# Service bulletin LI27.19\-P\-072588

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

Complaint Transmission control unit Y3/8n4 \(fully integrated transmission control unit \(VGS\)\) not listed in quick test and/or no communication possible with VGS. Cause Transmission control unit Y3/8n4 Remedy For vehicles with 722.9 transmission: Ensure LI54.15\-P\-057373 is performed before replacing any component parts. After processing and complying with the above document\(s\): 1. Perform an ignition reset on Y3/8n4 \(VGS\) 2. Inspect transmission connector for loose connections, damaged wiring or pins and any other concerns If communication with the VGS cannot be established, the complete valve body \('electrohydraulic controller unit \(EHS\)'\) must be replaced. Installation of a VGS repair kit is not permitted in this case as it is not possible to transfer the necessary valve characteristics without communication with the original control unit.
