Manufacturer summary

Original wording in English

This P/I advises to replace the valve body, not the TCM, for DTCs P1787, P27EC, P187E and/or P18A1 on vehicles equipped with an ETRS trans assembly.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
