Transmission Control Module: Service and Repair
Pinion Factor Setting
STANDARD PROCEDURES
The vehicle speed readings for the speedometer are taken from the output speed sensor. The TCM must be calibrated to the different combinations of
equipment available. Pinion Factor allows the technician to set the Transmission Control Module initial setting so that the speedometer readings will
be correct.
This procedure must be performed if the Transmission Control Module has been replaced. Failure to perform this procedure will result in an
inoperative speedometer.
To properly read or reset the Pinion Factor, it is necessary to use a DRB III scan tool. Perform the following steps with the DRB III scan tool to read
or reset the Pinion Factor:
1. Plug the DRB III scan tool into the data link connector located under the instrument panel.
2. Select the Transmission menu.
3. Select the Miscellaneous menu.
4. Select Pinion Factor. Then follow the instructions on the DRB III scan tool screen.
