Subject
The Powertrain Control Module (PCM) electrical connectors on about 70,000 of the above trucks may allow water to enter into the connectors. Water
and the resulting corrosion in a PCM connector can cause the speed control and/or transmission overdrive function to become inoperative.
Repair
The three electrical connectors on the PCM must be removed and inspected for corrosion. If no corrosion is found, the connectors must be sealed by
installing rubber 0-rings onto the harness connectors.
If corrosion is found in the connector, the transmission wiring harness and PCM must be replaced.
