Solenoid Body Identification Procedure

Solenoid Body Identification Procedure

WARNING: Before beginning any service procedure, REFER to Safety Warnings . Failure to follow this instruction may result in serious personal injury.

General Procedure

1. Using the scan tool, select Powertrain, Transmission and Transmission Solenoid Body Identification from the toolbox icon and follow the instructions displayed on the scan tool. The solenoid body identification screen displays solenoid body identification information:

- Solenoid body identification is a 7-digit number
- Solenoid body strategy is a 13-digit number
The next screen displays the current solenoid body identification and strategy data file stored in the TCM (Transmission Control Module). If the solenoid body strategy field is blank, the module contains a partial transmission solenoid body strategy. This is due to a corrupt or missing file at the time the programmable parameters were completed.

2. NOTE: The 13-digit solenoid body strategy number consists of only numbers. Letters are not used.
Compare the solenoid body identification and strategy (if available) to the solenoid body service tag or the replacement solenoid body tag located on top of the transmission case.

3. If the solenoid body identification and strategy on the scan tool match the solenoid body service tag or replacement tag, then the solenoid body identification and strategy are correct for this transmission and a solenoid body strategy download is not required. If the solenoid body service tag or replacement tag is missing or damaged so that it is not readable or does not match the identification or strategy on the scan tool, remove the solenoid body connector and view the solenoid body identification and strategy printed on the solenoid body connector. If it is not readable, remove the main control cover, REFER to Main Control Cover . The 7-digit identification number and the 13-digit strategy number are stamped on the solenoid body.

4. NOTICE: If the solenoid body information does not match the module information, transmission damage or driveability concerns can occur.

Inspect the solenoid body identification and strategy printed on the solenoid body connector and compare this to the solenoid body service tag on the transmission case. If the solenoid body identification and strategy printed on the solenoid body connector does not match the solenoid body service tag or if the solenoid body identification and strategy printed on the solenoid body connector match the solenoid body service tag on the transmission case but do not match the solenoid body identification and strategy numbers displayed on the scan tool, a solenoid body strategy data download is required.
