Manufacturer summary

Original wording in English

Replacement TCMs don’t come with trim data. After installation, you need to run a teach-in (hydraulic pressure characteristic calibration) procedure with the HDS. The problem is that A/T DTC P287C (transmission adaptive values not learned) is set, which prevents teach-in. This happens because the TCM is programmed to look for trim data any time the ignition is cycled. If the TCM doesn’t see that trim data, it sets A/T DTC P287C. If any DTCs are set, the TCM won’t initiate teach-in and, as a result, can’t learn the trim data. It’s a classic catch-22 situation.

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.
