh Gear Engagement from Park to Drive or Reverse): The updated programming for the TCM modifies clutch operation to decrease pressure to the C1, which may cause harsh transmission engagement. The production solution for this issue was a Transmission Control Module (TCM) software update. This document discusses the "Fault Codes" necessary to diagnosis, and potential remedy of the issue. The fault codes for checking warranty coverage for servicing the vehicle are also available.
